Fuji Electric servo motor repair
Star Automations repairs Fuji Electric servo motors, including GYS and GYB series motors. The motor is inspected, the failed parts are repaired or replaced, the encoder is aligned where needed, and the motor is proved on our servo motor test system with a no-load run and a load test before it leaves our bench. Send the nameplate and we confirm repairability first. Star Automations is an independent multi-brand repair company and is not an OEM service centre.

Fuji Electric servo motor questions
Do you repair Fuji Electric servo motors?
Yes, including GYS and GYB series motors. Send the nameplate and we confirm repairability before you courier.
Do you need a Fuji Electric drive to test the motor?
No. Our servo motor test system runs Fuji Electric motors without the original drive, then a load rig applies load.
What should I send for a quote on a Fuji Electric motor?
A photo of the nameplate, the alarm code and a note on the symptom. We confirm repairability before you courier.
Is there a warranty?
A written warranty is given after a successful repair. Warranty terms are stated on each quotation.
