Westinghouse 30 HP (575V) TEFC Electric Motor with Lovejoy SW150 Coupling Set

Item Overview

This listing is for a heavy-duty Westinghouse 30 HP (22 kW) 3-Phase Electric Motor. This is a high-efficiency, 575-volt motor designed for demanding industrial applications such as driving large pumps, compressors, or blowers.

The motor was professionally serviced, tested, and tagged by E&M Electric Northern (Edmonton, AB) in April 2018 (WO# 704867) and appears to have been kept as a ready-to-deploy spare since that time. It is strapped to a pallet and wrapped in plastic for protection.

Bonus Inclusion: This motor comes complete with a brand new, uninstalled Lovejoy SW150 Flexible Jaw Coupling Set. This includes two cast iron hubs and a complete SW150 Snap Wrap elastomer spider with retaining ring (P/N 68514424672, Made in USA). This coupling set alone is a significant value-add, allowing for immediate installation and alignment with driven equipment.

Application

A 30 HP, 3545 RPM (2-pole) motor running on 575V is a standard configuration in Canadian heavy industry, mining, and oil & gas. The high speed (3600 RPM synchronous) makes it ideal for direct-drive centrifugal pumps, high-speed fans, or compressors. The included Lovejoy SW150 coupling is perfectly sized to handle the torque output of a 30 HP motor at this speed.
