A VFD will have an output with a nominal frequency from 0 to 500Hz for example, but the sine wave is created from square waves at around 10KHz which is why you hear the high pich whine from drives and the motor squirrel cage in the rotor and stator windings are designed around this high frequency inductance .

Another important difference with VFD rated motors is that at least one of the bearings will be insulated. VFDs can induce eddy currents that circulate longitudinally along the rotor and back thru the motor housing by way of the bearings. These eddy currents will burn little pits in the bearing balls/rollers (much worse with ball rolling elements due to the smaller contact area and thus higher current density) and races which cause the bearings to chew up their own guts, so to speak. The insulated bearings break the conduction path of these eddy currents and thus prevent such damage.
2.5 kw from a small stream 24/7 that is a lot of power ( 23 mega what hours 😳). All those net zero mp’s need to take note😳. There are tens of thousands of locations thst could use this type of technology never mind all the rivers. I guarantee if he had asked permission to do this there would have been a thousand reasons why he couldn’t do it. Love the self cleaning intake filter 👍
Great to see a different set up Kris 👌🏻 and good of you to help out , knowledge is POWER 😁, more so in your case 😉, great job 👏 well done that farmer for initial set up 👍🏻.
I was getting Kris withdrawals lately do I decided to go back and watch your old videos again ♥ what you have achieved in the last 5 years has been incredible and a true credit to you ! Love from Australia x
Thoroughly enjoyed watching that, thanks for sharing. 2.5kWh 24/7 is a phenomenal amount of power. The thing that always gets me is that if you could turn all of those 22,000kWh the farmers turbine creates every year into diesel, it would keep a HGV running for 8 x 8 hour days. The amount of energy we take from fossil fuels everyday blows my mind.
This is the stuff that originally brought me to your channel - I love the independence and the important knowledge related to these kind of projects! Not only that but you're like a frontliner for the fight against the insidious corporates that want us to lay down and be dumb and compliant. Keep it up Kris.
Kris brilliant video, loved seeing how the farmer managed so much from recycling 😮, looking forward to seeing the upgrade on your own hydro ,bringing both areas together ... just great, 😊
Good job on the farmer showing us this issue. It is the same in the US, we work with what we have at hand and new for vital needed parts. Glad the farmer had you to help with a bit of engineering. Good job to all.
If you have a VFD it converts the AC to DC and then back from DC to AC, so you can make the DC bus voltage higher and then drive a higher AC motor voltage, so this is why. You can get a higher power density in the motor if you can run it at a higher voltage. At work I do stuff with ~700V motors and design power electronics to drive them. Great to see what can be achieved with stuff to hand 😊
2.5KW 24/7/365 is awesome. My renewables only occur during the day and the excess dumped into batteries for overnight. I wish I had a little stream nearby....
This is the right sort of thinking in every way. The presenting style is perfect by being exact and to the point. This is especially noteworthy because clarity cuts through external noise and, inevitably, parts of such systems are noisy. The fact that noise and vibration at the turbine end was a concern is because these affects denote inefficiencies -- noise and vibration being users of energy and forms of energy. So much learned in 22 minutes is remarkable and the smile says it all.
Wow legendary flow rate, head, design, and to my surprise seeing such a successful induction motor. loved the spinning screen design too! so much epicness in this video much thanks to the farmer for allowing Kris to share this video!!!
Kris that was beyond excellent in all respects. Fantastic result 60KWh per day (for almost free) is a very useful contribution to the farm and the return on investment is absolutely bonkers. Just a few observations: when the turbine shroud is in place the chaotic splashing may be inducing additional drag, I think a revised nozzle aiming system may get the angle of incidence with spoons dialled in better. Hope to see more of this one.😀👍
Some optimisation should see that system produce another 20% easily. What a fantastic job he's done with whatever he could find, love the rotating debris screen.
