Does your shop rely on AC/DC servo motor technology to keep production moving? If so, you know that a poorly performing servo motor can bring production to a halt, resulting in costly downtime. PSI Repair Services has specialized in servo motor repairs and testing for over 40 years. As an authority on understanding servo motor performance, PSI knows there are four golden rules to successful servo motor repairs. They are:

1. High voltage surge testing 
2. Stressing the motor windings to check for breakdown under high voltage
3. Proper alignment of the feedback to the motor poles
4. Complete system closed-loop testing

PSI analyzes and evaluates motors for vibration, temperature fluctuations, bore run-out and, of course, electronic integrity. Drives are repaired to OEM specifications and are load tested to check for proper voltage and current characteristics. To complete the repair cycle, PSI’s trained technicians perform bench tests, as well as extensive system/closed-loop testing, to ensure the performance of each servo motor we service.
