Finally ! I have been studying theese videos a lot, but they were bit complicated. Now I can get to build my own bike. Thank you.
You are on the way to doing amazing things! I built E-bikes just for fun, and hope to make it a retirement addition, If I retire before I expire. I know what you're talking about with regard to the different wire colors and connectors. The biggest problems I've run into are always the Displays that the e-bike controllers use. They always fail. I finally went with analog displays and I use my Phone and an app for GPS Speedometer. You can take what you know and with a little imagination, make an e-bike that will take the world of e-bikes to an entirely new level. I've had people ask me about using an alternator to make an electric motor, so people are out there, that might have seen your video. It's all about design, Cool Factor, and Price. You're on to something. If you could take multiple alternators...(I believe that an alternator rotates at 3,000 rpm? ). A Hub Motor is 7,200 rpm. If you configure them into a really cool looking design... And add Capacitors...You could change the whole world of e-bike design and make e-bikes affordable for everyone. An Alternator already has a really cool design. . A DC Motor with no load is a Generator. If you add more than one..You can make a really cool design within the triangular section of the bike frame. Or you could just hide them in a case. I always tell people to keep the dream alive...Go back to Bed... Because that's where dreams become reality.
thank you for the very detailed explanation, because I'm working on this subject, I'm waiting for the next video 😁👍🤟
At last a useful guide on this topic. Thanks very much
with minds like yours in the world, why do we have such an energy crisis? well done mate!
Thank you and Looking forward to your next video of E-bike build
Very nice and very educational to watch your channel.
It appears to amazing torque at low revs!
Thank you for opening the door for various ideas. I can't wait to start on my project soon.
your welcome glad i could help. hope its works for you.
Great videos...Just wondering if the brushless controller is the SPD-481500BLDC...If not
could you drop a link to the controller you're using...thanks...
thanks man helpful series 👍
what kind of controler did you use, can u put a link in the discription.

Love ur videos. Very educational. I have a zodiac 12ft inflatable boat with a 15hp gas motor. Motor won't run, so I was thinking of getting a couple alternator and mount them inside the case at 48v with 2 contollers. Do u think there is a way to control speed of both motors at the same time with one throttle?
Hello,
Great job, would you know the resistance of the coil by any chance?
Thanks,
Sir, thanks for sharing your knowledge with us.
I also do this same convention a week ago.I had a 75amps alternator and I converted it into a motor, but I did it in delta connection.
I had a 80amps rc ESC and it is not calibrated, its a new one. I connected it with 24v(series of 2 12volt batteries).and I used a servo tester for throttle.
When I connected the batteries to ESC I didn't hear any beeps coming from motor.
What is the problem. Can you please help me out to slove this.
Shall I calibrete the ESC using another RC QUADCOPTER motor and then connect it with the alternator(motor). Because I think the coils in alternator are to heavy for ESC to produce those kind of audiable sounds.
Please help me sir
Thanks for the info. I am looking to drive a boat lift crank with a converted alternator using a small rubber wheel against a large (42") pipe wheel. The large pipe wheel turns a shaft that has a 16:1 reduction and requires about 20lbs of force to turn. I need some info of power consumption. I was planning to run it off a car battery that stays on trickle charge using a car battery charger. The area of this that is a mystery is how much sustained power can I generate with the motor, so I can select the correct sized drive wheel.
Rookie question here, could you tell me the difference between using a brushed or brushless controller? Im getting into a Grandad/Grandson project, and bought a brushed controller because i i see brushes for the field coil. I think i have gotten myself a little confused lol. Grrat vids, keep them coming👌
Car alternators are made for dual use 12 and 24V. What the power is you measure off of collectors (where brushes to rotor are)
You can control the speed and torque of the motor by using a pwm to the field coil. Found 12v gives better torque but dropping down to around 5v greatly raises rpms.
i can't remind now where i read, but i searched for "how to control the rotor current/voltage"
and someone said that using pwm in the rotor can mess with the stator running with these pwm controllers
May I have to connect it in star connection as you said in your video and the quadcopter motors are in star connection.
