103-746-1 by Sanyo Denki

The Sanyo Denki 103-746-1 stepping motor represents a robust member of the StepSyn Stepping Motors series, combining precision motion control with industrial-grade durability. Engineered to meet the rigorous demands of automated systems, this steel-constructed motor delivers consistent rotational accuracy for a broad range of positioning tasks. Its coarse thread design and imperial measurement standard facilitate straightforward integration into legacy equipment and custom assemblies. The motor’s structural integrity is assured by adherence to ASTM A307 guidelines, offering confidence in long-term mechanical reliability. Optimized for continuous operation, the 103-746-1 excels in high-throughput environments requiring repeatable, stable motion profiles.

The technical foundation of the 103-746-1 is defined by a set of critical parameters engineered for performance and reliability. It incorporates a Diameter-thread Pitch of 1/2-13 coarse thread for secure mounting interfaces and a Finishing of Plain surface to minimize alignment deviations. Constructed from Material: Steel, the device achieves a Grade A classification under Specification: ASTM A307 standards, confirming its suitability for industrial applications. The motor operates on a Voltage of 24 V DC supply and employs Insulation class F winding protection to withstand thermal cycling. Using the Imperial (Inch) System Of Measurement, it features a Thread Type of Coarse and measures Length of 10 inches from flange face to shaft end. Each unit is identified by PSR: 1014-C2P-050010000 for traceable quality control and maintenance tracking.

Operational performance of the 103-746-1 is tailored for demanding factory conditions. The motor supports continuous duty cycles, maintaining torque consistency across extended run-times without degradation. It is rated for operation within an ambient temperature range of 0 to +40 °C and up to 80% relative humidity, delivering dependable functionality in both enclosed and semi-protected installations. The sturdy steel housing, combined with an IP65 protection category, ensures resistance to dust ingress and light water exposure. The coarse 1/2-13 thread interface simplifies assembly and disassembly for maintenance or system reconfiguration, reducing machine downtime.

System integration of the 103-746-1 is seamless with industrial automation controllers, PLCs, and motion control modules common in manufacturing lines. Its compatibility with standard 1/2-13 mounting arrangements and 24 V DC power rails allows for direct replacement of legacy stepper motors. The motor’s precise step angle and low backlash thread coupling make it ideal for applications such as pick-and-place machines, indexing tables, labeling systems, and small-format CNC routers. Designed for high uptime and minimal maintenance, the Sanyo Denki 103-746-1 serves as a reliable solution for engineers seeking robust, accurate, and easily integrable stepping motor performance in complex automation scenarios.
