What I like most about your channel is the fact that you don't let having a small shop get in the way of tackling amazing projects. You're a scrounger who makes do with what you can get your hands on and are willing to share what you know with a bunch of strangers. Good stuff.
When I was young I played paper and dice RPG's like Dungeons and Dragons, but there were post holocaust genres too and scrounging was always one of those skills my characters had to have high points in - just like real life. I've found all kinds of amazing things in dumpsters and on the side of the road over the years. It's that old line about ones mans trash being another man's treasure.
I've often thought about doing this for my workshop, but these details are above my pay grade. Thanks for doing the work, and explaining it so I understand it. Oh yeah, thanks for showing why all the things I might have tried won't work😬
I showed my nephew years ago how a dc motor and a generator are the same thing. We used a 18 volt battery drill and a dc motor from a broken toy to power a car tail light. We only got around 30 percent efficiency with that set up, but it worked.
Great, after watching your video I must tell you that at my old age, I could definitely make my dreams come true, always thought and wondered about electricity and motors and their multiple uses, I'll be looking forward for some more thank you...

Since your good with gears and have made clocks.. I would love to see a generator that was powered by a tension coil spring that could be wound like a music box or toy wind up car.

How would you supply the mechanical energy? Nothing is for free... right now the best and most efficient way is via hydrocarbon fuels which can be done far cheaper via mass production (natural gas burning plant, coal burning plant, nuclear plants, hydro dams) Hence why we have an entire electrical grid instead of each house producing its own thing.Personally, I can see this happening if we can get nuclear technology downscaled to buildings or neighborhoods. MrFusion sure does sound nice.
@@etherealrose2139 If we can efficiently downscale internal combustion engines to be very tiny but still produce 15 or so horsepower with over 80% efficiency or even 70% then home power generation will become cheaper than the grid.
Br!an Delta V As my pa would say "if 'Ifs' and 'buts' were candy and nuts, then every day would be Christmas." Sadly, even 50% efficiency is still a long ways off. That pesky heat and vibration and noise....

I love your videos and have been watching off and on for about four years. Now I'm basically retired and living off grid and need your advice and guidance on the possibility of making a wind turbine generator from an alternator.
Great video. One suggestion. If you wanted to do this... reverse engineer it. Meaning know your load.. first.. then build a battery bank to hold that power... then build the generator charge the battery bank. It’s so inefficient to run a load directly off the motor. Battery’s handle loads better than motors do when you need consistent energy. I have studied alternate energy for a while. When your trying to move energy from 1 point to another you want to move it the most efficient way possible.
That was very innovative Jeremy, thanks for sharing up the valuable information on the bench testing of generators!!!! Awaiting your next update.. Cheers 🍻 😁 👍🏼 God bless!!!
Similar to a battery charge controller, you can by DC to DC power supplies that can take wide voltages in and give you a consistent voltage out, without needing a battery before the inverter. We used to build these all the time for wind generators (would also be responsible for maintaining a reasonable rotation speed for the blades).
Induction motors don't produce a lot of power in my experience. They have no permanent magnets to induce a current. The rotors can be modified to contain permanent magnets but their effectiveness isn't anything to get excited about. I don't know, maybe I missed something when I tried it, but I get much better results from using my DC motors as generators and they already produce a direct current thanks to their commutators, no rectifier needed. If using it to charge batteries either a charge controller or diodes are needed to prevent the batteries from driving the motor. I haven't used a charge controller for this myself, but I do aim to keep the output voltage around 13-14 volts so as not to damage my batteries.
I am building a human sized hamster wheel that generates electricity as you run. I'm so glad TH-cam decided to recommend your channel to me. This is EXACTLY what I needed to know!!!
That's just unbelievable!!!! I can't get my mind around how people still have the need to force others to work yet I can't still get my own personal slaves!
Not really relevant but your hamster wheel idea triggered me. There's a Monty Python sketch from one of the original shows about the underground world of people dressing up as mice and having mouse parties. I think it was Cleese playing the guy being interviewed and he does it like a recovering addict would. One of the activities he mentioned was people taking turns running on The Wheel. This was the original show back in the 70's which I think predates furries by just a bit. Fookin trailblazers dem boys was!
