Product Description:

The 103H89223-6341 is a hybrid stepper motor manufactured by Sanyo Denki within the StepSyn Stepping Motors series. In automated machinery, it receives sequential pulse commands from a drive and converts them into precise angular movements, allowing accurate open-loop positioning without a feedback device. This operating method supports repeatable motion in indexing conveyors, component feeders, and small gantry axes.

The rotor advances by 1.8° per step, so 200 full-step pulses complete one revolution and simplify motion programming. A holding torque of 19 N·m keeps loads stationary when command pulses stop, which is useful for vertical or load-bearing stages. Each phase requires a continuous current of 6 A to produce the rated torque, and the connected stepper drive must be sized to supply this current. Copper losses are affected by a phase resistance of 0.63 Ω, while a phase inductance of 8 mH influences current rise time as the pulse frequency increases. These electrical values determine the required drive voltage and the practical pulse rate before available torque begins to decrease. The bipolar winding arrangement supports high torque for the frame size, and the lead-wire connection permits plug selection or splice lengths that suit the machine wiring layout.

The square mounting flange measures 106 mm across and aligns with standard NEMA 42 mounting patterns. The housing has a length of 221.3 mm, so the machine layout must provide sufficient space for the motor body and shaft coupling. The motor weighs 10.5 kg, which adds mass to moving carriages, while its rotor inertia of 22 × 10⁻⁴ kg·m² must be considered when setting acceleration and deceleration rates. Its IP43 enclosure resists intrusion by objects larger than 1 mm and protects against water spray at limited angles, but the motor should not be exposed to direct washdown. A single output shaft with a key provides positive torque transmission to pulleys, couplings, or gearboxes.
