Us Motors WD32S1AC 1.5 Hp Three Phase Tenv Ac Motor 56 Frame

Product Description

The US MOTORS WD32S1AC is a three-phase, energy-efficient AC motor built for continuous-duty industrial and commercial applications. It features a TENV (totally enclosed non-ventilated) enclosure in a 56 frame with a combination base and C-face mount configuration. Rated at 1.5 horsepower and 3450 RPM at 60 Hz, the motor delivers a full-load efficiency of 89.19 percent and carries a 1.15 service factor, offering a modest overload buffer for variable load conditions. Ball bearings support the shaft, and Class F insulation ensures durability under elevated operating temperatures. Installation is handled by licensed electricians or qualified industrial maintenance technicians.

The WD32S1AC is suited for washdown environments, making it appropriate for food processing, agricultural, and light industrial facilities where moisture exposure is a regular concern. The TENV enclosure prevents water ingress without relying on external ventilation, keeping contaminants out of the motor windings. The 56 frame footprint and dual base and C-face mount style allow it to be bolted directly to equipment housings or mounted on a standard base, giving installers flexibility in tight machinery bays. Single-speed operation simplifies wiring and control integration.

Key Features

• 1.5 HP three-phase output at 3450 RPM for high-speed drive applications
• TENV enclosure rated for washdown duty environments
• 89.19 percent full-load efficiency meets energy-efficient motor standards
• 1.15 service factor provides continuous overload headroom
• Reversible rotation simplifies installation orientation
• Class F insulation handles sustained elevated winding temperatures
• Ball bearing construction for reliable radial and axial load handling

Compatibility

The WD32S1AC is noted as a replacement for Dayton part number 5M267. It is designed for three-phase power systems operating at 60 Hz and fits standard 56-frame motor mounting configurations with base or C-face attachment points.

Installation Notes

This motor should be installed by a licensed electrician in accordance with NEC requirements for three-phase motor circuits, including proper overcurrent protection and grounding. Disconnect and lock out all power to the driven equipment before removing the existing motor or making any wiring connections. Verify that the supply voltage, phase configuration, and amperage capacity match the motor nameplate before energizing. Do not run the motor without confirming the driven load is within the rated horsepower and service factor range.
