103H6703-50XE43
by Sanyo Denki
The Sanyo Denki 103H6703-50XE43 is a precision stepping motor from the StepSyn Stepping Motors series, designed and manufactured by Sanyo Denki for demanding industrial automation applications. This 2-phase synchronous motor operates via a condenser and resistor, delivering constant rotation speed proportional to the AC power frequency. It provides high torque at ultra-low speeds, making it ideal for processes that require precise, slip-free motion under varying loads.
Incorporating robust engineering, the 103H6703-50XE43 withstands an ambient temperature range of -10°C to +50°C and maintains reliable operation in 20%–95% RH (no condensation) environments. It has an insulation resistance of at least 100 MΩ at 500 V DC between the winding and frame, ensuring electrical safety and longevity. The motor endures a withstand voltage of 1 kV AC (50/60 Hz) for 1 minute with leakage current not exceeding 1 mA. Mechanical precision is ensured by controlling axial play to ≤0.075 mm, while the winding temperature rise remains ≤80 K under normal operating conditions.
The 103H6703-50XE43 is directly driven by commercial AC power—requiring no external driver circuit—simplifying system integration and reducing component cost. Its motor conversion from a conventional stepping motor to synchronous operation enhances efficiency and reliability. Compatible with conveyors, printers, cryopump freezers, and a wide range of industrial devices, it delivers stable, slip-free performance. The high insulation resistance and controlled temperature rise contribute to exceptional durability, making this motor a cost-effective choice that maximizes uptime and productivity in industrial applications.
