Us Motors D34C2JC Psc Ac Motor 3/4 Hp 1725 Rpm 56C Odp

Product Description

The US MOTORS D34C2JC is a single-phase permanent split capacitor (PSC) AC motor built for general-purpose applications. Rated at 3/4 horsepower and 1725 RPM at 60 Hz, it runs in an open drip-proof (ODP) enclosure that allows airflow for cooling while protecting against light moisture and debris. The 56C frame with combined base and C-face mounting provides flexibility for direct-drive or belt-drive configurations. Ball bearings support reliable continuous duty, and the Class A insulation is rated for ambient temperatures up to 40 degrees F. A service factor of 1.25 gives the motor short-term overload headroom beyond its nameplate rating. Licensed electricians and HVAC technicians are the typical installers for this motor type.

This motor is suited for residential and light commercial general-purpose use. The reversible rotation makes it adaptable to a range of driven loads including fans, pumps, compressors, and other belt or direct-coupled equipment. The 56C frame is a standard NEMA frame size widely used in replacement and OEM applications across HVAC, refrigeration, and industrial machinery installations. Single-speed operation and a straightforward PSC run-capacitor circuit simplify wiring and troubleshooting in the field.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements. Disconnect and lock out all power to the unit before removing the existing motor or making any wiring connections. Confirm capacitor MFD rating matches the replacement motor requirements before energizing. Verify shaft diameter, rotation direction, and mounting configuration match the driven equipment before securing the motor in place.
