103-8572-7041 by Sanyo Denki

The Sanyo Denki 103-8572-7041 stepping motor is a high-precision drive solution in the StepSyn Stepping Motors series, engineered for demanding industrial automation environments. Manufactured by Sanyo Denki, the 103-8572-7041 model delivers fine resolution with a step angle of 0.72° across a robust five-phase system. Its compact form factor and moderate weight of 2.32kg allow straightforward integration into motion control sequences without imposing excessive load on machine structures. Designed for reliable operation at altitudes up to 1000 m, the motor suits a wide range of factory and process automation tasks.

The motor’s physical and electrical parameters are optimized for repeatable performance. It features a current rating of 0.75A per phase and a five-wire configuration to simplify connection topology. The number of phases: 5 supports smooth torque output and reduced vibration during stepping sequences. With a shaft diameter of 9.5mm and a flange diameter of 60mm, the unit mounts easily to standard fixtures and couplings. The length (without flange & shaft) of 94mm combined with a square body measuring width: 86mm and height: 86mm ensures compatibility with tight installation envelopes.

Operational performance emphasizes precise incremental motion and dependable control. The 0.72° step angle yields high positional accuracy for indexing and micro-stepping applications, minimizing overshoot and resonance effects. The moderate weight of 2.32kg contributes to lower inertia, improving acceleration response and dynamic positioning speed. The five-phase design reduces torque ripple, enabling smoother rotation and quieter operation in sensitive automation environments. Rated for continuous duty at up to 0.75A per phase, the motor maintains stable thermal performance and consistent torque delivery under extended run times.

System integration leverages the standard mechanical interface of the 60mm flange diameter and 9.5mm shaft, enabling direct replacement or upgrade in existing drive assemblies. The five-wire configuration simplifies wiring harness design, reducing installation time and error risk. As part of the StepSyn Stepping Motors series by Sanyo Denki, the 103-8572-7041 is ideal for applications in pick-and-place machines, conveyor indexing, packaging equipment, and precision assembly systems. Its combination of high resolution, compact size, and robust construction meets the stringent demands of modern industrial automation platforms.
