Has anyone successfully done a rewind on a Mobilaire hex motor?  I thought I could do mine, but could not get it to unwind without cutting the wire on the worst coil.  Help!

after further searching, found the patent on the motor by Gustav Koch, 2,728,038 that has the schematic for the motor.  Now I just need to trace my wiring to make certain that it matches this, and dissect the coils to try to get the wire counts.  whew.  what fun!

it took me 2 1/2 times to get it to work and not burn out!  Right now it's running fine, quite fast on high, moderately slow on low, the temp on the hottest coil is 150F on high speed and 205F on low, not bad, but if I did it over, I would cut down on the number of secondary windings a little. Whew!

Very glad you got it going! 

Would love to see pictures of your stator. I've only done one wind and hope to learn to do more complex motors in the future.

I could send the completed, mounted in fan photo, if you want it.
I took extra care on the second rewind:  I used nomex pieces to wrap around the fused field connections after shrink wrapping them too then stuck them between the coils.  I used some cut pieces of nomex to put under the wire leads and above the once laced coils to prevent shorts there.  Otherwise, I think a "normal" wind.
