103-770-0167 by Sanyo Denki

The 103-770-0167 from Sanyo Denki stands as a precision-engineered component within the StepSyn Stepping Motors series, designed for industrial-grade automation. This bipolar stepping motor features a Step Angle of 1.8° and delivers Steps per Revolution totaling 200 steps for high-resolution positioning. With a Motor Length (mm) of 75.8 and a compact Mass (kg) of 0.98, the unit balances torque output and form factor for seamless integration. Its rated electrical parameters include a Rated Voltage of DC 5.1 V and a Rated Current (a/phase) of 2, ensuring compatibility with standard drive electronics.

Technical capabilities of the 103-770-0167 stepping motor are underscored by its robust Winding Type—a bipolar coil topology—and a Winding Inductance (mH/phase) of 9.1 that optimizes current control and response time. The Wiring Resistance (ohms/phase) of 2 offers predictable thermal characteristics under continuous operation. Mechanical inertia is minimized with a Rotor Inertia (x10^-4 Kg-m²) of 0.36, yielding rapid acceleration and deceleration profiles. Holding torque reaches 1.27 Nm at 2-phase energization, ensuring stable loads during standstill. The motor’s design accommodates both a Single Shaft Model No (103H7126-5740) and a Dual Shaft Model No (103H7126-5710), expanding its adaptability across diverse machine architectures.

Operational features emphasize reliability and ease of use in demanding environments. The Connector Type is a 6-pin connector that simplifies wiring and reduces installation time, while the Lead Wire Type offers direct lead connections for straightforward harness integration. Vibration and noise are minimized through precise manufacturing tolerances, resulting in smooth incremental motion ideal for CNC routers, 3D printers, and pick-and-place systems. The motor’s compact mass and length reduce inertia effects on the overall drive train, enhancing energy efficiency and extending the lifespan of downstream components. A tightly controlled step angle error and consistent holding torque improve repeatability, reducing cumulative indexing errors in multi-axis setups.

Integration into broader automation systems is facilitated by the motor’s standard electrical interface and mounting provisions. Engineers can mount the 103-770-0167 using its industry-standard dimensions and attach pulley or gear systems directly to the shaft for belt-driven configurations. This stepping motor excels in applications such as robotics, conveyor indexing, medical instrumentation, and precision lab automation. By combining high torque density, low inertia, and straightforward connectivity, the 103-770-0167 provides a versatile solution for modern industrial motion control.
