Superior Electric SS451-1003 Synchronous Motor

The Superior Electric SS451-1003 Slo-Syn Synchronous Motor is a compact, 120 VAC single‑phase motor designed for precise, slow‑speed rotation. Manufactured by Superior Electric (a Danaher Motion brand), this Slo‑Syn unit delivers stable output at very low speeds for positioning and timing tasks in automation and instrumentation. At 50 Hz it runs at 20 RPM and at 60 Hz it runs at 24 RPM, making it well suited for rotary indexing tables, small automated feeders, and other applications requiring repeatable, step‑like motion control without conventional servo gear. The SS451‑1003 is a standalone motor in the Slo‑Syn family; for users needing higher output torque or different speed, a gearbox‑equipped variant exists (SS451TG3) with a 3:1 reduction ratio. This model is compatible with standard 120 V, 1‑phase drive schemes and is commonly used in lab equipment, packaging machinery, and compact automation systems where precise low‑speed actuation is essential.
