Replacement for obsolete servo motors: adapter, motor and drive setup

When an obsolete servo motor cannot be repaired or sourced, Star Automations can propose a compatible replacement: a matched motor, a flange or shaft adapter where needed, and drive parameters set up for the axis. Our custom brushless and PMDC servo motors cover small and medium axes (brushless motors up to 1 kW). Send the nameplate photos of the motor and the drive, and we tell you whether a replacement is feasible.

What we repair

When an obsolete servo motor cannot be repaired or sourced, Star Automations can propose a compatible replacement: a matched motor, a flange or shaft adapter where needed, and drive parameters set up for the axis.

Work is arranged from our Chennai, Puducherry and Bengaluru sites. We confirm what is possible from your photos before anything ships.

  • Motor, adapter and drive matched to the axis
  • Custom brushless and PMDC servo motors
  • Parameter and encoder set-up for the replacement
  • Repair is checked first; replacement only if needed

03Faults

Common situations

Same kW but the drive rejects the motor

The drive checks series, encoder type and motor ID. A replacement must match these or be re-parameterised.

Flange and shaft do not fit

An adapter plate and coupling can solve mounting, but shaft height and load need checking.

No spare available anywhere

If the motor cannot be sourced or repaired, a compatible replacement may keep the machine running.

Whole machine due for upgrade

A compatible motor and drive can be a first step before a full control upgrade.

07FAQ

Frequently asked questions

Can you replace an obsolete servo with a different make?

Often, for small and medium axes. We check the motor, the encoder, the drive and the mechanics and tell you whether it is feasible.

Will it work with my existing drive?

Possibly, with parameter and encoder set-up. If the drive is also obsolete, we can propose a matched motor and drive.

What is the power range you can supply?

Our custom brushless motors go up to 1 kW, and we also make DC and PMDC servo motors. For larger motors, tell us the rating and we advise.

Do you try to repair the original first?

Yes. Repair is checked first. A replacement is proposed only if the original cannot be repaired or sourced.

Will the machine behave the same?

The aim is equivalent torque, speed and feedback. Tuning on the machine is part of the set-up.

What should I send?

Nameplate photos of the motor and drive, the machine type and any drawings. Use the checklist on this page.

Is this a standard product?

No. Each replacement is checked for the axis and quoted separately.
