Us Motors D1C1J Psc Ac Motor 1 Hp 3450 Rpm 56 Frame Odp

Product Description

The US MOTORS D1C1J is a single-phase permanent split capacitor (PSC) AC motor built for general-purpose applications. Rated at 1 horsepower and 3450 RPM, it runs on 60 Hz power and delivers a full-load amperage draw of 13.4 amps at low voltage or 6.8 to 6.7 amps at higher voltage configurations. The motor features an open drip-proof (ODP) enclosure, Class B insulation, and a service factor of 1.25, giving it modest overload capability in clean, sheltered environments. Ball bearings support the shaft on both ends for reliable operation. The rigid mount configuration suits fixed-position installations where the motor frame is bolted directly to equipment structure. Licensed HVAC technicians, equipment service techs, and industrial maintenance professionals are the primary installers.

This motor is suited for general-purpose equipment installations in residential and light commercial settings where a single-phase PSC motor in a standard 56 frame is required. Typical applications include fans, blowers, compressors, pumps, and other belt- or direct-drive equipment that operates at or near 3450 RPM. The reversible rotation allows the motor to be configured for either direction of shaft spin at installation, adding flexibility across equipment types. The 5/8-inch shaft diameter and 1-7/8-inch shaft length are standard for the 56 frame and compatible with common couplings and pulleys in this class.

Installation Notes

Installation should be performed by a qualified electrician or licensed equipment technician in accordance with applicable NEC requirements. Disconnect and lock out all power to the equipment before removing the existing motor or making any wiring connections. Verify that supply voltage, phase, and frequency match the motor nameplate before energizing. Confirm shaft alignment and mounting bolt torque per the driven equipment manufacturer's guidelines before returning the system to service.
