Engineered by Sanyo Denki, the 103H7126-07E0 features a motor type stepping motor design optimized for incremental position control. Its compact footprint and flange interface simplify mechanical integration, while the option for drive electronics option integrated or external allows adaptation to a variety of control architectures. With a drive method bipolar or unipolar capability and number of phases 2-phase, this motor addresses diverse application requirements in factory automation, CNC indexing, and robotics. The patented StepSyn technology ensures reliable operation under continuous load conditions and enhances overall system throughput.

Detailed technical specifications reflect the motor’s balance of size, torque, and electrical characteristics. The step angle 1.8° per step combined with step accuracy high yields fine resolution suitable for precise motion sequences. The motor delivers a holding torque of 0.5–2 Nm and operates at a rated current of 2–4 A per phase with a nominal rated voltage of 2–4 VDC. Its shaft diameter of 10–14 mm accommodates standard coupling interfaces, while the motor length of 75.8 mm and motor mass of 0.98 kg ensure a favorable power-to-weight ratio. The rotor’s dynamic behavior is characterized by a rotor inertia of 0.36 × 10^-4 kg·m², which supports rapid acceleration and deceleration.

Operational features emphasize performance under varied environmental and load conditions. The motor’s operating temperature range of -10°C to +50°C ensures reliable operation across industrial settings. Flange mounting via the mounting flange configuration provides mechanical stability and repeatable alignment. Whether driven in bipolar or unipolar mode, the motor maintains smooth motion profiles and low vibration due to its high step accuracy and carefully optimized electromagnetic design. Optional integrated drive electronics minimize external component count, reduce wiring complexity, and enhance noise immunity, supporting seamless integration into existing machine control systems.

System integration benefits from the motor’s standard interface and flexible drive options. The 103H7126-07E0 is compatible with a wide range of step motor drivers and controllers in industrial automation platforms. Its flange mount and standard shaft dimensions streamline mechanical coupling to gearboxes, lead screws, or belt drives. Target applications include pick-and-place machinery, rotary indexing tables, packaging equipment, and laboratory automation where precise position control, repeatable torque, and a compact form factor are critical. Designers can leverage the motor’s proven reliability and extensive technical documentation from Sanyo Denki to accelerate project timelines and ensure predictable system performance.
