103-7516-5530 by Sanyo Denki

The Sanyo Denki 103-7516-5530 stepping motor from the StepSyn Stepping Motors series by Sanyo Denki delivers precise motion control and rugged reliability for demanding industrial automation applications. Featuring a Step angle 1.8°, this device provides exceptional positioning accuracy and repeatability for CNC systems, robotic arms, and precision assembly lines. The motor generates a continuous Holding torque 1.2 Nm while maintaining thermal stability over prolonged duty cycles, ensuring consistent performance in high-throughput operations. Its compact profile and robust construction enable integration into confined machine spaces without sacrificing durability or noise suppression.

Technical specifications underscore the motor’s engineering pedigree: it operates at a Voltage rating 4.2V with a Current per phase 3A input, balanced through a Phase resistance 1.4 Ohms and Inductance per phase 3.5 mH design to optimize step response and minimize vibration. The bipolar design utilizes Phases 2 and includes a Rotor inertia 280 g·cm² for smooth acceleration profiles, while the Shaft diameter 8 mm accommodates standard couplings. The overall Length 76 mm and Weight 1.1 kg deliver a high power-to-weight ratio, and the Motor type Bipolar Stepper Motor classification ensures compatibility with common driver architectures. Built-in insulation meets Class B standards, and the motor withstands continuous operation across an Operating temperature -10 to 50°C range without performance degradation.

Operational features highlight thermal management and dynamic response: advanced cooling pathways within the housing reduce hotspot formation, enabling the motor to maintain torque output under sustained loads. The Sanyo Denki 103-7516-5530 exhibits low resonance and jitter during acceleration and deceleration phases, facilitated by its precisely engineered winding geometry and optimized inductance. Noise levels remain low across the speed range, supporting quiet operation in sensitive environments. The motor’s robust bearings and reinforced front flange mounting deliver mechanical stability, reducing end-play and ensuring repeatable motion over millions of cycles. Continuous operation at full load does not compromise the defined Holding torque 1.2 Nm, preserving positional accuracy in high-cycle-rate systems.

System integration is streamlined through compatibility with standard stepper drives and microstepping controllers, enabling engineers to implement advanced motion profiles and feedback algorithms. The motor’s footprint fits NEMA-compatible frames, simplifying retrofits and new machine designs in industrial automation. Ideal applications include CNC milling machines, 3D printing platforms, packaging equipment, and pick-and-place robots where precision, reliability, and long service life are critical. The combination of Sanyo Denki quality, StepSyn Stepping Motors series innovation, and the proven performance of part number 103-7516-5530 makes this motor a preferred choice for automated manufacturing systems seeking sustained accuracy and operational uptime.
