Us Motors H2P2D 2 Hp Tefc Three Phase Ac Motor 145 Frame

Product Description

The US MOTORS H2P2D is a three-phase, premium-efficient AC motor built for demanding industrial and commercial applications. Rated at 2 horsepower and 1750 RPM at 60 Hz, it operates on 208 to 230 volts or 460 volts single-winding and accepts 190 to 380 volts for 50 Hz systems, giving it broad voltage compatibility. The totally enclosed fan-cooled (TEFC) enclosure protects internal windings from dust, moisture, and contaminants common in harsh service environments. Housed in a cast iron frame, this motor weighs 50 pounds and mounts in a horizontal-footed configuration on a standard 145 frame. It carries a Class F insulation rating and a 1.00 service factor. Licensed HVAC technicians, millwrights, and industrial electricians are the typical installers.

The H2P2D is suited for general equipment drives and harsh-environment applications including pumps, fans, compressors, conveyors, and similar rotating equipment in commercial and light industrial settings. Dual motor rotation allows flexible installation orientation. The 50 Hz voltage ratings make this motor usable in international applications or facilities with 50 Hz power distribution. The 145 frame designation follows NEMA standards, simplifying drop-in replacement in existing motor mounts designed to that frame size.

Key Features

• 2 HP three-phase premium-efficient design for reduced energy consumption under continuous load
• TEFC enclosure rated for harsh environments with dust, moisture, or airborne contaminants
• Dual rotation shaft allows clockwise or counterclockwise operation without repositioning the motor
• Cast iron frame construction for mechanical durability and heat dissipation
• Dual-frequency rated: 60 Hz at 1750 RPM and 50 Hz at 1430 RPM
• Class F insulation with double-shielded ball bearings for extended service life

Compatibility

Designed as an OEM-style replacement or new-installation motor for general equipment and harsh-environment applications requiring a NEMA 145 frame, three-phase, 2 HP TEFC motor with horizontal-footed mounting.

Installation Notes

Installation should be performed by a licensed electrician or qualified millwright in accordance with NEC requirements for motor branch-circuit protection and grounding. Disconnect and lock out all power sources before handling or wiring the motor. Verify supply voltage and frequency match the motor nameplate before energizing. Confirm shaft alignment and coupling condition before returning driven equipment to service.
