Superior Electric M111-FF-401 Synchronous Stepping Motor

Superior Electric M111-FF-401 is a Slo-Syn DC synchronous stepping motor designed for precise open‑loop positioning in automation and instrumentation. This 4‑conductor, round‑flange model (M111-FF-401) operates at 4.0 VDC with a per‑coil current rating of 3.4 A, and its windings present about 1.10 Ω of resistance and 18.0 mH of inductance. It delivers 200 full steps per revolution (1.8° per step) when driven by a suitable two‑phase driver, enabling repeatable, accurate positioning with simple control signals. The four‑wire bipolar wiring supports modern drivers and microstepping schemes, while the round flange provides compatibility with standard mounting patterns used in compact automation assemblies. Part of the long‑standing Slo‑Syn family, this motor is commonly used for indexing and precise feed movements in packaging equipment, laboratory instrumentation, CNC mini‑axes, and automated benches where compact size and reliable step accuracy matter.
