Allen-Bradley servo motor repair
Star Automations repairs Allen-Bradley servo motors, including MP-Series, TL-Series and older Y and H series motors used with Kinetix and Ultra drives. 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 Allen-Bradley dealer or service partner; the brand name describes the motor we repair.
01Failures
Common Allen-Bradley servo motor failures
Feedback faults
Hiperface and resolver feedback alarms from encoder failure or cable damage.
Bearing and seal wear
Noise and contamination on motors in washdown and packaging lines.
Winding insulation
Ground faults from moisture in the winding.
Brake faults
Holding brakes that slip or do not release.
02Test bench
What the test bench checks
Allen-Bradley motors are tested on our servo motor test system without a Kinetix 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 MP-Series and older frames where the encoder, bearings, seal or brake failed and the frame is sound, and where a new motor would mean a long wait.
Replacement suits motors with mechanical damage or repeated winding failures. We give you the findings and photos so the decision is yours.

How to send the motor
You can send a servo motor from anywhere in India. Talk to us before you courier, so the unit is expected and logged on arrival.
Send the nameplate
WhatsApp a clear photo of the nameplate, the alarm code and what the machine was doing when it failed.
We confirm repairability
We tell you whether we can test and repair that model before anything is shipped.
Courier or pickup
Courier the motor to our Chennai bench, or ask us to arrange pickup where needed.
Inspection and quote
The motor is opened, inspected and photographed. You get the findings and a quote before work starts.
Repair, test, dispatch
Repaired, run-tested and load-tested, then dispatched with a printed test report.
Do you repair Allen-Bradley servo motors?
Yes, including MP-Series, TL-Series and older Y and H series motors used with Kinetix and Ultra drives. Send the nameplate and we confirm before you courier.
Do you repair motors from washdown lines?
Yes. Water ingress damage to encoders, bearings and seals is a common repair. We replace seals and note the cause on the report.
What should I send for a quote on a Allen-Bradley 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 Allen-Bradley drive to test the motor?
No. Our servo motor test system runs Allen-Bradley 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.