Great video Kris. Just a thought, but maybe if you increased the size of the enclosure around the Pelton wheel there would be less chaotic/turbulent flow on the spoons. This can only be causing losses. There is much more flow now than when it was originally made for a 300W generator, and all of that "spent" water needs to get away from the wheel, not be thrashing around it. The very fact that it's pushing the perspex cover off shows the build up of pressure in there.
@@bartdepauw1156 Bart and Nick yes I agree. It is similar to windage losses in the crank case of an engine. Need to get the low velocity water spray away from the pelton wheel.
I was thinking, wouldn't it perhaps be better to have an enclosure consisting of 2 half cases, surrounding the spoons. Something that resembles a Turbocharger, so the nozzle stream is concentrated on the spoons
Chris Duncan's the one who needs a Knighthood; Numatic 250 still selling strong seldom breaks down 50 years on a fine example of British engineering (Known as Henry to most) Plenty of Dysons available at the refuse tip
so impressive. 2.5kw doesn't sound much at first (when you think vs a decent solar array) but when you consider that is 24/7 its a huge amount of power... love these videos Kris!
so nice to see that the UK allows small hydro projects like this without a mountain of red tape and gov. regulation expense as they do in canada and other countries. these things should be encouraged everywhere.
Its a lot easier if you are a farm as the planning rules are different and the max limit allowed is 2.5 kilowatt otherwise its back to the bs needed for power stations without some special exceptions
@@highlandrab19 in the UK i'm pretty sure that if your local water company finds out, then they will want their cut or you will have to cease and desist. I seem to rememeber an episode of Dick Strawbridges TV program where he did a small water hydro using a stream on his land and the water company magicaly appeared and demanded money with menaces.
A water abstraction licence is required from the Environment Agency in England. That can be difficult to get, not least because of the potential negative environmental impact the reduction of flow has on the ecology of the water course between the abstraction point and the point where the water is returned to the water course.
@@tonyb83 It's just that sort of BS that is working against a greener future. The hydro is not extracting the water like land irrigation does, it just uses it and puts it back again.
Plato: Necessity is the mother of invention. 6k power bill certainly focus the mind on the necessity; the invention, the fun part, using McGiver-like skills creating a wild ROI ratio. Kudos to Mr Farmer for being resourceful and you Kris for the fine tuning skills... really enjoyable vlog 🙂
This Project ist amazing. Have you ever tried to remove or enlarge the turbine enclosure? Looks like the off-flowing water spray of the turbine is braking the turbine spoons. Too small enclosures are a regular problem of pelton wheels. This is the reason, why pelton wheels of modern power stations have most of the time vertikal shafts and enclosures with a size of two to three times the wheel diameter, so the water can flow away without braking the wheel.
Great stuff! Loved this story, fantastic ingenuity from all involved :) Such a great solution with what would otherwise be categorized as junk, love it!
I like this kind of content. you should do more content per each video or 2 videos with extended footage. I really like listening to water draining as you work out the correct parameters. it is very relaxing.. I know sourcing a motor and installing new spoons may seem tedious but I would enjoy seeing you attach the things and of course using smooth tubing which you said you will do as well as wider tubing and a larger tanks or a second tank run in parallel output or y diverted will be fun to watch. Remember not all content needs to be educational. some of it can just be fun, including showing the fails and adjustments. I enjoy seeing how people adjust and solve their home made systems.
This is absolutely weird - I was laid awake at about 0400hrs today not able to sleep and for whatever reason thought of Kris and how I haven't seen any videos in my feed for ages - lo and behold here he is 😊
18:35 splash back might be backsiding the spoons just enough to be shy of a smooth 3Kw try a much larger shield such as a plastic drum fuel barrel and if the splash back is far enough away from the spoons then you only need a 30-50cm slit at the bottom to drain off in a smooth waterfall. a conical spiral propeller is what is used in hydroelectric dams that has a top down water flow to absorb as much energy from the water as possible going into a tube with slightly angled fins and more fin spiral widening out as it traverse the cone. but even more efficient is if you went to a funnel and then a cone with the 4Kw at the top funnel propeller and the reduced energy water falling onto a cone turbine running that other previous generator he has at the lower RPM could pick up an extra Kw of power on the secondary power transfer to the cone from the funnel. double dipping if you will.
