103H7523-6021 by Sanyo Denki

The Sanyo Denki 103H7523-6021 is a precision motor from the StepSyn Stepping Motors series designed for industrial automation applications. This 2-phase synchronous motor operates in direct relation to AC power frequency and delivers ultra-low speed rotation with high torque across its entire load range. With a withstand voltage of 1 kV AC for 1 minute, it ensures electrical robustness in demanding environments.

Built on a conversion principle derived from stepping motors for AC power use, the 103H7523-6021 features a reliable phase-shifter drive with C&R for single-phase AC and requires no external driver, simplifying system integration. It maintains constant speed operation across the full load range and achieves a winding temperature rise of 80 K under Sanyo Denki standard conditions. Mechanical precision is assured by minimal play: axial play 0.075 mm and radial play 0.025 mm at 4.4 N. The insulation system provides resistance 100 M6 between winding and frame (DC 500 V), promoting electrical safety.

Designed for industrial reliability, this motor tolerates ambient humidity from 2095% RH (no condensation) and withstands high thermal stress while maintaining torque consistency. Its robust construction minimizes wear, and its low leakage current (1 mA at withstand voltage) reduces maintenance downtime. The combination of precise mechanical tolerances, high insulation resistance, and phase-shifter drive technology makes the 103H7523-6021 a highly efficient and durable choice. In industrial automation systems, it delivers stable positioning, simplified installation, and long-term performance benefits.
