Capacitor Start-Run NEMA Frame General Purpose AC Motors
Available1 product
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”.

NEMA 56 Frame Capacitor-Start/Run General Purpose AC Motors
NEMA 56 frame capacitor-start/run general purpose AC motors have a standard 5/8" diameter, 1-7/8" length shaft whose center is 3-1/2" above the base mounting surface. Variations to the frame's standard dimensions and design are indicated by a letter designation following the frame number, such as 56HZ or 56C. The letter “H” indicates that the frame has a set of mounting holes at 3" and 5", “Z” indicates that the frame has a nonstandard shaft, and “C” indicates that the motor can be face mounted. These frame standards and letter designations are defined by the National Electrical Manufacturers Association (NEMA).