Or I have to calibrate the ESC with another small RC AIRCRAFT motor and then connect it with the alternator motor.
I get struck at this point because iam new to this ESC kind of things.
Please help me .
I'm trying to bypass the controller. I've configured it in delta and added capacitors. I'm running 12V DC to the brushes, but what do I run to the coils?
I'm doing this too but my alternator it had 6 wires so I had the option of wiring delta or star. It didn't work very well in delta so I've wired mine in star, it seems every alternator is different as others have found delta works better for them.
i believe it all depends on how the alternator is wound.
Could you use the output used for the led and a resistor to supply 12v to the field coil?
Do you have hall effect on this motor? I have found without it the motor seems to only work within a specific amount of power range and not at high speeds. I am looking to power a tricycle I have with this setup. I plan on making it a permanent magnet motor.
whats the highest rating esc you can use on a car alternator and are different car alternators different speed power ratings or are all alternators the same
Very nice sir.. How much amp it need from 12v?
What's the efficiency?
How many mAh does the coil connected to the 12V source absorb?
Not much, a few 10s of mA, the field winding only needs to be saturated for the motor to have full power, it is a self exited system after initial charge up as it alternates in polarity as the stater spins with respect to the brushes.
great video simplest way I've seen do you have a link to where you got that e bike controller?
He passed away.
@@health1st189 what?
@@charlesfawcett4178 i heard he passed away 🥴
@@health1st189 well that's no good
after looking all over the internet you are the only one who has made this simple to understand, But I have a few questions. Am I able to run this off of 24v? and what motor controller should i use? (i am making an ebike) Ive been trying to find one that fits the amps you mentioned in a previous video and I just cant find one.
yeah, you can run with 24v on the brushless side (the stator), but i won't agreed for you to use more than a LiPo 2S or equivalent voltage (8,4V) on the field coil
Can I run a small AC 3 phase motor using the same motor controller u used?
hi, i love your Alternator to Motor content
and i would like to request something
i was thinking that it would be nice to use that brushless controller on the stator
but installing hall sensors onto the alternator
and using a 12v brushed controller to keep the field coils energized
creating "electronic gears" for the motor
Thank you. I would like to use it for a kids car so I would likely want to leave the pulley on it and put a belt pulley on an axel for the car and a switch for reversing after stopping.
if you need help you can let an email for me to talk with you
did you run the altermotor without hall sensor? did the controller operates with or without sensors? I asked becauseit wasn't mentioned in the video, I'working on a aimilar setup and this hall sensor is making me sick/ my controller has 5wires hall sensor and I do not have an idea where and how to position the sensors inside the alternator come motor.
Does the battery size effect anyway? I have 2x 12v9ah moped battery and 1 for coils. My motor dont run correct. It dont have torgue and dont even always run... or could it be the alternator or my small 24/36v 350w regulator?
Hey, if you're using 24v on the stator, try to use less than 7-8v on the field coil while running the brushless controller
Open it up.I got that one red wire that keeps getting it's self lost. Someone cut the connectors off and I am not sure the pinout on the wire on a 5 fet skinny red next to the resistor and caps.
Sir which mosfat can be used in place of Ru 75No8R
Just asking u have to remove the battery to charge it? Is there a way to plug to and charge it i mean charging port?
Can you measure the power and rpm of this motor at 48V? I wnat to convert my gasoline bike into electric using this motor.
What you have done with brush connection
How do you determine what size of controller to use for a specific alternator?
Nice
Being an automotive alternator, the field coil should happily run at 14.4 volts, which will give more power output as well. a couple 14.4v rc packs in parallel would energize that for a good while.
Rpms way too low with high coil voltage.
Is this alternater 12 v can it be for 48v controler
Where you bye this controller?
Can you send link?
Can this be posible long life motor and can run long drive?
Can I do the same with a normal three phase motor?
Thanks!
your welcome
on this example you are using 144 w on the motor 44 volts with a round 3 amps probably more depends on your controller.