Kris, always love watching your uploads. I have a stack of butterfly valves and PE fittings that are available if you want them. I can email you a picture if required. All free, shame to see them go for scrap. Keep up the great vids
Great video. I believe you can improve the generator output by reducing the size of the exciter capacitors. The original 60 microfarad caps might be just right. At optimum generator RPM the water from the jets should leave the pelton wheel at exactly 90 degrees. On this setup the water leaves angled back towards the jets, indicating the generator is running too slow. I ran a small house for 20 years with a small pelton wheel & car alternator, and found maximum power output occurred when I set the revs so that water came out at exactly 90 degrees.
In 2021 my wife and myself became motivated to leave our careers behind ( V mandates), sell our home In the city and move to our remote property with our young kids. We really had to build up our off grid electrical system. Initially with Solar and backed up with a petroleum generator. Great for much of the year but less satisfying in the winter when having to supplement with the generator. There is a small seasonal stream across the property, last year we tapped into it and put together a small hydroelectric system. The learning curve was quite steep, however, by the late winter we had it running almost trouble free. A very small flow and not much head, but still a steady 5 KWhs per day into the lithium battery bank. It greatly reduced the use of the generator. This year we added another 43 KWHs of lithium battery storage and bought a pallet of 36 410watt solar panels (almost 15 KW). We’ve added heat pumps to the equation and even a freeze dryer (my wife’s request). Although feeling a little behind on getting everything up and running before the fall rains come, I’m actually looking forward to seeing how it all goes. Great video guys! I love to see I’m not the only one who is just a bit nuts :)
@@McDaniel77 I have considered it and regularly get asked this question. My answer is multi factorial. My biggest reason is that wife and I are very private and don’t really like putting ourselves out there for criticism in a public forum (like social media). The number 2 reason has to do with how I value time and where I prioritize my effort. We tend to spend our time working on our homestead and raising the kids rather than getting good at being a media content producer. There is more, but these are the top reasons.
i have a 2kW (electric imput) heat pump and 9kW solar panels on roof in hungary. i don't have a single battery, but the heat pump pump heat into floor heating system and when the temperature reach 25C inside start heating a 3m3 buffer watertank. the 9kW solar array able to provide enough energy even at november-december to keep my house warm and at sumer cool down my flat for free and the extra electricity feed back to network. btw i pretty lucky because this was not cost too much for me, because the green madness of eu we got a huge donations to put solar cells to roof.
@@makoado6010 Great. Nowadays solar cells are very cheap, for 1 kWp it's roughly 300 Euro including mounting. It's only expensive if you need professional service for installation.

Gosh Mate - your knowledge is impressive!!! This is what the 3rd world countries need!! Mate lots of countries around the world desperately need your skill. Thanks 🙏 for sharing.
It sounds like the motor you have is specifically designed for use with a Variable Frequency Drive (VFD). Motors that are labeled for VFD use are built with certain characteristics that allow them to be efficiently controlled by varying the frequency and voltage of the electrical supply. This allows for precise speed and torque control. Using a motor that is meant for VFD applications in power generation might present some challenges because: 1. **VFD-Specific Design:** Motors designed for VFD use often rely on the controlled and variable supply that the VFD provides. If you are trying to generate power with it (e.g., by spinning it to generate electricity), the motor may not be optimized to generate a stable current in this mode because it's not intended to function as a generator without a specialized setup. 2. **Winding Configuration:** Motors for VFDs might have different winding configurations or insulation systems that are optimized for variable frequency operation rather than the fixed-frequency generation typically expected from a generator. 3. **Electronic Compatibility:** The motor may have internal electronics that work best with a VFD and may not function properly or produce electricity in a generator setup. To use a motor for power generation, you typically want one that is designed as a generator or an alternator. If your motor is only designed for use with a VFD, you might have difficulty getting it to generate usable power efficiently. You might want to consult the manufacturer’s specifications to confirm if the motor can be repurposed for power generation, but generally, you would need an alternator or a motor that is known to work in a generator mode for this application.
