103H89223-5243 by Sanyo Denki

The 103H89223-5243 stepping motor from Sanyo Denki is a high-performance solution within the StepSyn Stepping Motors series, engineered for demanding industrial automation tasks. This motor features a TEFC enclosure type that ensures protection against dust and moisture, while its IE3 efficiency class design minimizes energy losses and operational costs. Rated for 380V operation, with a dual-voltage option of 220/380V models, it operates at a steady 50 Hz frequency for precise speed control. With power ratings available in 1.5, 5.5, 7.5, 11, 22, and 45 kW, this stepping motor accommodates a broad range of torque requirements. The motor’s robust fan cooled thermal management system ensures reliable performance under continuous load.

Technical capabilities of the 103H89223-5243 are anchored by its impressive mechanical and electrical specifications. The allowable thrust load of 100 N and allowable radial load of 290 N accommodate heavy-duty axial and radial forces. It maintains stable operation at a rated current of 6 A and a mass of 10.5 kg, supporting dynamic response without excessive inertia. The motor incorporates a lead wire connection type for flexible installation and connectivity. Its 4-pole configuration (with variants offering 2 poles) enables smooth step resolution and reduced vibration. The B3 shaft mounted design and output shaft with key ensure secure coupling to driven equipment, while enduring overvoltage conditions at 50/60 Hz for one minute to validate insulation integrity.

Operational features of this stepping motor deliver significant benefits for system designers and end users. The TEFC enclosure type combined with fan cooled operation prevents dust ingress and optimizes heat dissipation, extending component life. An IE3 efficiency class rating not only reduces electricity consumption but also lowers thermal stress on internal windings, contributing to maintenance-free runtime. The dual-voltage capability (380V or 220/380V) allows adaptation to existing power infrastructures without additional transformers. With a robust mass of 10.5 kg, the motor resists vibrational disturbances, ensuring consistent positional accuracy under load. The integrated output shaft with key simplifies mechanical coupling and torque transmission in conveyor, packaging, and CNC applications.

Integration and application of the 103H89223-5243 stepping motor are straightforward thanks to its standardized mounting and connection features. The B3 shaft mounted configuration and lead wire terminals facilitate quick installation on machine frames and control panels. Its broad power rating range (1.5 to 45 kW) makes it suitable for use in robotic indexing tables, printing machinery, textile looms, and automated assembly lines. Compliance with IE3 efficiency class and TEFC enclosure standards ensures compatibility with rigorous industrial regulations and operational environments. Designed for seamless integration, the StepSyn series motor delivers precision, reliability, and scalable performance across diverse automation systems.
