Us Motors WDS12S2AHC 1/2 Hp Tefc Three Phase Ac Motor

Product Description

The US MOTORS WDS12S2AHC is a three-phase, energy-efficient AC motor built for industrial and commercial applications requiring reliable continuous-duty operation. Rated at 1/2 horsepower and 1755 nameplate RPM, it operates on 208 to 230 volts or 460 volts at 60 Hz, making it compatible with both standard and high-voltage three-phase services. The TEFC (totally enclosed, fan-cooled) enclosure protects internal windings from dust, moisture, and debris. With a Class F insulation rating and a 1.15 service factor, the motor handles moderate overload conditions without damage. Full load efficiency is rated at 78.50 percent. The motor features a reversible rotation, offering flexibility for varied drive configurations. It is sized on a 56HC frame and weighs 34 pounds.

This motor suits light-duty industrial equipment, HVAC auxiliary drives, pumps, fans, compressors, and conveyor applications in commercial or light industrial settings. The rigid mount configuration allows direct bolting to equipment bases or fabricated mounting plates. Its dual-voltage capability — 208 to 230 volts or 460 volts — lets technicians match the motor to the available facility power without sourcing an alternate unit. Licensed electricians and millwrights handle installation, typically in facilities with existing three-phase power distribution.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC requirements for motor branch circuits, including proper overcurrent protection and disconnect means. Shut off and lock out all power to the circuit before making any wiring connections. Verify supply voltage matches the motor nameplate before energizing. Confirm mounting hardware torque and shaft alignment with the driven load before startup to prevent premature bearing wear.
