103H7123-5740 by Sanyo Denki

The Sanyo Denki 103H7123-5740 is a high-precision stepping motor in the StepSyn Stepping Motors series, designed to deliver reliable motion control in demanding industrial automation applications. Built by Sanyo Denki, this compact unit offers 200W power output and 1 Nm holding torque, providing a robust balance of torque density and energy efficiency. It accommodates a wide input voltage range of 100-240V AC, enabling straightforward deployment across diverse electrical environments. The motor’s streamlined design incorporates both USB and Serial interfaces for flexible communication and integration with motion controllers and PLC systems. Its single-shaft configuration optimizes mechanical efficiency and simplifies coupling to driven loads.

Detailed technical specifications emphasize the motor’s adaptability and precision. The holding torque of 1 Nm ensures stable positioning under static loads, while its power output of 200W supports continuous duty cycles. A motor flange size of 56 mm and single shaft design facilitate direct installation into customized fixtures or gearboxes. The unit accepts an input voltage range of 100V AC up to 240V AC without requiring external transformers, reducing overall system complexity. Operational reliability is maintained through a specified operating temperature range of 0°C to +60°C, enabling performance in both climate-controlled facilities and harsher ambient conditions. The DIN rail-compatible mounting style simplifies installation within control cabinets and panel assemblies.

Operational features of the 103H7123-5740 highlight its suitability for precision automation. Its step-and-direction control scheme provides sub-micron positional resolution when paired with appropriate motor drivers. The motor exhibits low vibration and minimal acoustic noise, supporting high-speed indexing and continuous scanning motions. Power management is optimized to deliver consistent torque while minimizing heat generation, extending bearing life and reducing maintenance intervals. USB and serial connectivity streamline parameter tuning, allowing on-the-fly adjustments of acceleration profiles, microstepping modes, and current limits through dedicated configuration software.

System integration is straightforward whether used in robotics, CNC machinery, or packaging lines. The StepSyn Stepping Motors series conforms to IEC 60068 standards, ensuring compatibility with a broad ecosystem of industrial controllers. DIN rail mounting and standard flange dimensions accelerate prototyping and retrofit projects, while the dual communication ports support both legacy and modern automation platforms. Target applications include pick-and-place modules, turret indexing systems, laboratory instrumentation, and other motion-centric processes where precise positioning and reliable operation are critical.
