After frying my stator (as described here viewtopic.php?f=3&t=15095)
I have started playing With the idea of rewinding the stator myself. After a quick search both here and on Google I think it should be within reach.

Anyway, I found that the charging part of the stator has a somewhat non-symmetrical layout that had me puzzled. That is - it has 14 charging coils where I was expecting to find a factor of 3 number of coils. However the spacing was phase 1,2,3...1,2,3 and so on untill it ended with 1,2 making up a total of 14 coils. I discovered that the number of windings was approximately 40 for each coil and in 3 cases it was only 20 windings/turns on the coi. When I added them all up, I found that phase 1 and 3 had 160 turn totalt distributed through its coils, but phase 2 had 180!?

My initial thoughts was that the total number of windings should have been equal between all three phases, even if the layout is a non-symmetrical distribution.

I am therefore asking you all if I shuold leave it like this - or should I compensate when rewinding and loose 20 turns on phase 2 to make them all 160? Or is there some though behind these from the factory perhaps? Its beyound me for sure at this point, and I have no idea if it has been rewound before.
If anyone has any data to support the number of windings etc I would be pleased to hear it.

Thanks for reading

RM stator rewinds coils and are very good about technical questions like what you are asking. You might want to give them a call.
