Warner Electric SS50-1280 Synchronous Motor

The Warner Electric SS50-1280 is a single-phase AC synchronous motor that delivers constant-speed rotation synchronized to the mains for precise motion control in industrial automation. Designed for 120 VAC, 60 Hz operation with a 0.3 A draw, it uses a brushless permanent-magnet construction in the SLO-SYN AC Series to maintain synchronous speed under changing load. Key physical specs include a 1/2 inch shaft diameter, face-mount configuration, natural convection cooling, and permanently lubricated bearings. Common applications span packaging machines, conveyors, indexing systems, label applicators, instrumentation, and inspection equipment where repeatable timing and synchronization are essential. Originating in the United States, this model is a discontinued OEM product available through surplus channels, with common replacements including Superior Electric SS50-P1, Warner Electric SS50E-P1, and Hansen Syn-chron AC Synchronous Motor Series.
