What the B-202-B-21 part number identifies
The Kollmorgen B-202-B-21 is a GoldLine B-Series brushless AC servo motor used in motion-control systems where the motor, feedback, cabling, and drive tuning must match the installed machine. Treat the complete part number as the purchasing target; small suffix differences can indicate a different winding, connector, brake, feedback, shaft, or mounting configuration.
Before replacing a B-202-B-21 servo motor
- Confirm the full nameplate part number: B-202-B-21.
- Verify that the machine uses a compatible Kollmorgen drive family, commonly ServoStar or BDS-era servo-drive hardware, and confirm the feedback interface before ordering.
- Match frame size, stack length, winding code, shaft, mounting face, brake option, connector orientation, and cable set.
- Back up drive parameters and record existing tuning before removal. A mechanically correct motor can still require drive setup before commissioning.
- Inspect coupling, load alignment, and cable condition. Motor failure symptoms can also come from cable, resolver, brake, or drive faults.
Condition options
Outdwella listings use clear condition labels. New means unused surplus stock when available. Used in Great Condition means the unit has been previously installed or operated and is represented as serviceable used hardware. Packaging, labels, and cosmetic condition can vary with surplus industrial parts.
Regional sourcing notes
For North America, Australia, Europe, and the Middle East, confirm import requirements, local electrical standards, machine safety requirements, and commissioning responsibility before purchase. Europe pricing and landed-cost planning should include VAT, duties, freight, and support handling where applicable.

FAQ
Is B-202-B-21 a servo drive?
No. The B-202-B-21 listing should be treated as a Kollmorgen GoldLine B-Series brushless AC servo motor. It works with compatible servo-drive hardware but is not itself the drive.
Can I replace it using only the base B-202 model?
No. Use the complete part number and suffix. The suffix can affect winding, feedback, shaft, connector, brake, or mounting details.
What should I check before powering up a replacement?
Confirm motor wiring, feedback wiring, grounding, brake wiring where present, drive parameters, current limits, encoder or resolver setup, and mechanical alignment before commissioning.
