Nidec Electric Motors for Farm, HVAC, and General Use

US Motors, now part of Nidec Motor Corporation, has a long track record in both farm equipment and residential or light commercial HVAC systems, and our catalog covers both sides of that range. You'll find farm duty motors up to 10HP alongside furnace, air handler, and HVAC replacement motors, plus application specific options like oil burner, air compressor, and circulating pump motors, so you can search by the job the motor needs to do instead of comparing specs from scratch.

Farm Duty Motors Built to Handle Field Conditions

For agricultural equipment, our Nidec farm duty lineup runs from 1.5HP up to 10HP, in enclosures suited to dusty or exposed outdoor conditions. These motors are a common replacement on grain handling equipment, augers, and other farm machinery where a standard general purpose motor would wear out faster than intended.

HVAC and Furnace Replacement Motors

If you're replacing a motor in a furnace, air handler, or similar HVAC equipment, our Nidec catalog includes several purpose built replacement motors sized for that exact job. These smaller motors are designed as close matches for the originals installed by equipment manufacturers, so getting the horsepower and speed right matters more than it would on a larger industrial motor.

Single Phase Motors in Common Voltages

Every Nidec motor in our catalog runs on single phase power, with common voltages like 115V, 208V, and 230V represented across the lineup. Whether you're working on farm equipment or HVAC systems, this covers the vast majority of the residential, agricultural, and light commercial applications these motors are built for.

Need Help Finding the Right Replacement?

If you're not sure which Nidec or US Motors model replaces what's currently installed, our team can help you cross-reference an old model number or nameplate to find the correct match. We also offer electric motor repair services if your existing motor is worth saving instead of replacing outright.
