I've fried my first motor!
It's a "Voilamart" type rear hub motor going up a long hill with a heavy load. I'm running 52V with a 16Amp ebay controller.
I've managed to get the stator out of the rear hub and the magnets on the rotor are intact. The stator has several burnt looking poles. The motor still spun when I hit the throttle, but it's rough as guts and makes a strange noise. It seems I've created some kind of nasty electrical brake from all the shorted windings.
My question for ES: is it worth sourcing a new stator to put inside the rotor and wheel I already have? I'm struggling to find an exact match, "G‑M029" motor on aliexpress seems to be very close. The alternative is to buy a whole new motor, but this would cost more and require a wheel rebuild.
I'm considering one in following, and very little information is available unfortunately.

The motor I have has 46 magnets in rotor (27x13mm), 51 poles in the stator (27mm wide), stator diameter is 198mm.
If I get another stator with the same dimentions, what are the chances the clearances bearings etc. will be the same?
Thanks and regards from the land down under.
