Superior Electric SS221CT Stepping Motor

The Superior Electric SS221CT is a SLO-SYN AC synchronous stepping motor designed for precise, low-speed positioning when driven from 120 VAC, 60 Hz. It delivers about 200 oz-in of torque at 72 rpm and uses a 1.8° step angle (200 steps per revolution); shafts are standard with flats or a keyway. When operated from a single-phase supply, a phase-shifting network is required to provide the two- or three-phase excitation used by SLO-SYN motors. This model is part of the SLO-SYN family of motors, known for compact hybrid stepping action and straightforward integration into automation or control systems requiring repeatable incremental motion.
