Spindle motor rewind

Perhaps he meant not enough room to get the turns in. Anyway, they said it would be impossible - I guess they were just not interested. G.

I think you guess correctly, getting the turns in is not generally a problem, once you know the turns you have to decide on the wire dia that will fill the slots as much as possible, bigger is better but it depends on the practicalities of getting them in. It may be that the number of turns required reduces the dia of the wire enough to limit the current, and thus the power of the motor.

What is the current rating of the existing motors, may be cheaper to get a VFD with enough amps to drive them, you would be able to program it for the volts.

Be interesting to see Jonathan's winding solution.
