Us Motors D32S1AHC Three Phase Ac Motor 1.5 Hp 56C Odp

Product Description

The US MOTORS D32S1AHC is a three-phase, energy-efficient AC motor built for general-purpose industrial and commercial applications. Rated at 1.5 horsepower and 3450 RPM at 60 Hz, it operates in an open drip-proof (ODP) enclosure with a 56C frame. The steel frame and ball bearing construction support reliable continuous-duty operation. Full-load efficiency is rated at 86.00 percent with a 1.15 service factor, giving the motor headroom to handle brief overload conditions. Motor rotation is reversible, and the unit ships as a single-speed design. At 26 pounds, it is a manageable size for bench or field installation by a qualified electrician or mechanical technician.

This motor is suited for general-purpose applications in light industrial, commercial HVAC, and equipment-drive scenarios where a three-phase supply is available. The base and C-face mount configuration allows direct coupling to pumps, compressors, fans, or gear reducers. The 56C frame is a widely used standard frame size, making this motor a practical replacement or new-install option in a variety of equipment configurations. The ambient operating temperature rating is 40 degrees F, and the Class B insulation keeps winding temperatures within safe limits under normal load cycles.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-fit motor for three-phase general-purpose equipment using a 56C frame with base or C-face mounting. Referenced as equivalent to Dayton part number 1Z899.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and any applicable local codes. Disconnect and lock out all power before removing an existing motor or making any wiring connections. Verify supply voltage and phase configuration match the motor nameplate before energizing. Confirm shaft alignment and mount fastener torque per the driven equipment manufacturer's specifications before startup.
