Lenze servo motor repair
Star Automations repairs Lenze servo motors, including MCS 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.

06Questions
Lenze servo motor questions
Do you repair Lenze servo motors?
Yes, including MCS series motors. Send the nameplate and we confirm repairability before you courier.
Do you need a Lenze drive to test the motor?
No. Our servo motor test system runs Lenze motors without the original drive, then a load rig applies load.
What should I send for a quote on a Lenze 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.
Send the nameplate. We confirm repairability before you courier.
