103H7126-0447 by Sanyo Denki

The 103H7126-0447 stepping motor by Sanyo Denki is a precision motion device from the StepSyn Stepping Motors series, engineered for industrial automation applications. This bipolar Stepper Motor operates at Nominal Voltage: DC 24V with a Rated Current: 4 A/phase, delivering a Step Angle: 1.8° for fine positional control. It produces a holding Torque: 12.7 kg/cm and features a Winding Inductance: 0.85 mH/phase for rapid current response. The compact Motor Length: 41.8 mm and lightweight design simplify integration into space-constrained systems. Designed for harsh environments, it supports an Operating Altitude: up to 1000 m above sea level and complies with stringent industrial standards.

Performance is optimized through low coil inductance and robust winding architecture, enabling swift torque generation and minimal step settling time. The motor’s dual-phase configuration handles rapid current transitions up to Rated Current: 4 A/phase while maintaining thermal stability. Mechanical resilience is ensured by an Allowable Thrust Load: 20 N axial capacity, safeguarding shaft integrity under external loads. Shock tolerance is rated at Shock Resistance: 500 m/s², 11 ms, half sine wave with Shock Test Repetitions: 3 shocks per direction on X, Y, Z, guaranteeing uninterrupted operation in vibration-prone environments. The precise Step Angle: 1.8° combined with high torque-to-inertia ratio delivers smooth acceleration and deceleration profiles crucial for indexing and positioning tasks.

Reliability is reinforced by stringent quality control and a robust housing that resists mechanical stress and contamination. The short Motor Length: 41.8 mm and standardized mounting flange facilitate seamless integration with a wide range of drives and motion controllers. The 103H7126-0447 excels in applications such as pick-and-place robotics, conveyor indexing, and precision dispensing, where repeatability and torque consistency are paramount. Its ability to maintain performance at elevations up to Operating Altitude: 1000 m extends its use to high-altitude manufacturing and laboratory environments. Overall, this stepping motor offers a balanced combination of precision, durability, and ease of integration for demanding industrial automation systems.
