Siemens servo motor repair

Star Automations repairs Siemens servo motors, including 1FK7, 1FT7, 1FT6 and 1PH spindle motor families. 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 load run before it leaves our Chennai bench. We are not a Siemens dealer or service partner; the brand name describes the motor we repair.

Repair turnaround you can plan around

Send a photo of the nameplate first. We confirm whether the motor is repairable, and the quote, the same working day.

Emergency: same day

For a line-down motor, where the fault and parts allow. WhatsApp us before you send it so the bench is kept free.

Urgent: 3 working days

Repair, encoder alignment and test, counted from the day the motor reaches the bench and the quote is approved.

Standard: 7 working days

Full repair, encoder alignment, run test under load and a printed test report.

  • Free repairability check from a nameplate photo
  • Printed test report with every motor
  • Written warranty, terms stated on every quotation
  • Pickup can be arranged; parts that must be imported are quoted with their own timeline

01Failures

Common Siemens servo motor failures

Encoder and DRIVE-CLiQ faults

Encoder communication alarms on motors with DRIVE-CLiQ or older sin/cos and resolver feedback.

Bearing failure

Noise and heat on spindle and axis motors after long running hours.

Insulation breakdown

Ground-fault and overcurrent trips from moisture or contamination in the winding.

Brake wear

Holding brakes that no longer hold the rated torque.

02Test bench

What the test bench checks

Siemens motors are tested on our servo motor test system without a SINAMICS or SIMODRIVE drive, so the motor is checked on its own before it returns.

  • 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 load run; speed and current against the nameplate
  • Vibration and noise at rated speed
03Repair or replace

Repair or replace

Repair suits 1FK7, 1FT6 and 1FT7 motors where the fault is in the encoder, bearings, brake or insulation and the frame is sound.

Replacement suits motors with mechanical damage or a winding that cannot be saved. For older 1FT6 and SIMODRIVE systems, repair can keep a machine running while a migration is planned.

05How to send

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.

  1. Send the nameplate

    WhatsApp a clear photo of the nameplate, the alarm code and what the machine was doing when it failed.

  2. We confirm repairability

    We tell you whether we can test and repair that model before anything is shipped.

  3. Courier or pickup

    Courier the motor to our Chennai bench, or ask us to arrange pickup where needed.

  4. Inspection and quote

    The motor is opened, inspected and photographed. You get the findings and a quote before work starts.

  5. Repair, test, dispatch

    Repaired, run-tested and load-tested, then dispatched with a printed test report.

→How it works

From nameplate photo to a tested motor in 7 steps

One route for servo motors, encoders and drives. You see the price before any work starts, and the report before the unit leaves our bench.

06Questions

Siemens servo motor questions

More on the FAQ page.

Do you repair Siemens servo motors?

Yes, including 1FK7, 1FT7, 1FT6 and 1PH spindle motor families. Send the nameplate and we confirm before you courier.

Do you repair 1FT6 motors that are no longer made?

Yes, where the frame is sound. Older motors are a common reason plants choose repair over replacement.

What should I send for a quote on a Siemens 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 Siemens drive to test the motor?

No. Our servo motor test system runs Siemens motors without the original drive, then a load rig applies load.

Is there a warranty?

A written warranty is given after a successful repair. Warranty terms are stated on each quotation.

Encoders and feedback on these motors

Siemens 1FT6 and 1FK6 motors use Heidenhain ERN 1387 or EnDat EQN 1325 encoders; 1FT5 motors use ROD encoders or Hall and tach feedback. See Heidenhain encoder repair.

05Why Star

One universal test bench for Siemens and 180+ other servo brands

Most repairers test a servo motor on the drive of its own brand, or not at all. Star Automations tests every Siemens servo motor on its Universal Servo Motor Repair Equipment (Mitchell TI-5000JX), India’s first universal servo motor test system. It reads and aligns the feedback device and runs the motor under load without the original drive, so the result is the same whatever the brand.

  • Encoder and feedback read, zero position set and alignment checked before dispatch
  • No-load and load run, with speed and current compared against the nameplate
  • One test report format for every brand, so mixed fleets are easy to compare
  • Motors from machines that mix Siemens with other makes can go in a single consignment
