I began winding the motor Friday evening (before leaving for Maker Faire early Saturday). Now, I had said before that I would be winding the motor fully interleaved, that is: A-b-C-a-B-c-a-B-c-A-b-C; But that causes a mess of wire terminations interleaved with each other too. I’m electing to do it instead as. AabBCc—— ——aABbcCread more

But, rather than wind Aa and jump across the stator to aA, I'm splitting it into two half motors: [AabBCc] and [aABbcC] which will then be connected in parallel "Y's" for twice the current. Turns out this is the proper way to split a dLRK winding into two parallel motors - you can't just wind two interleaved LRKs. (It took us some time ...read more

DELTA vs WYE (STAR) Termination. Theoretically, the ratio between Delta and Wye is 1.732 (square root of 3). However, in practise this number is closer to 1.8. Therefore, a motor with a given number of turns, terminated WYE, would yield ~1.8 times more Kt (torque per amp) than a similarly wound motor that is terminated Delta, while the Kv (RPM/volt) would be ~1.8 times lower.read more