Mr Fielding, I've come across hydrogen things before, that apparently have been buried. They're not in the public now, how to build them. This gentleman at channel "Hidden Technology", posted a build out of a hydro run generator, "THE GREATEST INVENTION: WATER AS FUEL! The secret of the HH+ compound to boost hydrolysis". Could you peer review if you have time? I'm not sure anyone has the ability to punch out the plates these days, even when we were building out J. Keeley's and other inventors things, it was hard to punch out the plates. Have to wonder who to call to have it fabricated these days, with everything still shut down. Thanks for the videos. I really enjoyed them.
IDK if you read comments in series, on old videos, or if the number is too high to actually keep up. But I was looking for this earlier 9:45. I reckon part two will provide the epiphany I require.
It can work going from Gen to Charge Controller to Battery to Inverter to Loads - try the MPT 7210A charge Controller (12V-10A max range 12.2 to 15.8v) $30.00 - which will come with a Boost circuit. i run all of my lights in the shop with this system for 9 hours - 5 days a week.
Some alternators have regulators built into the case, otherwise look into a Harley or motorcycle regulator/rectifier (relatively cheap) because the stator puts out 24 vac at 2k and 10 vac every 1000rpm after that. Plus you get steady dc power output 14.4vdc
hey about the inverter setup with the dc the motor as a generator try useing a bridge retifier to smooth the ripple ac to dc .unless he motor has a diode of some kind built in witch will also limit your output current and voltage.
If you want to use a self-exciting generator right, with tolerance to electrical faults, use a relay that turns off the load until the voltage rises to where you need it. I've seen this used in a few places where the load will cause the generator to not build up a field. Also these types of generators are very tolerant to overcurrent. If you short the output the output voltage simply gets dragged down, and the motor is unharmed.
I think one of the reasons shunt DC motor did so stable output is another winding SERIES to armature, one which was named COMM field on your schematic. The more current draw (flowing through armature) - the more additional field is created which increases voltage it generates in order to compensate ohmic losses. At least, there were 'mixed excitation' (as we call them in Russia) motors and generators where two separate field windings are used, parallel (shunt) one and series one. It allows very stable output rpm's for motors or very stable voltage for generators. There are some neat tricks of doing generator with NEGATIVE output resistance when it's known there would be pretty long wire connecting it to load. So negative output resistance of generator + resistance of wire will be nearly zero, so voltage at the LOAD is going to be stable. No free energy of course, just we give a hint to generator: 10 amps is drawn, there would be huge voltage drop, so increase your voltage accordingly! Good old tech... This all is obsolete by now: synchronous generator with permanent magnets, rectifier and power convertor / inverter is all we need today...
But maybe this additional winding is located BETWEEN main field windings, then it's another beast which reduces sparks and wear of brushes, ensuring good commutation. This one should also stabilize output voltage to some extent, by avoiding saturation of part of stator and armature core because of 'armature reaction'.
Nice video. Would have been neat to see a power meter on your input motor so you could see efficiencies. Also I'd think it would be easier just to find a used generator and find a new way to power it.
at the 200 watt range I was drawing 530 watts from the wall. I just cut that part of the video because I didn't think anyone was interested in the "misc" details like me :). That just shows how much lost there in between the VFD, the first motor, the belt, the "generator" etc
This is very interesting. Was looking around for shunt dc motor applications, to figure out where I could find one second hand. Seems that large shop power tools may use them? The examples I saw were for conveyor belts and miixers
external voltage regulator(external of alternator) for a older vehicle: 1977 toyota 20r regulator $30 at autozone great option for charging batteries, pay attention to amp rating, i welded one full field trying to regulate 2 alternators with one regulator
I love this channel! I watch a few times a week. I consider myself a student/wannabe. Question: Would it be possible to use and car generator? (… to power a battery). Thanks
A 3600 rpm single phase A/C motor with 4 A/C street light capacitors makes a good generator with a pure 60 cycle sine wave; input power of different types (lawnmower, Savonius turbine, etc.)
