Capacitor Start-Run NEMA Frame General Purpose AC Motors

Available190 products
Capacitor-start/run NEMA frame general purpose AC motors are single-phase and use a capacitor to provide additional power during startup for higher torque and a separate capacitor to run with higher operating efficiency compared to standard capacitor-start motors. They have a main winding and auxiliary winding with both a start capacitor and run capacitor for use in medium-to-high-torque requirements in air conditioner, auger drive, compressor, conveyor, fan, and pump applications. Motors have NEMA frame construction with standard dimensions for drop-in replacement of motors from multiple suppliers with no modifications required to existing installations. Models may have two capacitor covers on the top or side of the motor shell for the start and run capacitors and may also have a conduit box that houses the electrical connections between the external power cables and the motor's internal electrical wiring. The motor's frame size is shown on the motor nameplate under “Frame” or “FR”.
