Bosch Rexroth servo motor repair
Star Automations repairs Bosch Rexroth servo motors, including IndraDyn S motors such as MSK and MS2N, and the older MKD and MKE. 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.

02Failures
Common Bosch Rexroth servo motor failures
Encoder and feedback faults
Feedback faults on resolver or encoder, and bearing wear on long-running axes.
Bearing noise
High-cycle axes wear bearings early; noise and heat show first.
Brake faults
Brakes that drag on release or slip when holding a load.
Cable and connector damage
Flexing in cable chains breaks feedback and power leads at the motor connector.
03Test bench
What the test bench checks
- Insulation resistance and hi-pot
- Winding resistance and balance
- Encoder or resolver feedback and commutation offset
- Brake release and holding, where fitted
- No-load run, then load run; speed and current against the nameplate
- Vibration and noise at rated speed

06Questions
Bosch Rexroth servo motor questions
Do you repair Bosch Rexroth servo motors?
Yes, including IndraDyn S motors such as MSK and MS2N, and the older MKD and MKE. Send the nameplate and we confirm repairability before you courier.
Do you need a Bosch Rexroth drive to test the motor?
No. Our servo motor test system runs Bosch Rexroth motors without the original drive, then a load rig applies load.
What should I send for a quote on a Bosch Rexroth 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
MSK motors use EnDat or Hiperface encoders, MSM motors use Tamagawa MFE0017, and Indramat MDD, MHD, MKD and MKE motors use Indramat digital encoders or resolvers with memory boards. See Heidenhain, Stegmann, memory programming and resolvers.
