Frequently asked questions
What is an AC servo motor?
An AC servo motor is a permanent magnet synchronous motor with a feedback device such as an encoder or resolver, driven by a servo drive for precise position and speed control.
Which AC servo motor brands do you repair?
All leading brands, including Allen-Bradley, Siemens, Panasonic, Yaskawa, Mitsubishi, Omron, Bosch Rexroth, Kollmorgen and Fanuc.
Do you repair discontinued AC servo motors?
Yes. We repair legacy and discontinued models.
What causes an AC servo motor to fail?
Common causes are encoder or resolver failure, bearing wear, winding insulation breakdown, brake failure and contamination by oil or coolant.
How long does repair take?
Emergency same day, urgent 3 days and standard 7 days, depending on parts.
Do I need to replace the drive too?
Not necessarily. We test the motor and, if needed, the drive. See servo drive repair.
How do I send my motor?
