Obsolete Servo Drives & Motors Sourcing

Discontinued servo platforms are our specialty: MINAS A5, Sigma-5, MR-J2/J3, Simodrive 611 — sourced globally, bench-tested, 12-month warranty.

Servo platforms get discontinued faster than PLCs: Panasonic retired the MINAS A5 line, Yaskawa is phasing out Sigma-5 in favor of Sigma-7, Mitsubishi's MR-J2/J3 amplifiers disappeared a decade ago, and Siemens Simodrive 611 has been end-of-life since the V60/SINAMICS transition. Machines built on these platforms keep running — and when a drive or motor fails, the only options are repair, retrofit, or the surplus market.

TGK Parts sources discontinued servo drives, motors, encoders and cables through a global surplus network, with bench testing where possible and a 12-month warranty on everything we ship.

Our sourcing process (quote within 12 hours)

  1. Send the full nameplate data: drive model, motor model, and any serial numbers — photos of both nameplates are ideal.
  2. We search the global surplus network for matched pairs (drive + motor) and compatible single units, and confirm compatibility with your machine's firmware.
  3. You receive a quote within 12 hours with condition stated clearly: new (sealed), tested surplus, or refurbished.
  4. Every unit is bench-tested where possible — powered, parameterized and run against a test motor — before shipping with a 12-month warranty.

Frequently asked questions

Can you source a matched drive and motor pair?

Yes — matched pairs are our most common request for obsolete platforms. Send both nameplate photos and we confirm compatibility before quoting.

How do you test a used servo drive?

Every drive is powered on a test bench, parameterized and run against a test motor with load; encoder feedback and I/O are verified before shipping.

The exact model is impossible to find — what are my options?

We offer three paths: (1) keep searching the surplus network longer, (2) supply a tested compatible alternative, (3) retrofit to a current platform with a drop-in drive + motor set. We quote all three so you can compare.
