Motors · Refurbishment and repair-return
Star Automations refurbishes servo motors, BLDC and permanent-magnet motors, EV motors and special high-value motors at its Chennai bench and Puducherry factory, India. Each motor is refurbished as required (windings, bearings, encoder, brake, sealing), run-tested on a universal servo drive, load-tested on a custom-built rig and returned with a printed test report.
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. So a motor is proven to run, under load, before it goes back to you.
Brand names describe the equipment we test. If your motor or encoder is not listed, send the nameplate and we will check before you ship.
Permanent-magnet motors with feedback and electronics are our core work. Each type has its own failure pattern and its own test.
AC servo motors from the brands above, on machine tools, packaging lines, robots and presses.
Brushless DC, EC and permanent-magnet synchronous motors, including motors with integrated drive electronics.
Traction and auxiliary motors for electric two- and three-wheelers, with their controllers. For four-wheelers, we repair low-voltage boards.
Motors that are costly to replace, have long lead times or are no longer made. Each one is reviewed before we quote.
Work is decided by what the inward tests find, and quoted with those findings before we start.
How repair-return works, step by step Rotor and impeller dynamic balancing Motor electrical testing: insulation, hipot, windingFor servo motor brands and series the test system covers, we can often ship a tested exchange unit while your motor is refurbished. Ask for availability with the part number.
Line-down jobs are prioritised. Warranty terms are stated on each quotation.
When the motor is sound and the feedback device has failed, a whole exchange motor is more than you need. Where the failed unit is in this month’s pool at our Chennai bench, we can swap a tested encoder against it the same day. The pool covers Sick, Fanuc serial, Tamagawa and Heidenhain EnDat.
The replacement is tested on our bench before it goes out. The encoder is aligned to the rotor, the offset file is saved against that motor, and the printed test report travels with it.
Other brands are repair-and-return with an alignment report, not a same-day swap. Send the part number from the encoder label on WhatsApp +91 97866 22233 and we confirm what is in the pool.
Where the motor itself needs refurbishment, the exchange unit above is the route.
A refurbished motor keeps its copper, steel, magnets and housing in service. For plants and OEMs, that means fewer scrapped motors and older machines that stay productive.
Star manufactures small brushless motors up to 1 kW, for India and for export.
Star works to your test methods, acceptance criteria and reporting. The universal servo test system lets us verify each motor against your acceptance criteria and report per unit, by serial number.
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.
When a servo motor or drive family is no longer supported, refurbishment keeps you running while you plan the next step. When it is time to change, we select a current servo package for the machine, migrate the drive and PLC, then install and commission it.
You get one team that knows the old system from repairing it and the new one from commissioning it.
Retrofit and migrationWe 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.
The system tests servo motors from Allen-Bradley, Fanuc, Mitsubishi, Siemens, Yaskawa, Bosch Rexroth and Indramat, Panasonic, Sanyo Denki, Kollmorgen, Omron, Beckhoff, B&R, Baumüller, SEW-Eurodrive and others listed on this page. If your motor is not listed, send the nameplate and we will check before you ship.
Yes. Motors are refurbished as required: windings, bearings, encoder, brake and sealing. What is needed is decided by the inward insulation, winding and feedback tests, and quoted with those findings before work starts. Every motor is then run-tested and load-tested before return.
Yes. We refurbish BLDC and permanent-magnet motors, including motors with integrated electronics, and traction and auxiliary motors for electric two- and three-wheelers. They are checked for phase balance, insulation resistance, hi-pot, back-EMF and Hall or encoder signals, then run-tested. For EV OEMs, Star works to your test methods, acceptance criteria and reporting.
For servo motor brands and series our test system covers, we can often ship a tested exchange unit while your motor is refurbished. Ask for availability with the part number on WhatsApp at +91 97866 22233. Line-down jobs are prioritised.
The printed test report records the motor's identity and serial number, its inward condition, what we found and replaced, electrical and feedback test results, and run and load test results against the acceptance criteria, with a pass or fail and a sign-off. A sample is on our sample test report page.
For Sick, Fanuc serial, Tamagawa and Heidenhain EnDat, when that part is in the pool. Send the part number on WhatsApp +91 97866 22233. Other brands are repair-and-return with an alignment report, not a same-day swap.
A paid check of up to ten axes: waveform, multiturn battery, cable and connector. You get a list of what is drifting. It is not a free service visit.
Yes, as its own job. We do not treat a glass scale as part of a motor rewind.
Only if your drive already reads the encoder protocol. If it does not, we will say no. Send the drive nameplate with the motor.
A photo is enough. We reply with what we can test, what we expect to find and what happens next. WhatsApp or call +91 97866 22233, or email info@starautomations.com.
