320 products
Capacitor-start NEMA frame general purpose AC motors are single-phase motors that use a capacitor to provide additional power during startup for higher torque than split-phase motors. They have a main winding and an auxiliary winding with a start capacitor for use in medium-to-high-torque requirements in auger drive, conveyor, shop tool, ventilation, and pump applications. Motors have NEMA frame construction with standard dimensions that allow drop-in replacement of motors from multiple suppliers with no modifications required to existing installations. Models usually have a single capacitor cover on the top or side of the motor shell that holds the start capacitor(s) and may also have a conduit box on one side that houses the electrical connections between the external power cables and the internal electrical wiring of the motor. The frame size for these motors is shown on the motor nameplate under “Frame” or “FR”.
NEMA 42 Frame Capacitor-Start General Purpose AC Motors
NEMA 42 frame capacitor-start general purpose AC motors have a standard 3/8" diameter, 1-1/8" length shaft whose center is 2-5/8" 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 42CZ. The letter “C” indicates that the motor can be face mounted and “Z” indicates that the frame has a nonstandard shaft. These frame standards and letter designations are defined by the National Electrical Manufacturers Association (NEMA).

NEMA 48 Frame Capacitor-Start General Purpose AC Motors
NEMA 48 frame capacitor-start general purpose AC motors have a standard 1/2" diameter, 1-1/2" length shaft whose center is 3" 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 48Z. The letter “Z” indicates that the frame has a nonstandard shaft. These frame standards and letter designations are defined by the National Electrical Manufacturers Association (NEMA).

NEMA 56 Frame Capacitor-Start General Purpose AC Motors
NEMA 56 frame capacitor-start 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 56Z or 56HC. The letter “Z” indicates that the frame has a nonstandard shaft, “H” indicates that the frame has a set of mounting holes at 3" and 5", 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).

NEMA 140 Frame Capacitor-Start General Purpose AC Motors
NEMA 140 frame capacitor-start general purpose AC motors have a standard 7/8" diameter, 2-1/4" 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 145TC. The letter “T” specifies integral HP motor dimension standards set by NEMA in 1953 and 1964, 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).
