Product Description:

The 103H7126-0780 from Sanyo Denki, is a stepping motor (high-performance) from the StepSyn Stepping Motors class, designed to offer powerful, precise motion regulation in a powerful yet compact form. With a motor size of 56 mm square and a length of 75.8 mm (millimeters), this unit fits easily into space-restricted applications while delivering impressive output. It can deliver a holding torque class of 1.27 N·m and operates at a specified current of 3 A (Ampere) per phase, with a standard step angle of 1.8°, making it ideal for accurate and repeatable positioning in automated systems. This motor is designed to work seamlessly with drivers offering advanced control functions. It supports pulse input modes, including 1- or 2-input operation, low vibration mode, and step division mode for enhanced smoothness and resolution. Users can also configure settings such as initial excitation phase, motor type, operating current, and step angle, allowing for flexible integration into a wide range of systems.

The Sanyo Denki 103H7126-0780 includes a full suite of protection features, such as overheat detection, overcurrent protection, power supply voltage monitoring, and error detection for wiring and command signals. With non-volatile memory checksum verification, the system ensures safe and stable performance even after power cycles. Signal inputs and outputs are handled via photocoupler insulation, providing noise immunity and electrical isolation. These include power-down input, step angle selection, and alarm output, with open-collector design for easy interfacing.

This motor is built for reliability and performance, backed by Sanyo Denki’s robust engineering. Now available at Wake Industrial, the 103H7126-0780 offers a smart, compact solution for industrial automation needs, complete with expert support and a one-year warranty. Throughout, the control keeps operative even when the power stage triggers off by use of any form of exterior voltage connected to the control circuit unit.
