Question for the motor experts - winding?

[johnrobholmes]

It may be wave wound. If anything it may be a distributed winding, but it wouldn't be a derivative of LRK.

There are some pretty good pictures of a couple Plettys in this thread.

This appears to be a 1 turn winding. I can't make out the termination since I can't see the other end of the motor. Judging by the way it comes together, it appears to be some sort of Delta.

If I'm correct on the kv of the pletty max with fan, it's 3000kv?

This confirms that it must be a 1 turn to get that high of a kv with the large 4 pole stator.

Definately hand wound. As each set of strands is inserted through the opening, they took the time to slip protective sleeves onto each set of wires.

Machines don't do that.

The configuration should be easy to duplicate, but I wonder what the possibilities are? I have to get ready for work now, but I'll research this tonight.

One possibility. Lower the kv and use a single larger strand of high temperature wire for maybe 2 turns. 2200kv being the target maybe?

Single strand, single turn with a wye termination maybe?

Hmmm...........what is the diameter and length of the stator magnets?

i believe it`s 2 turn, but i could be mistaken...

Hey John,

Can you point me at some 4 pole winding patterns for a 12 pole stator field?

ABCABC is the only concentrated wind I know of for 4 pole/6 tooth. I don't think a 4/12 motor is a good combination for typical distributed winding.

This may help for the overlapped winding (wave type)

Wow, I need some Coffee. LOL

Thank you John. This is very helpful. A Wave Wind is an entirely different format altogether.

I'll continue researching in this direction.

It appears to me that Plettenberg, Neu, Medusa, and I'm sure Castle Monsters use this wind also.

I looks easy enough to follow the existing format to produce the same wind. But I wonder what the variations are?

I don't want to assume anything, but isn't this wind pulling on all 4 magnetic poles of the armature at the same time for each phase?

This is great. No wonder these motors are making so much power.

I called Plettenberg today and they told me that you have to pay 155€ for new windings for your Maxximum

Nuts!!!! I gues I made the right choice! Sike and I did a trade, so he gets to play with the plett, and I have more lipos to fool with!

[BL-Power]

Yeah, you did the right thing, 155€, that's nearly a new Neu 1515.

I hope sike will tell us if he did manage to rewind it.
