Us Motors T32S3ACR 1-1/2 Hp Three Phase Ac Motor Tefc

Product Description

The US MOTORS T32S3ACR is a three-phase, energy-efficient AC motor built for general-purpose industrial and commercial applications. Rated at 1-1/2 horsepower and 1140 RPM nameplate speed, it operates on a 60 Hz supply and delivers a full-load efficiency of 80.00 percent with a service factor of 1.15. The motor features a totally enclosed fan-cooled (TEFC) enclosure housed in a steel frame, providing reliable protection against dust and moisture ingress. It is designed for installation by qualified electricians or mechanical contractors working on equipment drives, fans, pumps, and similar rotating machinery.

This motor is suited for general-purpose applications in light industrial, commercial, and mechanical-room environments. The 56C frame with C-Face mount makes it a direct-fit solution for close-coupled pump and blower assemblies where flange mounting is required. With reversible rotation, it accommodates flexible installation orientations. The 5/8-inch shaft diameter and 2-1/16-inch shaft length are standard dimensions for this frame class, simplifying coupling and drive selection.