It’s probably already suggested,but how about trading out the induction motor with a car alternator which is usually a steady14 volts...I just know this number because of testing charging system with a multimeter while diagnosis of vehicle electrical system...sorry didn’t notice this is an older video....curious of you final results
I think that the should be to have a battery bank that is sized for your energy usage and then have a DC generator that is efficient at a particular output and basically runs 24/7. Somewhere you might use more from your batteries but elsewhere you won't and that's where the sizing of the battery bank is important. In your other video where you had the two treadmill motors connected to each other with the AC motor in the middle, you noticed that when you rotated one motor, the other also rotated, one pulley was slightly larger than the other, if you had another pulley that was just a bit bigger than the larger one, use it and fit a diode on it's output so that it can only output power but not take it, with the two mechanically connected via belts, one should theoretically provide the power to drive the other! Remember, all that you are looking for is self driven ability and enough voltage and current to feed into a MPPT Charge Controller to charge batteries! Personally, I would be happy with 13V at 1A for 24/7 which is actually a lot more than 1A sounds, a solar panel only works for about 8 to 10 hours a day and it's output power is a lot less during overcast days, so having something that is constant is definitely better, you know that it's going to deliver, if you use more today, you know that you will make it up tomorrow, unlike solar, you don't know if it's going to be a good day or not... Wait wait wait, did you use a bridge rectifier on the output of the generator motor? Because when you use a DC motor as a generator, it outputs AC! If it runs at 90V, you should be getting more voltage after the bridge rectifier, that's possibly why the Inverter was complaining! It can't use the bottom half of the AC signal! Did you check the output with the multimeter to see if you were measuring AC or DC? It's easy to miss! Some meters you have to switch it to either AC or DC where others only have one setting on the dial and you have to push a button to switch between AC and DC measurements! I mean, you were running those lights straight off the generator! Were they AC or DC lights? Something doesn't seem right! Would love to see another video on this, it's definitely a popular topic! The two motors need to be geared to be spinning at their optimal speeds so that they aren't using more energy than they should be and producing energy at it's most efficient speed... I just watched the video again! I didn't see any bridge rectifier! Plus, you have a capacitor across the output of the generator and this is a problem! A capacitor will store DC but AC goes straight through like it's not even there! Essentially it's a short circuit! Get a full bridge rectifier and your results will be very different! You will also notice that your getting double the voltage after the rectifier! I really hope that you give this a second go. The fact that the lights that you used Will either run on AC or DC would have been confusing you.
I'm using a old dryer blower and heating elements to heat my small shop works great, but sense it 1/2hp and does just over 2k rpm I double down and put gm alternator on the belt drive of dryer motor. It covers the energy used to run heater more or less.
I wonder how the numbers you’re discussing around the 3 minute mark would change if you were able to keep the speed of the driving motor and the generating motor constant?
I have difficulty following your thoughts (I am not saying your wrong just that I am not up to the challenge) but after listening to your comments on using a motor as a generator would it not be better to use a car alternator or an old dynamo from before they had alternators?
14:20 I might just be a little stupid. Is there a way to buy a "generator" IE, just the rotor/stator assembly? Any time I try to look this up, I get only results for fuel driven generators. I just want the generator half, not the engine. So I have settled on a bank of universal motors salvaged to a genny with a wind or other input (yeah, I fit that trend).
but if you dont connect the loads directly to any dc motor and use a charge controller for battery-inverter setup the voltage would never drop right? so any dc motor would work
How did generators work before digital charge controllers were available? How was the voltage regulated to provide a stable current to the battery/inverter?
Is it possible to create a motor based generator system that you can run off of a battery & receive more watts then its sucking out of the battery? so you can thus use those additional watts for household items & to recharge the battery. I really want to power my house for free & off the grid but without using solar, solar is pretty expensive.
wow you are very informative can u tell me how big of a motor i need to run a 6 to 8k watt genarator head. and im going to power the motor with a separate 120 or 240 inverted from a battery bank got any suggestions or am i wasteing my time thank you for any input
I love the videos, your style and presentation is refreshing and insightful! Thank you! In this video, you sort of casually mention that you are using a three phase motor with a frequency regulator for speed control, and this is the only part of the video I do not understand. Do you have three phase supplied to your shop? If not, please share with me how you are producing three-phase from single-phase, as my boat is three phase and I do not have three phase available to me on the dock where it is berthed. Also, I am intrigued by the idea of using a frequency regulator to control the motor's speed, would you be willing to explain the how and why of this configuration? Thank you again for your delightful videos!