Really interesting video. I think that the previous comment about variable speed machines needing a separate fan is correct. Also VFD driven machines need additional insulation in the windings to cope with the high voltage spikes associated with the square waves from the VFD.
I am a big fan of repurposing what you have to make something happen, it usually involves more work and maybe time, yet the end results are worth it, plus you get a greater understanding of how you achieve your end results.
Yay More Kris :) love these videos constantly waiting for the next and the next I swear I've gone through all the vids on the account more than a few times lmao

I guarantee if he had asked permission to do this there would have been a thousand reasons why he couldn’t do it. Love the self cleaning intake filter 👍
My thoughts exactly, so much rain and running water in this country. Have wondered for years how is it not utilised in this way?
23 MWh, how do you come up with that number?

Your knowledge on small-scale hydro is valuable! Love to see water powering small farms and have less/no reliance on grid power 💸
Good to see you smiling like that! The happy hydro face makes me smile as well! Thanks Kris
Great to see a different set up Kris 👌🏻 and good of you to help out , knowledge is POWER 😁, more so in your case 😉, great job 👏 well done that farmer for initial set up 👍🏻.
This was right in your "wheelhouse" Kris. Your enthusiasm was palpable. Nicely done.
Fascinating! Juggling all of the many variables to tweak output at the motor takes the kind of experience Kris Harbour brings to the table!
4 minutes and I am loving the story already. I really like the background of how you/he came to this
I was getting Kris withdrawals lately do I decided to go back and watch your old videos again ♥ what you have achieved in the last 5 years has been incredible and a true credit to you ! Love from Australia x
Thoroughly enjoyed watching that, thanks for sharing.
2.5kWh 24/7 is a phenomenal amount of power. The thing that always gets me is that if you could turn all of those 22,000kWh the farmers turbine creates every year into diesel, it would keep a HGV running for 8 x 8 hour days.
The amount of energy we take from fossil fuels everyday blows my mind.
This is the stuff that originally brought me to your channel - I love the independence and the important knowledge related to these kind of projects! Not only that but you're like a frontliner for the fight against the insidious corporates that want us to lay down and be dumb and compliant. Keep it up Kris.
It's just absolutely incredible what you are doing. People like you could give this country a second renaissance if only we didn't get in the way.

Kris brilliant video, loved seeing how the farmer managed so much from recycling 😮, looking forward to seeing the upgrade on your own hydro ,bringing both areas together ... just great, 😊
Great video. I’m glad you are continuing with new jobs, and helping people at all stages of involvement in their projects. Good work!
Good job on the farmer showing us this issue. It is the same in the US, we work with what we have at hand and new for vital needed parts. Glad the farmer had you to help with a bit of engineering. Good job to all.
If you have a VFD it converts the AC to DC and then back from DC to AC, so you can make the DC bus voltage higher and then drive a higher AC motor voltage, so this is why. You can get a higher power density in the motor if you can run it at a higher voltage. At work I do stuff with ~700V motors and design power electronics to drive them.
Great to see what can be achieved with stuff to hand 😊
What does VFD stand for?
A Voltage Fiddling Device?
Variable frequency drive
You meant AC to DC and then back FROM DC to AC? I think you made a typo error ....... or perhaps I'm too thick to understand?
@@nickwinn7812 yeah good spot, edited. For some reason the keyboard on my tablet is really dumb
@@gavster89 I assume when using a VFD you cannot do a proper grid tie and can only run independent 3 phase motor loads?
I could watch this all day, I don’t know why but you light a spark in me your knowledge is incredible thank you Kris 😇
2.5KW 24/7/365 is awesome. My renewables only occur during the day and the excess dumped into batteries for overnight. I wish I had a little stream nearby....
This is the right sort of thinking in every way.
The presenting style is perfect by being exact and to the point. This is especially noteworthy because clarity cuts through external noise and, inevitably, parts of such systems are noisy.
