Us Motors WD1S2AC Three Phase Ac Motor 1HP Tefc 56C

Product Description

The US MOTORS WD1S2AC is a three-phase, energy-efficient AC motor built for industrial and commercial applications requiring reliable continuous-duty performance. Rated at 1 horsepower and 1725 RPM nameplate speed, it runs on 230/460 volts at 60 Hz with a full load amperage of 3.6/1.8 amps. The totally enclosed, fan-cooled (TEFC) enclosure protects internal components from moisture and contaminants, making it well suited for washdown environments. Class F insulation and a 1.15 service factor provide additional thermal headroom during demanding operating cycles. Licensed electricians and motor technicians are the typical installers for this type of unit.

This motor is rated for washdown applications and carries a reversible rotation design, allowing flexibility in installation orientation. The 56C frame with base and C-Face mount options supports direct coupling to pumps, fans, compressors, and other driven equipment. It operates at an ambient temperature rating of 40 degrees F and delivers a full load efficiency rating of 78.50 percent. The steel frame construction adds durability in wet or corrosive service environments where a standard open motor would be unsuitable.

Key Features

• 1 HP, 1725 RPM nameplate speed on a 56C steel frame
• TEFC enclosure rated for washdown and moisture-exposed environments
• Dual-voltage operation at 230/460 volts, 60 Hz, single speed
• Reversible motor rotation for flexible installation configurations
• Class F insulation with 1.15 service factor for thermal margin
• Base and C-Face mount style supports direct-coupled driven loads
• Ball bearing design for long service life under radial and axial loads

Compatibility

Designed as an OEM-style replacement or upgrade motor for three-phase driven equipment requiring a 56C frame, TEFC enclosure, 1 HP rating, and base or C-Face mount configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for motor branch circuits, including proper overload protection and disconnect means. Disconnect and lock out all power before servicing or mounting the motor. Verify that supply voltage and phase configuration match the motor nameplate before energizing. Shaft alignment to the driven load should be confirmed before startup to prevent premature bearing wear.
