ProgrammeFor EV OEMs · After-warranty repair
EV motor and controller repair for EV OEMs, after warranty and out of warranty
Star Automations repairs EV hub motors, traction motors and motor controllers for electric two-wheeler and three-wheeler brands, motor and controller manufacturers, importers, and overseas companies selling into India. We take back units that are out of warranty or were never covered, repair them under your RMA numbers, test them, and return them with a report per serial. Your dealers get a serviceable unit at a lower cost than new, and you keep the customer, the warranty and the design.
01Who it is for
Built for the company behind the vehicle
This service is for the business that owns the product and the after-sales promise. Riders and fleet operators reach us through your dealer or service network.
EV brand owners
Electric two-wheeler, three-wheeler, e-rickshaw and light commercial vehicle brands whose dealers replace whole motors and controllers once the warranty ends.
Motor and controller makers
Make in India hub motor, mid-drive motor and controller manufacturers who supply vehicle brands and carry the field returns.
Importers
Companies importing hub motors and controllers for Indian vehicle brands, who need a repair route in India for units the overseas supplier will not take back.
Overseas powertrain companies
Motor and controller makers outside India who want failed units repaired and returned here, close to the vehicle.
02The after-sales gap
Why EV OEMs need a repair route
EV motors and controllers come back for a short list of reasons: water ingress after flooding or washing, a failed Hall or position sensor, a damaged phase lead or connector, worn bearings, or a burnt power stage in the controller.
Out of warranty, the dealer usually replaces the whole hub motor or controller. The rider pays more, the dealer waits for stock, and the failed unit is scrapped although most of it is sound.
Repair-return gives your service network a lower-cost option, keeps vehicles on the road, and sends failure data back to your engineering and supplier teams.
03Scope
What we repair
We work on the motor, its feedback and the controller that drives it. Tell us the model, voltage and power class, and we confirm what we can repair before you ship.
- BLDC hub motors for two-wheelers and three-wheelers
- Mid-drive and traction PMSM motors
- Motor controllers: power stage, gate drivers, control board
- Hall sensors, resolvers and position sensors
- Phase leads, connectors and motor harnesses
- Bearings, seals and water-ingress damage
- Magnet and rotor inspection
- Throttle, brake-cut and CAN interface faults on the controller
04How it works
How a repair programme starts
Start small. Send a few failed units, judge us on the reports, then agree the programme.
NDA and data
We sign your NDA and you share the motor and controller data you are willing to share: ratings, test limits and the faults you see most.
Bench trial
You send 2 to 3 failed units. We find the fault, repair them, test them and send a report on each.
Agree the method
We agree the test method, acceptance limits, report format and the RMA and serial numbering you use.
Run the programme
Units come in from your dealers or warehouse under your RMA numbers and go back repaired, tested and labelled, or marked not repairable with the reason.
Failure data
You receive a periodic summary of failure modes by model and batch, so your design and supplier teams can act on it.
05What you get
What comes back with every unit
| Field | What it records |
|---|---|
| RMA and serial | Your RMA number and the unit serial, traced from inward to dispatch |
| Fault as received | What was found on inspection, with photos |
| Root-cause class | Water ingress, sensor, bearing, winding, magnet, connector or controller power stage |
| Work done | Parts replaced, repairs made and resealing |
| Test results | Insulation, phase balance, Hall timing, back-EMF, and a run test with a controller |
| Result | Released for return, or not repairable with the reason |
Your warranty, your design, your firmware and the sale of new units stay with you. We do not deal with your customers unless you ask us to, and we do not offer them a replacement.
Warranty terms on our repair are stated on each quotation.
06Verification
How a repaired EV motor and controller are tested
Each motor is checked for insulation and phase balance, Hall sensor timing and back-EMF, then run with a controller. Seals are checked where water ingress caused the failure.
Controllers are function-tested with a motor, including throttle response and fault reporting. We do not change your firmware or calibration.