The fact that noise and vibration at the turbine end was a concern is because these affects denote inefficiencies -- noise and vibration being users of energy and forms of energy.
So much learned in 22 minutes is remarkable and the smile says it all.
Wow legendary flow rate, head, design, and to my surprise seeing such a successful induction motor. loved the spinning screen design too! so much epicness in this video much thanks to the farmer for allowing Kris to share this video!!!
Great to see your spirts have been lifted, you were buzzin about this topic. Cheers for another insightful video👍
Kris that was beyond excellent in all respects. Fantastic result 60KWh per day (for almost free) is a very useful contribution to the farm and the return on investment is absolutely bonkers. Just a few observations: when the turbine shroud is in place the chaotic splashing may be inducing additional drag, I think a revised nozzle aiming system may get the angle of incidence with spoons dialled in better. Hope to see more of this one.😀👍
Some optimisation should see that system produce another 20% easily.
What a fantastic job he's done with whatever he could find, love the rotating debris screen.
Great video Kris. Just a thought, but maybe if you increased the size of the enclosure around the Pelton wheel there would be less chaotic/turbulent flow on the spoons. This can only be causing losses. There is much more flow now than when it was originally made for a 300W generator, and all of that "spent" water needs to get away from the wheel, not be thrashing around it. The very fact that it's pushing the perspex cover off shows the build up of pressure in there.
I'm having the same thought. Wondering how many hundreds Watt it will win.
@@bartdepauw1156 Bart and Nick yes I agree. It is similar to windage losses in the crank case of an engine. Need to get the low velocity water spray away from the pelton wheel.
I thought the same thing, back pressure essentially on the wheel. Some separator plates and better direction of outflow will help a lot.😊
I was thinking, wouldn't it perhaps be better to have an enclosure consisting of 2 half cases, surrounding the spoons. Something that resembles a Turbocharger, so the nozzle stream is concentrated on the spoons
@tjordulf yes something like a centrifugalpumps impeller on each side making use of the wasted/spashing water
I personally think you are making more of a contribution to society than Sir Dyson with all his vacuum cleaners. Arise Sir Kris.

Kris is seriously my spirit animal. His approach to providing solutions with such enthusiasm is an inspiration to me.
You’re a really inspirational guy, making me think hard about how I can create a hydropower system on my property 👍
so impressive. 2.5kw doesn't sound much at first (when you think vs a decent solar array) but when you consider that is 24/7 its a huge amount of power... love these videos Kris!
Really interesting video and set up. Massive win for practicality, resourcefulness and upcycling. Quality stuff! Mad respect to both of you.
Incredible project, fantastic content. Thanks for sharing it, Kris.
so nice to see that the UK allows small hydro projects like this without a mountain of red tape and gov. regulation expense as they do in canada and other countries. these things should be encouraged everywhere.
Its a lot easier if you are a farm as the planning rules are different and the max limit allowed is 2.5 kilowatt otherwise its back to the bs needed for power stations without some special exceptions
The only permit anyone really needs is stealth.
@@highlandrab19 in the UK i'm pretty sure that if your local water company finds out, then they will want their cut or you will have to cease and desist.
I seem to rememeber an episode of Dick Strawbridges TV program where he did a small water hydro using a stream on his land and the water company magicaly appeared and demanded money with menaces.
A water abstraction licence is required from the Environment Agency in England. That can be difficult to get, not least because of the potential negative environmental impact the reduction of flow has on the ecology of the water course between the abstraction point and the point where the water is returned to the water course.
@@tonyb83 It's just that sort of BS that is working against a greener future. The hydro is not extracting the water like land irrigation does, it just uses it and puts it back again.