The VFD has single phase input and it outputs three phase. These are available up to about 3-5 hp then they are pretty hard to find because of the power required. I made a video which talks about this in a way that will help. Check out “will a dimmer switch control a induction motor” that’s the best one on this topic. Next would be my how motors work series which is very detailed and practical. No theory just mechanical what you should know.
Wow, you have introduced me to a device that solves a lot of my pain, thank you! I have a boat designed and built with three-phase power, and the only solution I could discover to interface with shore power was buying an expensive and inefficient rotary phase converter, but a little research on ebay and I found listings for 10 horse power VFDs that are affordable for me and very efficient! It is a fun project but this has been a big obstacle, until now! Thank you Jeremy Fielding for introducing me to VFDs, and thank you for so many helpful videos! I am a year away from operating the vessel, but if I can deploy a VFD to power lights and some of the other basic loads then I can re-start the re-fit! :)
I love your channel you are amazing. I am by all means no technician I've been thinking about getting a 22 KW brushless three phase alternator and a brushless electric motor along with a generator power controller I think that's it a battery supply to go off grid don't know how to hook it up maybe you can teach me something thank you
I'm working on turning skateboard wheels into the mechanical input so would there be a suggested motor for the output as a generator? Keep in mind it needs to be small enough to fit the wheel and turn while being on the road. Edit: If you respond please like the comment because otherwise i wont be notified that you responded no I'm not begging for likes I just forgot how to turn the comment notifications back on.
Hello, Mr. Fielding; Great video, I enjoyed it even if I didn't understand everything. It raised a question, tho; Have you done a video converting an auto alternator to a generator? I'd like to see that. Have a GREAT day, Neighbor!
you should get into car alternators! and do videos on modifying them. ppl say they can output 120vac. I have been converting some from 12 to 24v. nice video.
I am interested in the alternator. Several people have recommended it, and I never considered one until this video went live and 5 different people recommended it! When I have some cash I will give it a try.
Jeremy Fielding I admit I don't know everything about them. I do have a good idea on how they work. if you want to modify it I can maybe offer some help or advice. they can be converted to a powerful brush less DC motor. but still be brushed. the rotor still needs current to be magnetized . usually 1.5 to 3-4volts is enough. and about a 30amp bldc motor controller. if you live kinda close I can help you with one. I have been rebuilding them on and off for years. they are simple . once you see what's going on inside. I live in North Carolina. just let me know if I can help. thanks
Could you send me a message on my website? That way we can talk through email privately and take it from there. www.jeremyfielding.com. At the bottom of the page is a contact me form. You will get my direct email after that.
I get how to wire the drive motor as you showed in earlier video is their any special wiring for 3 pH motor to make it produce electrical battery bank power. I am having problems articulating what I am trying to do. 3 pH motor has 3 legs will they all produce power and wired separate. And how can I wire it or am I just confusing my self

Mr Fielding, I've come across hydrogen things before, that apparently have been buried. They're not in the public now, how to build them. This gentleman at channel "Hidden Technology", posted a build out of a hydro run generator, "THE GREATEST INVENTION: WATER AS FUEL! The secret of the HH+ compound to boost hydrolysis". Could you peer review if you have time? I'm not sure anyone has the ability to punch out the plates these days, even when we were building out J. Keeley's and other inventors things, it was hard to punch out the plates. Have to wonder who to call to have it fabricated these days, with everything still shut down. Thanks for the videos. I really enjoyed them.
Great video. I can't wait for the DIY build.
Incredible content! Love the detail.
I have the same multimeter! Best cheap meter ever.
Thank you Jeremy. Informative, as always.
IDK if you read comments in series, on old videos, or if the number is too high to actually keep up. But I was looking for this earlier 9:45. I reckon part two will provide the epiphany I require.
It can work going from Gen to Charge Controller to Battery to Inverter to Loads - try the MPT 7210A charge Controller (12V-10A max range 12.2 to 15.8v) $30.00 - which will come with a Boost circuit. i run all of my lights in the shop with this system for 9 hours - 5 days a week.
