Dynamic Testing – Servo Motor Repair
Upon arrival, servo motors are back driven before any screw or bolt is removed. We run a variety of tests on the servo motor and associated feedback devices before the servo motor repair process even begins.
Servo Motor Alignment Testing
Every AC servo motor will have their alignment checked and recorded both statically and dynamically before being disassembled. This procedure ensures correct alignment when the servo motor is repaired and rebuilt. Correct servo motor alignment is important as bad alignment will cause the servo motor to not run correctly, if it runs at all.
We test windings at full nameplate voltage and current to be sure they will not break down under load. All windings are washed, baked, meggered and surge tested.
We Repair Over 100 Servo Motor Manufacturers
Magnet Testing of Servo Motors
Magnet strength is tested to insure you are getting the proper torque out of your servo motor. If your servo motor is determined to have bad magnets we can replace broken magnets and re-magnetize magnets which have lost their strength during the servo motor repair process.
With the use of oscilloscopes and torque meters, we check the wave pattern of the servo motor winding and the torque output to insure the servo motor will deliver during operation back at your business.
Final Testing of Servo Motor
Final servo motor repair testing involves a second round of all the initial tests to ensure the problem is fixed. All servo motors are run on matching factory drives or manufactured drives that have the correct parameters for the servo motor and feedback configuration. This ensures your servo motor is repaired correctly and will perform properly.
