Frequently asked questions
Do you repair Gefran servo motors?
Yes. We repair Gefran servo motors, including resolver replacement and alignment. Send the nameplate photo and the fault and we confirm repairability first.
Why does a new resolver need alignment?
The resolver tells the drive the rotor position. It must be aligned to the motor, or the motor will not run correctly. We align it and test the motor before return.
Can you show a repaired motor running?
Yes. The video on this page is the final run after a resolver replacement.
Do you also repair the Gefran drive?
Send the drive details and the fault and we tell you what is possible.
Are you an authorised Gefran service centre?
No. Star Automations is an independent multi-brand repair company, not an OEM or authorised centre.
How do I send the motor?
Courier or transport to our bench in Chennai, Puducherry or Bengaluru. Send the nameplate photo first so we confirm repairability.
Do you provide a test report?
We test the repaired motor on our universal servo test system and send the result with it.
