Us Motors D1P3B Three Phase Ac Motor Odp 1 Hp 145T

Product Description

The US MOTORS D1P3B is a three-phase, premium-efficient AC motor with an open drip-proof (ODP) enclosure, designed for industrial and commercial drive applications. Rated at 1 horsepower and 1165 RPM at 60 Hz, it runs on a 145T steel frame with a rigid mount configuration. Ball bearings support the shaft, and Class F insulation protects the windings against heat buildup during continuous operation. Full-load efficiency is rated at 82.50 percent with a service factor of 1.15, giving it modest overload capacity. Licensed electricians and millwrights typically handle installation in motor-driven equipment such as pumps, fans, compressors, and conveyors.

The D1P3B is suited for three-phase power applications in light industrial, commercial HVAC, and process equipment settings. Its 1165 RPM nameplate speed makes it appropriate for lower-speed drive loads where reduced output shaft speed is needed without an external speed reducer. The rigid mount base allows direct bolt-down to equipment frames or motor mounts. With a single operating speed and no built-in thermal protection, this motor is intended for use in systems that provide their own overload and thermal protection devices per applicable electrical codes.

Key Features

• 1 HP three-phase premium-efficient motor rated at 1165 nameplate RPM
• ODP enclosure suitable for indoor and sheltered outdoor installations with adequate airflow
• 145T steel frame with rigid mount for direct equipment mounting
• Ball bearing construction for reliable radial and axial load handling
• Class F insulation rated for elevated winding temperatures
• 1.15 service factor allows short-duration overload operation above nameplate rating

Compatibility

Designed as an OEM-style replacement or new-installation three-phase AC motor for equipment requiring a 145T frame, rigid mount, 1 HP, 1165 RPM motor with an ODP enclosure. Cross-references Dayton part number 5N301.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Disconnect and lock out all power sources before mounting or wiring the motor. Verify that the supply voltage, phase configuration, and amperage capacity of the circuit match the motor nameplate data before energizing. Because this motor has no built-in thermal protection, an appropriately sized external overload relay or motor protection device must be installed in the circuit.
