Case Study: Indramat Servo Motor Repair

Indramat servo for blog

Successful Indramat servo motor repair

Repair Zone received an Indramat servo motor for repair, in which the customer did not provide details of any issues.  The first thing our technicians did was meg test the coils to make sure the motor wasn’t grounded.  Next, the brake torque was checked and  a failure occurred, it wouldn’t release.  This possibly needed replacement.

Jason then disassembled the entire unit, and checked the encoder to make sure it was viable and functioning correctly.  The encoder was checked on a testing stand and we found no issues going through its rotations.
