Us Motors USMOTOR-U12P2DCR 1/2 Hp Tefc Flange Motor Nema 56C

Product Description

The US MOTORS USMOTOR-U12P2DCR is a three-phase, totally enclosed fan cooled (TEFC) general purpose AC motor rated at 1/2 horsepower and 1,770 RPM at 60 Hz. Built on a NEMA 56C frame with a machined C-face flange mounting surface, it bolts directly to driven equipment without a separate adapter. The motor operates on 208-230/460 volts AC at 60 Hz and is confirmed usable at 208 volts, making it flexible for a range of commercial power configurations. Insulation Class F construction and a 1.25 service factor give it headroom for moderate overload conditions. Licensed electricians and mechanical contractors are the primary installers.

This motor is suited for light industrial and commercial applications including air compressors and fan/blower assemblies. The TEFC enclosure keeps internal windings protected from dust and moisture without requiring external ventilation, which makes it appropriate for shop environments and mechanical rooms. It is rated for a maximum ambient temperature of 40 degrees C and runs at 1,455 RPM at 50 Hz, supporting dual-frequency installations where export or multi-standard equipment is a factor. The single-speed design keeps wiring and control requirements straightforward.

Key Features

• NEMA 56C C-face flange mount — machines directly to compressors, blowers, and pumps with no adapter plate
• TEFC enclosure protects windings in dusty or damp environments
• Confirmed usable at 208 volts AC in addition to 230/460 volt configurations
• Class F insulation with 1.25 service factor for sustained moderate overload tolerance
• Dual-frequency rated — 1/2 hp at both 60 Hz and 50 Hz
• NEMA Design Class B for standard torque and starting current characteristics
• CE, CSA Certified, and UL Listed

Compatibility

Designed as an OEM-style replacement or new-installation motor for equipment requiring a NEMA 56C C-face flange mount, three-phase power, and TEFC enclosure — commonly air compressors and fan/blower units in light commercial and industrial settings.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Disconnect and lock out all power to the circuit before mounting or wiring the motor. Verify supply voltage matches the motor nameplate before energizing — this unit supports multiple voltage configurations requiring correct lead connections at the terminal box. Ensure the driven equipment shaft and C-face bore are clean and free of burrs before bolting the motor in place.