Plato: Necessity is the mother of invention. 6k power bill certainly focus the mind on the necessity; the invention, the fun part, using McGiver-like skills creating a wild ROI ratio. Kudos to Mr Farmer for being resourceful and you Kris for the fine tuning skills... really enjoyable vlog 🙂
This Project ist amazing. Have you ever tried to remove or enlarge the turbine enclosure? Looks like the off-flowing water spray of the turbine is braking the turbine spoons. Too small enclosures are a regular problem of pelton wheels. This is the reason, why pelton wheels of modern power stations have most of the time vertikal shafts and enclosures with a size of two to three times the wheel diameter, so the water can flow away without braking the wheel.
Great stuff! Loved this story, fantastic ingenuity from all involved :) Such a great solution with what would otherwise be categorized as junk, love it!
From 0.3 to 2.5 kW is a great achievement. And the noise reduction will make those cows happy! 😂 Thanks for sharing!
The intake screen is fantastic. I have never thought of or have seen that design. All in all great project. Thanks for the view.
I like this kind of content. you should do more content per each video or 2 videos with extended footage. I really like listening to water draining as you work out the correct parameters. it is very relaxing.. I know sourcing a motor and installing new spoons may seem tedious but I would enjoy seeing you attach the things and of course using smooth tubing which you said you will do as well as wider tubing and a larger tanks or a second tank run in parallel output or y diverted will be fun to watch. Remember not all content needs to be educational. some of it can just be fun, including showing the fails and adjustments. I enjoy seeing how people adjust and solve their home made systems.
Lovely project making use of what you got well done farmer and Kris...
Hi 👋🏻 Kris. How lovely seeing how excited you were working on the farmers hydroelectric system 👍🏻 Love watching your videos keep them up matey 😊
Where in the world is this blessed paradise. Plenty of water. One will never starved here.
Been a while since I visited your channel but I was watching back when you installed your current leaf screen at the intake. Your mind is amazing!
Great to see the old farmer getting things done with bailing wire and scraps...
Always good to be self sufficient
Never seen Rotary based filter before that was pretty interesting 13:00
What a sick setup that is! Loved the intake wheel!
This is absolutely weird - I was laid awake at about 0400hrs today not able to sleep and for whatever reason thought of Kris and how I haven't seen any videos in my feed for ages - lo and behold here he is 😊
18:35 splash back might be backsiding the spoons just enough to be shy of a smooth 3Kw try a much larger shield such as a plastic drum fuel barrel and if the splash back is far enough away from the spoons then you only need a 30-50cm slit at the bottom to drain off in a smooth waterfall. a conical spiral propeller is what is used in hydroelectric dams that has a top down water flow to absorb as much energy from the water as possible going into a tube with slightly angled fins and more fin spiral widening out as it traverse the cone. but even more efficient is if you went to a funnel and then a cone with the 4Kw at the top funnel propeller and the reduced energy water falling onto a cone turbine running that other previous generator he has at the lower RPM could pick up an extra Kw of power on the secondary power transfer to the cone from the funnel. double dipping if you will.
Kris, always love watching your uploads. I have a stack of butterfly valves and PE fittings that are available if you want them. I can email you a picture if required. All free, shame to see them go for scrap.
Keep up the great vids
Great video. I believe you can improve the generator output by reducing the size of the exciter capacitors. The original 60 microfarad caps might be just right. At optimum generator RPM the water from the jets should leave the pelton wheel at exactly 90 degrees. On this setup the water leaves angled back towards the jets, indicating the generator is running too slow. I ran a small house for 20 years with a small pelton wheel & car alternator, and found maximum power output occurred when I set the revs so that water came out at exactly 90 degrees.
Excellent system for mostly scrap! Inspirational! Great video.
In 2021 my wife and myself became motivated to leave our careers behind ( V mandates), sell our home In the city and move to our remote property with our young kids.
We really had to build up our off grid electrical system. Initially with Solar and backed up with a petroleum generator. Great for much of the year but less satisfying in the winter when having to supplement with the generator. There is a small seasonal stream across the property, last year we tapped into it and put together a small hydroelectric system. The learning curve was quite steep, however, by the late winter we had it running almost trouble free. A very small flow and not much head, but still a steady 5 KWhs per day into the lithium battery bank. It greatly reduced the use of the generator.
