B&R servo motor repair
Star Automations repairs B&R servo motors, including 8LS, 8LV and 8JS 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 full-load test before it leaves our Chennai bench. We are not a B&R dealer or service partner; the brand name describes the motor we repair.
01Failures
Common B&R servo motor failures
EnDat and encoder faults
Encoder communication alarms on motors with EnDat or Hiperface feedback.
Bearing wear
Noise on compact motors running fast cycles on packaging machines.
Brake faults
Brakes that drag or slip on vertical and indexing axes.
Connector and cable damage
Hybrid cable and connector damage from cable-chain flexing.
02Test bench
What the test bench checks
B&R motors are run on our servo motor test system without an ACOPOS drive, then loaded on the rig.
- 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 full-load run; speed and current against the nameplate
- Vibration and noise at rated speed
03Repair or replace
Repair or replace
Repair suits 8LS and 8JS motors with feedback, bearing, brake or connector faults, which is most of what we see on packaging machines.
Replacement suits motors with shaft or housing damage. If a machine builder supports the line, we can work to their test methods and reporting.

Repair, test, dispatch
Repaired, run-tested and load-tested, then dispatched with a printed test report.
Do you repair B&R servo motors?
Yes, including 8LS, 8LV and 8JS series motors. Send the nameplate and we confirm before you courier.
Do you repair B&R motors from packaging machines?
Yes. Packaging machines are where most B&R motors we repair come from.
What should I send for a quote on a B&R motor?
A photo of the nameplate, the alarm code and a note on the symptom. We confirm repairability before you courier.
Do you need a B&R drive to test the motor?
No. Our servo motor test system runs B&R motors without the original drive, then a load rig applies full load.
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.
