Short answer
Can a spindle motor be repaired?
Yes. Spindle motors and industrial AC and DC motors can usually be repaired or reconditioned, including new bearings, winding repair or rewinding, commutator and brush work on DC motors, and feedback repair. We test every motor before it ships back with a test report and a 12-month warranty.