Could you use the same controller if you wanted to use 12V vehicle batteries instead of the LiPos?
Yes you can
Contr
ollers have 5 volt sensor voltage built in- will this not power the field coil?
more then likely would not supply enough amps
Put the link to buy the 48 bolt batt ? Tanks
How much torque is it ? Thanks
Is it a sensored/sensorless controller?
5 volts actually works better on the field coil in my experience. An engineer friend at work suggested something about greater back emf being the reason why full 12v made it run worse.
I have found 12 volts to work real well for me, maybe i will do some experimenting with other voltages to see how it effects how it runs.
JUST GO MAKE IT yeah, I used a cheapo Chinese buck boost regulator to dial in a few voltages and now I'm running mine from an 80amp 20volt ESC from ElectriFly. The BEC output of the ESC plugs right into the field windings. The higher your RPM the more you notice a difference, I was thinking of maybe putting a "wing" of some kind inside the casing by the internal fan that cooled the diodes and using that to control a pot in a 555 to automatically give smaller pulses to the field windings at higher RPM. I've been told I have overly ambitious ideas sometimes though so we'll see. 😋
Forgot to say, great video. My stuff's stuck on instructables since I'm still getting used to videoing my projects.
That is pretty cool, glad you got it up and running.
for 48v or more, 12v on the field coils is great
for 36v or less, more than 7-8v on the field only weakens the motor
The 2 red and the white wire is white ground and red positive regulated? If i just want it to be on at full rpm what should i do. no regulation
Want to use 2 alternators one as a motor 2nd as as an alternator to charge a battery that powers an inverter
How many amps are you drawing at 48v?
Fellow, I just want to make one simple question. Why do we need a speed controller, when we can install a variable resistor? I ask you because I´m going to use a 12v 40 Ah AGM battery. My design is a pushcart, a 3rd wheel pushing my bike, with the brushless converted alternator attached with a chain drive to a small bicycle rear wheel to provide thrust.
Do I NEED a speed controller?.
Why do I need it?
You need the controller because it is 3 phase
How many hp this brushless alternator generates??
It is sensor less controller
Where it is available please inform me sir
شكرا
I have a alternator that has 6 pairs of wires, I wired it in what a delta configuration, but when I energize the rotor and turn up my speed controller the alternator just sits there and twitches making a high pitch whine like it wants to go but never spins. Any ideas? All the field coils ohm out nicely no shorts to the housing anywhere, the rotor ohm out at 5 ohms.
do you still need help?
@@foxxyytofficial I gave up on that one and threw it away, got my hands on a GM LS/Vortec Alternator that worked like a dream, that are already delta wired, :P Thank you though!
@@JamesRader do you have videos or pics?
can this run a outboard botom section and fo how long
How much of horse power it generates?
boss can u show us the wiring diagram in a one piece of paper? thank you
Why there is no need for hall sensors? How can it work without them?
Could we have a link to the one you brought as none say they are for sensorless.
it doesnt have to be sensorless
JUST GO MAKE IT so i dont have to worry about the hall effect sensor
no you do not
what type of controller did you use and where did you get from Rick
brushless sensorless controller for ebikes
aliexpress
Can u use it for a moto bike
On older alternators the field winding was fed through a small bulb in the dash of the car. Once the alt was generating the lamp went off. If you fed it from the 48V main battery through a suitable resistor, that would save having the need for a separate 12V supply.
An alternator has to get above 2100rpm before it comfortably powers the field coil. If this was powering a vehicle it would work on a steady long journey but not very efficient around town. Unless it was continually running then a clutch and gears would be needed.
So thinking along those lines, would it be a viable idea to feed the field from a nominal 12V source via a car dash-board generator bulb? That would provide enough initial current to initiate the field before the self-generation effect countered the supplied current, then the bulb would then go out.