Some alternators have regulators built into the case, otherwise look into a Harley or motorcycle regulator/rectifier (relatively cheap) because the stator puts out 24 vac at 2k and 10 vac every 1000rpm after that. Plus you get steady dc power output 14.4vdc
👍
nice job Jeremy. you presented the info very well.
hey about the inverter setup with the dc the motor as a generator try useing a bridge retifier to smooth the ripple ac to dc .unless he motor has a diode of some kind built in witch will also limit your output current and voltage.
i stand corrected good video bro keep it up.
If you want to use a self-exciting generator right, with tolerance to electrical faults, use a relay that turns off the load until the voltage rises to where you need it. I've seen this used in a few places where the load will cause the generator to not build up a field. Also these types of generators are very tolerant to overcurrent. If you short the output the output voltage simply gets dragged down, and the motor is unharmed.
Nice work again wish you would show more of how to wire all the components together ty.
I called out the wiring in the video verbally. Would You rather see a diagram? I could add something like I did in the first video of this series
I think one of the reasons shunt DC motor did so stable output is another winding SERIES to armature, one which was named COMM field on your schematic. The more current draw (flowing through armature) - the more additional field is created which increases voltage it generates in order to compensate ohmic losses. At least, there were 'mixed excitation' (as we call them in Russia) motors and generators where two separate field windings are used, parallel (shunt) one and series one. It allows very stable output rpm's for motors or very stable voltage for generators. There are some neat tricks of doing generator with NEGATIVE output resistance when it's known there would be pretty long wire connecting it to load. So negative output resistance of generator + resistance of wire will be nearly zero, so voltage at the LOAD is going to be stable. No free energy of course, just we give a hint to generator: 10 amps is drawn, there would be huge voltage drop, so increase your voltage accordingly!
Good old tech... This all is obsolete by now: synchronous generator with permanent magnets, rectifier and power convertor / inverter is all we need today...
But maybe this additional winding is located BETWEEN main field windings, then it's another beast which reduces sparks and wear of brushes, ensuring good commutation. This one should also stabilize output voltage to some extent, by avoiding saturation of part of stator and armature core because of 'armature reaction'.
Very good just what I have being looking for
Great job! What about a guard for the pulley?
Great video. Please list the equipment that used.
Omg your the first person to say what is mppt
Nice video. Would have been neat to see a power meter on your input motor so you could see efficiencies. Also I'd think it would be easier just to find a used generator and find a new way to power it.
at the 200 watt range I was drawing 530 watts from the wall. I just cut that part of the video because I didn't think anyone was interested in the "misc" details like me :). That just shows how much lost there in between the VFD, the first motor, the belt, the "generator" etc
This is very interesting. Was looking around for shunt dc motor applications, to figure out where I could find one second hand. Seems that large shop power tools may use them? The examples I saw were for conveyor belts and miixers
external voltage regulator(external of alternator) for a older vehicle: 1977 toyota 20r regulator $30 at autozone great option for charging batteries, pay attention to amp rating, i welded one full field trying to regulate 2 alternators with one regulator
can't wait for the next part!
Great info & description
I love this channel!
I watch a few times a week.
I consider myself a student/wannabe.
Question:
Would it be possible to use and car generator? (… to power a battery).
Thanks
thank u sir,
what types of motor is best to run a 2.5kva 220v generator alternator ?
A 3600 rpm single phase A/C motor with 4 A/C street light capacitors makes a good generator with a pure 60 cycle sine wave; input power of different types (lawnmower, Savonius turbine, etc.)
Excellent job sir!!!! Thankyou!
Well done! Brilliant video, nicely explained.
It’s probably already suggested,but how about trading out the induction motor with a car alternator which is usually a steady14 volts...I just know this number because of testing charging system with a multimeter while diagnosis of vehicle electrical system...sorry didn’t notice this is an older video....curious of you final results
I think that the should be to have a battery bank that is sized for your energy usage and then have a DC generator that is efficient at a particular output and basically runs 24/7. Somewhere you might use more from your batteries but elsewhere you won't and that's where the sizing of the battery bank is important.
In your other video where you had the two treadmill motors connected to each other with the AC motor in the middle, you noticed that when you rotated one motor, the other also rotated, one pulley was slightly larger than the other, if you had another pulley that was just a bit bigger than the larger one, use it and fit a diode on it's output so that it can only output power but not take it, with the two mechanically connected via belts, one should theoretically provide the power to drive the other!
