170 watts in - 1600 watts out - looped - Very impressive build and video

Hi Everyone
Pierre wrote me private message, and gave me the "magic numbers" how the stator windings connect!! Maybe he likes me because I am a konehead haha I don't know but here are the numbers
in the schematic jpg
I also drew up too of how they connect. The colored pattern is red black blue green yellow
Note how at 31 and 32 poles the pattern becomes "red red" as there seems to be some sort of 35 vs 36 situation going on and one extra pole appears....anyways please study this as it is direct from Pierre.
Also note he said there are 6 poles in the rotating filed, and these are NSNSNS....

hi all
looking at the pattern of stator connects, seems to be 6 poles pulsed, then one blank pole, then another 6, then another blank pole and another 6 around the stators like that......so makes some sense with separation of N and S of NSNSNS pattern of pulsed stators being only one blank pole...count out the pattern you see what I mean...Also you see for example 7 "red to red" connections going around stator so here again is an odd vs even situation perhaps these magic numbers he gave is reason for no lenz law appearing I don't know

Hi Konehead,

Pretty much what I had deduced over the last few days. Thanks for getting the information.

If I can find a 36 slot stator DWG file I will also model this in FEMM.

I think we have already seen from the simulation that PmgR has done, that when the stator coil flux is out of alignment with the rotor, i.e.the flux enters at an angle, the counter flux due to the load  is directed mainly straight into the stator, which indicates that there will be a phase difference between the energizing flux and the counter flux. This implies a lower level of cancellation due to CEMF.

I have a burnt out 3 phase 2 pole generator coming my way next week, so I will also be able to replicate exactly, (if the stator has 36 slots!).

Regards

I'm done. Thanks

Thanks for sharing Konehead

From the below pic I took of Pierre's first video you can see the motor stator part number: 36A01W462
Which is from a Baldor 5HP 2850 RPM 50Hz 3Phase Motor, Volts 208/360/415, AMPs 13.2/7.6/6

Question to anyone that knows: has Pierre mention anywhere if he rewound his stator?
