Superior Electric Co SS50P3 Synchronous Motor

The Superior Electric SS50P3 Synchronous Motor is a line-frequency, single-phase AC motor that delivers constant, low-speed rotation without external speed controls. It belongs to the SLO-SYN SS50 Series and combines an integrated gear reduction with a brushless permanent-magnet design to produce a precise 0.665 RPM output from a 120 VAC supply at 50/60 Hz. With a 0.3 A current rating and natural-convection cooling, this industrial-duty motor is built for continuous operation in automation contexts. It supports face-mount installation and uses permanently lubricated ball bearings within an enclosure suited for industrial environments. Typical applications include rotary indexing tables, conveyors, packaging equipment, timers, instrumentation, and other industrial motion-control systems that require repeatable, fixed-speed performance regardless of load variations. The SS50P3 is a direct line-frequency device—speed remains synchronized to the mains without relying on electronic drives. Common replacements listed alongside this model include SS50P2 and SS50-1280.