This year we added another 43 KWHs of lithium battery storage and bought a pallet of 36 410watt solar panels (almost 15 KW). We’ve added heat pumps to the equation and even a freeze dryer (my wife’s request).
Although feeling a little behind on getting everything up and running before the fall rains come, I’m actually looking forward to seeing how it all goes.
Great video guys! I love to see I’m not the only one who is just a bit nuts :)
Did you consider a documentary of your energy systems?
@@McDaniel77 I have considered it and regularly get asked this question. My answer is multi factorial. My biggest reason is that wife and I are very private and don’t really like putting ourselves out there for criticism in a public forum (like social media). The number 2 reason has to do with how I value time and where I prioritize my effort. We tend to spend our time working on our homestead and raising the kids rather than getting good at being a media content producer. There is more, but these are the top reasons.
i have a 2kW (electric imput) heat pump and 9kW solar panels on roof in hungary. i don't have a single battery, but the heat pump pump heat into floor heating system and when the temperature reach 25C inside start heating a 3m3 buffer watertank. the 9kW solar array able to provide enough energy even at november-december to keep my house warm and at sumer cool down my flat for free and the extra electricity feed back to network. btw i pretty lucky because this was not cost too much for me, because the green madness of eu we got a huge donations to put solar cells to roof.
@@makoado6010 Great. Nowadays solar cells are very cheap, for 1 kWp it's roughly 300 Euro including mounting. It's only expensive if you need professional service for installation.

It sounds like the motor you have is specifically designed for use with a Variable Frequency Drive (VFD). Motors that are labeled for VFD use are built with certain characteristics that allow them to be efficiently controlled by varying the frequency and voltage of the electrical supply. This allows for precise speed and torque control.
Using a motor that is meant for VFD applications in power generation might present some challenges because:
1. **VFD-Specific Design:** Motors designed for VFD use often rely on the controlled and variable supply that the VFD provides. If you are trying to generate power with it (e.g., by spinning it to generate electricity), the motor may not be optimized to generate a stable current in this mode because it's not intended to function as a generator without a specialized setup.
2. **Winding Configuration:** Motors for VFDs might have different winding configurations or insulation systems that are optimized for variable frequency operation rather than the fixed-frequency generation typically expected from a generator.
3. **Electronic Compatibility:** The motor may have internal electronics that work best with a VFD and may not function properly or produce electricity in a generator setup.
To use a motor for power generation, you typically want one that is designed as a generator or an alternator. If your motor is only designed for use with a VFD, you might have difficulty getting it to generate usable power efficiently.
You might want to consult the manufacturer’s specifications to confirm if the motor can be repurposed for power generation, but generally, you would need an alternator or a motor that is known to work in a generator mode for this application.
Wish you were my nabhior, you are so smart and industrious Kris and thrifty working with what you can find laying around property's. Love you channel
Another magic video just perfect 👍
Really interesting video. I think that the previous comment about variable speed machines needing a separate fan is correct. Also VFD driven machines need additional insulation in the windings to cope with the high voltage spikes associated with the square waves from the VFD.
Thank you. I learnt a lot from this video.
I am a big fan of repurposing what you have to make something happen, it usually involves more work and maybe time, yet the end results are worth it, plus you get a greater understanding of how you achieve your end results.
That system is a thing of beauty 🙂
Stuff of legends and how the universe was created, keep it up Chris !
I'd love you to write a book all about about your hydro systems and how to build them

Kris called it 9 years ago go back and watch his second video whenever he was just a kid I think it’s called “Why go off grid” he was right about everything 😊
Why isn’t it sensible to run his hydro in summertime?
We have so many private photovoltaic installations that the local electricity company has to switch on the metal halide street lights to keep the grid stable.
The end customers don‘t get paid for using electricity either 😅
Chris, this subject is fascinating always happy to watch your work! If I only had a year round creek with 30' of drop on my back forty I'd be gettin after this. Excellent and thanks Chris!
