Us Motors D2P3B Three Phase Ac Motor Odp 2 Hp 184T

Product Description

The US MOTORS D2P3B is a three-phase, premium-efficient AC motor designed for continuous-duty industrial and commercial applications. Rated at 2 horsepower and 1175 RPM nameplate speed, it operates on a 60 Hz supply and is built on a 184T frame with a rigid mount configuration. The open drip-proof (ODP) enclosure allows airflow through the motor for effective cooling in clean, dry environments. Class F insulation and a 1.15 service factor provide thermal headroom for demanding duty cycles. Ball bearings support the 1-1/8-inch shaft for reliable, low-maintenance operation. Licensed HVAC and mechanical contractors, as well as industrial maintenance technicians, are the primary installers of this motor.

The D2P3B is suited for use in fans, blowers, pumps, compressors, and light conveyor applications where a three-phase power supply is available. Its 184T frame size and rigid mount base make it a direct fit in equipment designed to that NEMA frame standard. The ODP enclosure is appropriate for indoor installations or sheltered outdoor locations where the motor is protected from direct water exposure and excessive airborne contaminants. This motor is a common replacement or upgrade option in commercial HVAC air-handling units, industrial process fans, and pump systems operating at low speeds.

Key Features

• 2 HP three-phase premium-efficient motor with 87.50 percent full-load efficiency rating

• 184T NEMA frame with rigid mount base for straightforward equipment integration
• ODP enclosure provides ventilated cooling in clean, dry environments
• Class F insulation with 1.15 service factor for thermal reserve under load
• Ball bearing construction on a 1-1/8-inch diameter shaft for extended service life

Compatibility

Designed as an OEM-style replacement or upgrade for equipment built to the NEMA 184T frame standard requiring a 2 HP, 1175 RPM, three-phase rigid-mount motor. Cross-reference Dayton part number 5N305 for legacy replacement applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified mechanical technician in accordance with NEC requirements for three-phase motor circuits, including proper overcurrent protection and disconnect means. Disconnect and lockout all power to the equipment before removing the existing motor or making any wiring connections. Verify that the supply voltage and phase configuration match the motor nameplate before energizing. Ensure the mounting base and shaft alignment are within acceptable tolerances before final tightening to prevent bearing wear and vibration.
