Us Motors WDS1S2AHC 1 Hp Three Phase Ac Motor Tefc 56HC

Product Description

The US MOTORS WDS1S2AHC is a three-phase, energy-efficient AC motor built for industrial and commercial applications requiring reliable continuous-duty operation. Rated at 1 horsepower and 1750 RPM nameplate speed, it operates on 208 to 230 volts or 460 volts at 60 Hz, making it suitable for dual-voltage installations. The motor features a totally enclosed fan-cooled (TEFC) enclosure and a Class F insulation rating, providing strong protection against dust, moisture, and heat in demanding environments. Full load efficiency is rated at 85.50 percent with a 1.15 service factor. Licensed electricians and industrial maintenance technicians are the primary installers for this type of motor.

This motor is suited for light industrial machinery, pump drives, fan assemblies, and general-purpose mechanical loads in commercial and industrial settings. The rigid mount configuration and 56HC frame size make it a direct fit for standard motor mounting bases and equipment designed around NEMA 56HC frame dimensions. The reversible rotation feature adds installation flexibility when the driven load requires a specific shaft direction. Full load amperage draws 3.1 to 2.9 amps at 208 to 230 volts and 1.4 amps at 460 volts.

Compatibility

Designed as an OEM-style replacement or new-installation motor for equipment built around NEMA 56HC frame rigid-mount three-phase motor specifications. Also referenced under Dayton part number 6ML25.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. Disconnect and lock out all power to the circuit before mounting or wiring the motor. Verify supply voltage and phase configuration match the motor nameplate before energizing. Confirm the driven load coupling and shaft alignment are correct before initial startup to avoid premature bearing wear.
