Variable Frequency Drives

Variable Frequency Drives — New & Used

Variable Frequency Drives (VFDs) regulate motor speed and torque by adjusting frequency and voltage, improving energy efficiency, extending equipment life, and enhancing process control. They’re essential in pumps, fans, conveyors, and machinery requiring variable-speed operation.

At Surplus Select, we offer a rotating selection of new and used OEM VFDs across horsepower ranges, voltages, and control formats. Our surplus pricing helps OEMs, integrators, and MRO teams upgrade or replace drives without paying full catalog cost.

Price Match — We match any authorized distributor on identical in-stock parts, so you can source parts at surplus pricing with distributor-level assurance.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the parts you actually need.

Fast U.S. Shipping — Most orders ship same or next business day from our U.S. warehouse to keep your line running.

Find Your VFD Fast (Search-First)

Search your model or part number (e.g., ACS580-01-045A-4, 30 HP VFD 480V, low-harmonic VFD).
No model? Try specs like “25 HP VFD 230V”, “servo drive 400V”, “pump VFD 10 HP”.
Need special features? Add PLC interface, harmonic filtering, UL listed, or NEMA enclosure.
