- Wiring the two washing machine stators in Delta, one factory 1 x 14C and the other in the 2 x 7C configuration.
Delta means the 3 coils are connected adjacently - so the end of phase 1 connects to start of phase 2, end of phase 2 connects to start of phase 3, and the end of phase 3 connects to the start of phase 1.
This is simple to do on factory stators, but becomes a little more complex when wiring down the stator - such as into 2 x 7C configuration.
Usually delta is reserved for higher RPM motors and generators, but I thought it would be interesting to see the results in a lower speed turbine.
Both stators seemed to work good after the wiring, however one had more resistance, which I'm not sure what could be causing it (putting energy into itself). Might be something to do with removing a turn from 1 coil in each phase? I will hope to find out soon.
I am currently working on getting the blades mounted and waiting for some wind for its first official test :) - Jak na to + styl
Nice work Stefan, be great to see the end product up and running 👍🏽
Excellent work my friend, and also appreciated- have a happy day
That would be great for a vertical wind turbine
Very interested video
Can connect same connection for 36 pole .?
Ok felicitări ❤❤
Thats awesome
good idea
Can you please tell me if 42 poles are the largest motors made ??? The wire are copper correct ??? Thanks
42 poles from these particular Fisher and Paykel brand washing machines. They later switched to 36 pole motors.
All the 42 pole motors were enamelled copper wound. Some 36 pole motors are aluminium wound which came with a stronger magnetic rotor.
Cheers
Thanks for the information Stefan. Would you know if larger than 42 poles motors were made and used Sir ? I am trying to get myself started with this project. Cold weather is coming with time on my hands Stefan. Good day too. vf😀😀😀😀@@stefanstoove9254
All good. I am not sure about larger motors. Maybe LG, I think they had a smaller number of poles on their direct drive motor. You can make do with these Fisher and Paykel generator sets for most applications. You can also run these back to back for more generation capacity. If going larger, I would suggest looking at investing into a commercial generator @victoryfirst2878 Cheers
Thank you for the information Stefan. @@stefanstoove9254
I want to do double motor. Wire both in 12 volt then series to 24 or both 24v? I don't think one rotor is enough....
24v and 2 running in parallel would be my suggestion, as it provides redundancy if one fails. Cheers
Good evening, how many amps I can benefit from this engine while extracting a current of 12 volts
Current is determined by many factors, however it looks the max current 1x14C in Delta is around 2.8A and 2x7C in Delta was less than 2A (but I would've guessed 3A + so might be a problem with wiring).
Cheers.
@@stefanstoove9254 This amp has a slow rotating speed, what if we rotated it at a high speed
I think the max current I found will be fairly close to the saturation point where the stator cannot put out any more current than determined by windings, inductance's and magnetic field strength, etc.
From my experience, you will get more voltage at higher RPM but current will curve off and maximise. But I could be wrong.
Thanks
Here's an interesting image which might explain it better:

