Industrial MC006100AJ Air Compressor Motor 240V Single Phase

The MC006100AJ is a direct-replacement electric motor for stationary air compressors, offered in a 56-frame Emerson/A.O. Smith design for 240V, single‑phase operation and designed to fit in standard 56-frame compressor mounts. Some retailers label this family as 5 HP, while catalog references for the same model indicate 5.5 HP, so you may see either rating in listings depending on stock. Built to drop into compressors that originally used the MC006100AJ/AV family, this motor targets reliability and compatibility in industrial air‑compression systems, enabling continued operation of equipment that relies on 240V single‑phase power with a 56-frame motor footprint.
