Product Description:

The 103H8223-5114 is a rotary actuator built by Sanyo Denki for the StepSyn Stepping Motors series. It fits directly into indexers, pick-and-place axes, or small conveyor drives where incremental position control is needed without a feedback device. By energizing its discrete stator phases in sequence, the motor advances by a fixed mechanical angle with each electrical command, allowing PLCs to translate pulse trains into repeatable linear or rotary motion in automated packaging, semiconductor handling, or laboratory equipment.

Its housing has an 86 mm frame, providing a square mounting face that aligns with NEMA 34 gearboxes and couplings. The motor has an angular increment of 1.8° per step, so 200 command pulses complete one mechanical revolution; this resolution simplifies motion profiles that rely on integer pulse counts. A peak static torque of 7.44 N·m holds loads when the coils are energized, supporting moderate-inertia tables without external brakes. The coil windings draw 4 A per phase at nominal drive settings, and the copper path has a resistance of 0.9 Ω per phase; these values support power supply sizing and thermal calculations. The unit is a stepping motor with a bipolar winding topology, so an H-bridge driver can reverse current in each coil and generate full-step, half-step, or microstep sequences as required.

The windings have an inductance of 8.1 mH per phase, which affects how quickly current rises as the command pulse rate increases. The electromagnetic structure uses two phases, allowing the motor to operate with the standard A-B excitation pattern common to many industrial stepper drives. Rotor dynamics are characterized by an inertia of 4.4 × 10^-4 kg·m², balancing acceleration responsiveness against the potential for overshoot during rapid changes in speed. The stainless-steel and laminated-core assembly weighs 3.5 kg, which should be considered for cantilever mounts or gantry axes where moving mass affects acceleration and cycle time.