Good evening dear, is it possible to send your email address to communicate so that I can send you a picture of the delivery and how I work to rotate the magnet? Thank you for the response
Wow stonks
Can you re-wire the units with aluminium wires?? I have just received one with aluminium wiring, thanks.
Yes it's possible, but not through soldering the aluminium as it's a really difficult. Try using crimp connectors over the aluminium wires, it sounds like it could work quite well.
Another point, Aluminium generators are typically not recommended for use in areas that have a lot of moisture from what I've heard.
Thanks
@@stefanstoove9254 Thanks man really appreciate the help , I'm working on a dual rotor wind turbine chain driven running a 48 volt ebike motor check out my channel if you get a minute, Thanks again !!
I have used crimp on connectors on an aluminum stator with success....i didn't use it as a generator though, only as a drive motor for another project. However, I did find out that a copper stator performed noticeably better than the aluminum....i wasn't sure if it was the crimp connectors or the different metal that made the difference
@@rusty9973 Aluminium has 61% the conductivity of copper so naturally will be less powerful in an electric motor, but still a very cost effective option for manufacturers to take.
That's awesome to hear it worked well for you with crimps for rewiring. Did you take the full parallel coils route for running on lower voltage? (48V ~ 1000RPM)
Cheers!
@@stefanstoove9254 At the moment, the stator is wired in Delta and it is running on a cheap Chinese VFD. I am pleasantly surprised with the performance. In the past I had it wired all 14 parallel and used a 60 volt brushless ebike controller to drive it
Do you know why it is so hard to run it? Because the coils has metal core
Not sure exactly? Cheers
Muito bom amigo
Obrigado!
are you wired up for a/c or d/c ?
These generators produce AC regardless of these wiring patterns. These can be rectified to DC from there on.
Cheers
First one seem to turn easier and produced more watts 31 volts and 2.5 amps (I know it was higher but easier math) 77.5 watts not bad at that rpm.
Yep, I have to say I am always impressed - they are decent generators.
I would've thought in Delta this would be more difficult to produce the same power at low RPM.
The 2nd stator I think there could be an issue with the windings - theoretically it should be more than the first stators current (2.8A I think).
Thanks
I would suggest you switch to 7x2C. With 1x14C or 2x7C your generator will get even harder to turn when a load is connected. Meanwhile for your water wheel why don’t you use 14x1C after all you only need 12V.
Yeah, those wirings would be ideal. I was going to experiment running as a low RPM generator to see the kind of results.
Absolutely correct on using a higher gear ratio for more speed with 14 x 1C - given enough input torque.
In the waterwheel, we didn't really understand at the time, but would most likely have gone back and changed it to this configuration.
Yeah 7 x 2C is usually best but I think needs around 150RPM which might be difficult with such a large blade diameter.
Thanks.
@@stefanstoove9254 Can you recommend a good tutorial for a noobey to learn these configuration terms? Also, what have you found to be the best configuration for single phase 110AC output? My power company has been harassing me to let them swap my meter out for one of those {insert long string of expletives} 5G "smart meters." When "push comes to shove," I want to be able to tell them exactly where they can shove their piece of crap... Plus, I can foresee electric prices skyrocketing in the very near future. I'm a disabled senior on a subsistence level income; so, combined with the projected 76% jump in grocery prices within the next 6 months, I'd probably be without electricity, even if they weren't already hassling me to let them come on my property to change out the meter... For the past few months, I've been watching as many of these videos as I can; &, scrounging/tearing apart as many dead appliances as I can get my hands on. I've got a strong feeling that I'm already "behind the curve" of where I need to be. I live on my own 7 acres in a rural area; so, I don't have to worry about any "code enforcement" hassles; but, I do want to do things safely. Also, I don't want to fry anything I've been able to come up with so far.
Early on, I'd spent several hours over to backshed, trying to find the answers I need about doing the rewiring; but, I didn't find anything even close to what you had a shot of early in this video. I'm sort of wondering if it might be that I'm not seeing the link on their page because of the way I need to have my computer monitor set up, due to some vision issues. If you could post a link for that chart, that might be a big help; esp., if it's clearly explained over there. :)
EDIT: I did finally find that backshed page (it was labeled as "F&P motors," which I've since learned was the original ~ possibly Australian ~ version of these "smart drive" motors); &, it was under their "wind" section. I've only recently even considered using 1 or 2 of these with wind; since, I'd really prefer something more portable & less noticeable ~ such as turning it using a horizontal shaft motor, converted to run on HHO... I'd looked into wind& solar close to 20 years ago; but, dismissed them as not being cost effective for someone on a (broken) shoestring budget. I hadn't really given much more thought to anything more than just playing around with magnets to build a magnetic induction water heater, UNTIL these past few months...

Hi there,
Yes I agree there are plenty of good informative sources online and a great resource for learning, but also a lot of misleading information around too which I've fallen into many times.
I struggled trying to figure how elecricity and generators worked earlier on, and spent countless hours watching others experiences, which I've learnt a lot from. I am now studying mechanical engineering :)
Yes there is a ton of valuable information on the backshed.com under the forums, some very clever people working on shaping backyard science and energy technology.
Let me know your contact detail and I am more than happy to share my experiences so far.
Apologies have only seen your comment now, was under review for some reasons?
Kind Regards,
Stefan
hi, it seems easy but no explanation of what wires a diagram might help.
Anyone here knows where the best place to buy copper wire in the US?
I don’t have confidence to buy from Alibaba.
Any electrical supply stores - Aliexpress, or eBay for the odd bits and pieces. I've stripped wire off of existing motors and reused.
Cheers
Please upload a full video 😮,

👍👍👍
How many turns per slot
I can't remember exactly. Might've been in the 100-200 turns range. Cheers

The second one is half burnt out I think
Such a complicated process yet nobody can make a good video of it. It's always these types of videos with very little explaination.
Just follow the picture.
You can be the first!!