Remember, all that you are looking for is self driven ability and enough voltage and current to feed into a MPPT Charge Controller to charge batteries!
Personally, I would be happy with 13V at 1A for 24/7 which is actually a lot more than 1A sounds, a solar panel only works for about 8 to 10 hours a day and it's output power is a lot less during overcast days, so having something that is constant is definitely better, you know that it's going to deliver, if you use more today, you know that you will make it up tomorrow, unlike solar, you don't know if it's going to be a good day or not...
Wait wait wait, did you use a bridge rectifier on the output of the generator motor? Because when you use a DC motor as a generator, it outputs AC! If it runs at 90V, you should be getting more voltage after the bridge rectifier, that's possibly why the Inverter was complaining! It can't use the bottom half of the AC signal! Did you check the output with the multimeter to see if you were measuring AC or DC? It's easy to miss! Some meters you have to switch it to either AC or DC where others only have one setting on the dial and you have to push a button to switch between AC and DC measurements!
I mean, you were running those lights straight off the generator! Were they AC or DC lights?
Something doesn't seem right!
Would love to see another video on this, it's definitely a popular topic!
The two motors need to be geared to be spinning at their optimal speeds so that they aren't using more energy than they should be and producing energy at it's most efficient speed...
I just watched the video again! I didn't see any bridge rectifier! Plus, you have a capacitor across the output of the generator and this is a problem! A capacitor will store DC but AC goes straight through like it's not even there! Essentially it's a short circuit! Get a full bridge rectifier and your results will be very different! You will also notice that your getting double the voltage after the rectifier!
I really hope that you give this a second go. The fact that the lights that you used Will either run on AC or DC would have been confusing you.
replace the motor with a standard GM truck alternator and you'll get a consistent 14.4V to the inverter
I'm using a old dryer blower and heating elements to heat my small shop works great, but sense it 1/2hp and does just over 2k rpm I double down and put gm alternator on the belt drive of dryer motor. It covers the energy used to run heater more or less.
Use a ultra capacitors pack between alt n inverter. .Looking at summer time evaporator air cooling. Using 5v humidifier modules
Awesome video keep up the good work !
Lol been waiting for this forever
I wonder how the numbers you’re discussing around the 3 minute mark would change if you were able to keep the speed of the driving motor and the generating motor constant?
Very educative, please can you put mechanical energy to any motor to produce power, if no how can you identify those that can.
I have difficulty following your thoughts (I am not saying your wrong just that I am not up to the challenge) but after listening to your comments on using a motor as a generator would it not be better to use a car alternator or an old dynamo from before they had alternators?
A car alternator is a great option
thanx for showing this
excited to see the next step
14:20 I might just be a little stupid. Is there a way to buy a "generator" IE, just the rotor/stator assembly? Any time I try to look this up, I get only results for fuel driven generators. I just want the generator half, not the engine.
So I have settled on a bank of universal motors salvaged to a genny with a wind or other input (yeah, I fit that trend).
Add some heavy flywheel on those shafts.
My rowing machine has a flywheel.
You are AMAZING!! 👍👍👍👍
Good job for sure
but if you dont connect the loads directly to any dc motor and use a charge controller for battery-inverter setup the voltage would never drop right? so any dc motor would work
That's the problem the generating companies have, maintaining a steady voltage/ frequency over varying loads. Constant draw loads loads are easy!
Jeremy you are awesome.
If you put a tensioner on the belt and make it tighter won't it produce more power or volts
Can you recommend a charge controller? Also I am looking for a good inverter charger, any suggestions?
How did generators work before digital charge controllers were available? How was the voltage regulated to provide a stable current to the battery/inverter?
Is it possible to create a motor based generator system that you can run off of a battery & receive more watts then its sucking out of the battery? so you can thus use those additional watts for household items & to recharge the battery. I really want to power my house for free & off the grid but without using solar, solar is pretty expensive.
Jeremy , can you help for my shop made gantry crane project? Like weight calculations
wow you are very informative can u tell me how big of a motor i need to run a 6 to 8k watt genarator head. and im going to power the motor with a separate 120 or 240 inverted from a battery bank got any suggestions or am i wasteing my time thank you for any input
Thanks Jeremy. I love your input and output of videos.
