Servo MOTOR TESTING

It is very important that a Servo Motor is tested before and after repair. We carefully test the motor winding for imbalance in the internal magnet circuit and the motor winding for imbalance in the insulation between turns, phases and to earth, we have seen thousands of types of servo motors. Encoder and resolver testing is an important part of carrying out a check and report.

The most common faults we find are bearings and housings worn, encoders damaged by worn bearings and sealing of the servo motor inadequate.
