Star Automations · Since 2000
Star Automations repairs and refurbishes servo motors from Siemens, Fanuc, Yaskawa, Mitsubishi, Allen-Bradley, ABB, B&R and other industrial brands. Each motor is opened, the failed parts are repaired, the encoder is realigned where needed, and the motor runs with no load and then under full load on our servo motor test system at the Chennai bench before dispatch. Servo drives, VFDs, PLCs, HMIs and boards are repaired too, since 2000.

The system is in-house. It runs servo motors from many brands on one rig, without each brand's own drive, and reads the motor's feedback device directly. Each motor gets a final run test and a load test, and goes back with a printed test report.
Brand names describe the equipment we repair. We are not a dealer or service partner of these manufacturers.

Star repairs multi-brand servo drives and servo motors at the component level. Servo motors we test include Allen-Bradley, Fanuc, Mitsubishi, Siemens, Yaskawa, Bosch Rexroth and Indramat, Panasonic and Sanyo Denki. The full list is on the motors page. If your model is not listed, send a photo of the nameplate on WhatsApp and we will confirm before you ship anything.
We test it on our in-house universal servo test system, which runs servo motors from many brands on one rig without each brand's own drive. It reads incremental, absolute and serial encoders, resolvers, Hall sensors and tachometers. Each refurbished motor gets a final run test on a universal servo drive and a load test on a custom-built rig, and goes back with a printed test report.
Repair-return means you send us the failed unit, and we repair, test and return the same unit to you. We log the serial number on arrival, trace the fault to the component, quote with findings, refurbish, test and dispatch with a test report. Warranty terms are stated on each quotation. Line-down jobs are prioritised.
Yes. Star works to your test methods, acceptance criteria and reporting. It is how we have worked for about ten years as all-India warranty and service partner for RealLand servo motors (China), and on all-India warranty and post-warranty servo repair support for Shibaura Machine (formerly Toshiba Machine). Most programmes start with a bench trial on 2–3 failed units.
Star Automations is headquartered in Puducherry, where our refurbishment factory of about 5,000 sq ft is. Our servo motor repair bench, with the universal servo test system, is in Chennai (about 3,000 sq ft, Poonamallee), and a facility of about 7,000 sq ft in Bengaluru that includes cable harness manufacturing. We also have sites in Hyderabad and Delhi. Servo motors can be couriered to the Chennai bench from anywhere in India.
Send a photo of the nameplate and a short description of the fault on WhatsApp to +91 97866 22233, or send an RFQ. For spares, send the part number and quantity. For OEM and EV programmes, we suggest a bench trial on 2–3 failed units.