How can I generate power from wind turbine.
Mendelt van Wijk
I love the videos, your style and presentation is refreshing and insightful! Thank you! In this video, you sort of casually mention that you are using a three phase motor with a frequency regulator for speed control, and this is the only part of the video I do not understand. Do you have three phase supplied to your shop? If not, please share with me how you are producing three-phase from single-phase, as my boat is three phase and I do not have three phase available to me on the dock where it is berthed. Also, I am intrigued by the idea of using a frequency regulator to control the motor's speed, would you be willing to explain the how and why of this configuration? Thank you again for your delightful videos!
The VFD has single phase input and it outputs three phase. These are available up to about 3-5 hp then they are pretty hard to find because of the power required. I made a video which talks about this in a way that will help. Check out “will a dimmer switch control a induction motor” that’s the best one on this topic. Next would be my how motors work series which is very detailed and practical. No theory just mechanical what you should know.
Wow, you have introduced me to a device that solves a lot of my pain, thank you! I have a boat designed and built with three-phase power, and the only solution I could discover to interface with shore power was buying an expensive and inefficient rotary phase converter, but a little research on ebay and I found listings for 10 horse power VFDs that are affordable for me and very efficient! It is a fun project but this has been a big obstacle, until now! Thank you Jeremy Fielding for introducing me to VFDs, and thank you for so many helpful videos! I am a year away from operating the vessel, but if I can deploy a VFD to power lights and some of the other basic loads then I can re-start the re-fit! :)
Have you tried a rectifier bridge? Like a diode trio?
I love your channel you are amazing. I am by all means no technician I've been thinking about getting a 22 KW brushless three phase alternator and a brushless electric motor along with a generator power controller I think that's it a battery supply to go off grid don't know how to hook it up maybe you can teach me something thank you
I can't wait.
you need an ac rectifier circuit board its not too hard to design it will definitely drastically improve your performance of V and A
You are getting ac V on the first set up though right? i think you are
get charge controller off a alternator
Thanks good one
I'm working on turning skateboard wheels into the mechanical input so would there be a suggested motor for the output as a generator? Keep in mind it needs to be small enough to fit the wheel and turn while being on the road.
Edit: If you respond please like the comment because otherwise i wont be notified that you responded no I'm not begging for likes I just forgot how to turn the comment notifications back on.
new to the ch but i love it
Hello, Mr. Fielding;
Great video, I enjoyed it even if I didn't understand everything.
It raised a question, tho;
Have you done a video converting an auto alternator to a generator?
I'd like to see that.
Have a GREAT day, Neighbor!
You're a great dude
you should get into car alternators! and do videos on modifying them. ppl say they can output 120vac. I have been converting some from 12 to 24v. nice video.
I am interested in the alternator. Several people have recommended it, and I never considered one until this video went live and 5 different people recommended it! When I have some cash I will give it a try.
Jeremy Fielding
I admit I don't know everything about them. I do have a good idea on how they work. if you want to modify it I can maybe offer some help or advice. they can be converted to a powerful brush less DC motor. but still be brushed. the rotor still needs current to be magnetized . usually 1.5 to 3-4volts is enough. and about a 30amp bldc motor controller. if you live kinda close I can help you with one. I have been rebuilding them on and off for years. they are simple . once you see what's going on inside. I live in North Carolina. just let me know if I can help. thanks
Could you send me a message on my website? That way we can talk through email privately and take it from there. www.jeremyfielding.com. At the bottom of the page is a contact me form. You will get my direct email after that.
Could you hook to charge controller then charge up a battery bank using this generator then from your battery bank to your inverter?
Excuse me sir I wanted to know what kind of a motor u are using for generating dc power
I get how to wire the drive motor as you showed in earlier video is their any special wiring for 3 pH motor to make it produce electrical battery bank power. I am having problems articulating what I am trying to do. 3 pH motor has 3 legs will they all produce power and wired separate. And how can I wire it or am I just confusing my self
Excellent video tnx
Question: Jeremy, is there a such thing as parallel wiring of generators? Just asking. Excellent presentation!!
