Industrial MC037100SJ Single Phase Induction Motor

MC037100SJ is a 5 HP, 120/240V, single-phase induction motor built as a replacement for Campbell Hausfeld air compressors and other light industrial equipment that use a 56-frame, 5/8-inch shaft. It delivers 3450 RPM, a typical speed for two-pole, 60 Hz operation, providing reliable startup and steady running in compressor circuits. The 56-frame housing and 5/8" shaft dimensions map to common replacement stock and mounting patterns, simplifying swap-in installations without need for custom adapters. This dual-voltage motor supports connection to either 120V or 240V mains, offering flexibility for shops with mixed tooling. While primarily used in air compressor replacements, its compact size and high-speed design also suit fans, blowers, and other small machines that fit the 56-frame, 5/8" shaft format and require a robust single-phase drive.