Do you need the armature energized?
yes you do i put 12 volts to it
Can it be charging the battery at some time running alternator.
no
Will it work if esc is for brushed motors
no it will have to be a brushless esc
Won't that alternator blow the controller under load? It looks like it could draw way more than the 1kw limit of the controller.
yeah, some alternators can pull up to 3200W
What’s the highest voltage you can give that thing?
people normally puts up to 72v on these alternators
Hello and well don you make good job Pleace thell me its posiboll to run car althernator- sensorless motor with sensor controler .Because I want to buy a powerful controller but all are sensor, I also have a motor alternator with 36v 15amrera controller but it is weak for my bike Thank you in advance
you can install sensors
the youtuber Austiwawa have a quick math calculation that helps you to know where to put sensors
Small outboard motor?
Can you tell me. I have a alternator have 6 wires from windings. How to connect to controller. Help me to make connection.
do you have an email?
is there someone who have test effieiency of this motor (used from car lternator)
Can you couple another alternator on the other side or onto same shaft so you get power back. I've seen this being done on another channel. They harness the extra power through metal dc capacitors before going back to power the motor again. This also acts like a buffer to work nicely to charge battery.
i have no idea give it a try
You can get power back but you're better off just drawing from the battery.
you would be only dragging more weight and the energy recovered can be a lot less than you lose only making the second alternator spin
No no and no... There are always power losses, nothing is 100% efficient.
Maybe you can give the wiring diagram pls
About the power ... consider that they are asking how much power with out burning it
How would a 5k be better than a 10k pot? Would you explain that
the original throttles were 5k potentiometers
Mean the 3 batts
How to Hall sensor connection sir? 🙏😁
It,s Work without hall sensor ?🙏🙏 please give me solution
Just buy a controller that doesnt require hall sensors.
@@earnwithbots2783 eeem ok thanks sir
My order 48v 1500watt can work without hall sensor but start rotate not good🙏😁
alternator not hot?
to connect hall sensors you need to modify the alternator, in the site EndlessSphere the user Widodo put hall sensors on the alternator
Have you tried more voltage in the field coils?
more voltage in the field coils can make the current go up, make the field to oversaturate and make it overheat, the best answer to this "detail" is to adjust the voltage in the field coils, to get in safe levels
HEY! please check out Gerard Morin and htperdrive. i think you could help make his controller
No another controller you can use or it's the only one.
only BLDC controllers
Zoom in on a scale from closer
Bro my alternator has 8 cables, help me!
I dont now, its not possible send link in this channel.
I think, You need this:
Compatible Motors:
Only those 8 wires(3 phase-cables & 5 hall-cables) DC brushless motor that can work with this controller,
other brushless motors are not compatible.
Installation:
These controllers have 4 groups necessary cables(power cables, E-lock cables, Throttle-cables & Motor-phase cables),
when hook up these 4 groups cables, the E-bike can run normally.
Besides, these controllers have other optional functions, users can hook them up according to your applications.
Package Included:
1 X Brushless Motor Controller
More details of the controller would be less misleading to people, must have sensorless function in the controller or it will not run.
what horse power is
this specific model probably wasnt tested, but people tested one Denso alternator and it got 3,2kW max power
3200/735=4.35HP
Youre 1500 watt contrler the most youre gonna get is roughly 1.5 horse 750 watt per horse power but with frition losses and power consumed in feild winding about 1.5 horsepower but electric .otors are bery tourky and accelarate very fzst
Repeat after me... ALL (a very slight hesitation emphasis on the Ahl like pull) -tin, (another almost imperceptible hesitation) Ate-her (but no hesitation in between syllables) LOL! JK...but that's payback for saying it was an easy conversion and making 5 videos!!!
Convert it into an electric boat motor!
Especially in part one not going into depth
can you loose the back ground music is disturbing thank you
Sir please answer my question
whats your question?
alternator not very efficient as a motor but cheaper
too much talking.
thanks for watching
Man..., you are complicating the shit out of it, and spending 20, perhaps, 30 times more than you should. Just convert your alternator to 3 phase, and use an IRF Z44, the most 3 of them, with a PWM with enough amps.
the alternator is already 3-phase
brushless are 3-phase...
