motor repair

Hi all,

The spindle motor on my machine lost a magnet and jammed the motor.
This is a small spindle motor and was wondering if anyone knew of any
shops that repair motors ?

Since it is so small, I'm reluctant to take it to one of the
commercial shops that do big three phase motors.

Any suggestions ?

BTW, this is a high quality motor set into a custome housing. Simple
replacement will be at least $500.00 so repair would be desirable.
