Us Motors U32E1DC Three Phase Ac Motor 1.5 Hp Tefc

Product Description

The US MOTORS U32E1DC is a three-phase, energy-efficient AC motor built for industrial and commercial applications where reliable continuous-duty performance is required. Rated at 1.5 horsepower and 3490 RPM at full load, this motor runs on 208 to 230 volts or 460 volts at 60 Hz, making it compatible with standard single-voltage and dual-voltage three-phase power supplies. The TEFC (totally enclosed, fan-cooled) enclosure protects internal windings from dust, moisture, and airborne contaminants. The steel frame is sized to the 143TC NEMA standard, and the rigid mount design secures the motor firmly to the driven equipment. Class F insulation supports sustained operation in elevated-temperature environments.

This motor is suited for HVAC equipment, pumps, compressors, fans, and general machinery drives in light industrial and commercial settings. The reversible rotation direction allows flexible installation regardless of driven-load orientation. A service factor of 1.25 permits short-term overload operation beyond the nameplate horsepower rating without damage to the motor windings. Licensed electricians and mechanical contractors typically handle installation where three-phase power is present. The 143TC frame is a widely used NEMA standard, making this motor a practical direct replacement in many existing mechanical configurations.

Key Features

• 1.5 HP output at 3490 nameplate RPM for high-speed driven-load applications
• Dual-voltage rated at 208 to 230 volts and 460 volts, 60 Hz three-phase
• TEFC enclosure keeps contaminants away from windings in dirty or wet environments
• 143TC NEMA frame with rigid mount for straightforward equipment alignment
• Class F insulation with 1.25 service factor for thermal headroom and short-term overload tolerance
• Reversible motor rotation to match driven-equipment requirements

Compatibility

Designed as an OEM-style replacement for 143TC frame, TEFC, rigid-mount three-phase AC motors rated at 1.5 HP. This motor is also referenced under Dayton part number 2R940.

Installation Notes

Installation should be performed by a licensed electrician familiar with three-phase motor wiring and applicable NEC requirements. Disconnect and lock out all power before removing the existing motor or making any wiring connections. Verify that the supply voltage matches the selected motor nameplate voltage tap before energizing. Confirm proper coupling alignment and belt tension where applicable before returning the driven equipment to service.
