Superior Electric SS50P3 Slo-Syn Synchronous Motor

Superior Electric SS50P3 Slo-Syn Synchronous Motor is a 120 V, 50/60 Hz, three-phase synchronous motor designed for very slow, high-torque motion. Identified as SS50-P3, this Slo-Syn variant delivers 0.67 RPM with a torque rating of 2000 oz-in, drawing about 0.3 A and weighing roughly 5 lb. The model is noted as discontinued by the manufacturer, which can affect parts availability and service options. Built for precise, low-speed rotation, the SS50P3 uses a three-phase drive to achieve its slow, controlled output and aligns with standard North American power systems at 120 V and 50/60 Hz. As a legacy Slo-Syn product, it reflects Superior Electric’s long-running focus on slow-speed, high-torque motion control for industrial equipment and precision instrumentation. Given the discontinued status, buyers should verify drive compatibility and current supplier availability before planning a retrofit or replacement.
