Motors that keep systems moving air

Motor failures are one of the most common causes of airflow loss—no heat, no cool, icing, and poor comfort. U.S. Motors® offers AC, DC, and EC motor options used in HVAC equipment where reliability and proper performance matter.

For a successful replacement, matching the key specs is critical: voltage, horsepower, RPM, frame size, rotation, shaft dimensions, and mounting style. For EC/ECM-style motors, control type and compatibility also matter.

If you’re unsure about the right replacement, send a photo of the motor label/nameplate and the equipment model number—we’ll help match it.

Fast motor match checklist
Send: motor model/part #, voltage, HP, RPM, frame, and a nameplate photo if possible—plus the equipment model number.

U.S. Motors — FAQs

What’s the most important info to match a motor?

Voltage, HP, RPM, frame size, rotation, and shaft dimensions. A nameplate photo is the fastest way to verify all specs.

Are EC/ECM motors universal replacements?

Not always—controls and programming/compatibility matter. Matching the exact motor type and control method helps ensure proper operation.

Can you help me confirm wiring and rotation?

Yes—share the motor model, application, and a nameplate photo and we’ll help verify the best match and key install details.
