Us Motors D32P3B Three Phase Ac Motor 1.5 Hp 1180 Rpm

Product Description

The US MOTORS D32P3B is a premium efficient, three-phase AC motor built for continuous-duty industrial and commercial applications. Rated at 1.5 horsepower and 1180 RPM nameplate speed, it operates on a 60 Hz supply and is housed in an open drip-proof (ODP) enclosure mounted on a rigid 182T frame. The Class F insulation and 1.15 service factor allow the motor to handle occasional overload conditions without sacrificing winding life. Ball bearings support the shaft at both ends, and the 1-1/8 inch diameter shaft extends 2-3/4 inches for direct coupling or pulley-driven loads. Licensed electricians and millwrights are the typical trades installing this unit in pumping, fan, conveyor, and light industrial drive systems.

This motor is suited for three-phase power installations in commercial and light industrial settings where premium efficiency and low-speed torque are required. Typical applications include HVAC equipment drives, pump systems, air handling units, and industrial process machinery. The rigid mount base simplifies installation on standard motor mounts and equipment pads. With a full-load efficiency rating of 86.50 percent, the D32P3B meets premium efficiency standards appropriate for facilities seeking reduced operating costs on continuously running equipment.

Key Features

• 1.5 HP three-phase premium efficient motor rated at 1180 RPM for low-speed, high-torque applications
• ODP enclosure provides ventilation for heat dissipation in clean, dry indoor environments
• Class F insulation with 1.15 service factor supports intermittent overload without accelerated degradation
• Ball bearing construction at both ends for smooth, low-maintenance shaft support
• Rigid 182T frame mount ensures secure, stable installation on standard equipment bases
• 86.50 percent full-load efficiency rating reduces energy consumption on continuous-duty cycles

Compatibility

Designed as an OEM-style replacement or upgrade motor for three-phase, 60 Hz commercial and industrial applications requiring a 182T rigid-mount frame, 1.5 HP output, and 1180 RPM nameplate speed. Cross-references Dayton part number 5N303.

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 that the supply voltage and phase configuration match the motor nameplate before energizing. The ODP enclosure is not rated for wet or outdoor exposure; install only in clean, dry locations with adequate airflow around the motor housing.
