SEW-Eurodrive servo motor repair

Star Automations repairs SEW-Eurodrive servo motors, including CMP and CMPZ servo 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.

06Questions

SEW-Eurodrive servo motor questions

Do you repair SEW-Eurodrive servo motors?

Yes, including CMP and CMPZ servo motors. Send the nameplate and we confirm repairability before you courier.

Do you need a SEW-Eurodrive drive to test the motor?

No. Our servo motor test system runs SEW-Eurodrive motors without the original drive, then a load rig applies load.

What should I send for a quote on a SEW-Eurodrive 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.

Encoders and feedback on these motors

SEW DFS and CFM motors use Stegmann Hiperface encoders or resolvers. See Hiperface encoder repair and resolver repair.
