SH1602-5240

The SH1602-5240 stepping motor from Sanyo Denki belongs to the F SANMOTION Stepping Motors series, delivering industry-leading precision in a compact form factor. This motor offers a holding torque of 1.28 N·m and a rated current of 2 A/phase, ensuring sufficient power for a wide range of motion control tasks. With a motor length of 54 mm and a motor mass of 0.8 kg, it strikes an optimal balance between torque density and footprint, making it ideal for space-constrained installations. The motor’s protection grade of IP40 and operating temperature range of 10°C to +50°C guarantee reliable performance in standard industrial environments with moderate exposure to dust and temperature variations.

Technical capabilities of the SH1602-5240 are defined by precise mechanical and electrical characteristics. The winding inductance of 6.1 mH/phase and winding resistance of 1.65 Ω/phase optimize current flow for rapid torque response. A low axial play of 0.075 mm (under 10 N) and minimal radial play of 0.025 mm (under 5 N) maintain shaft stability during acceleration and deceleration. The motor’s rotor inertia of 0.4 × 10⁻⁴ kg·m² contributes to smooth dynamic performance, while a shaft runout of just 0.025 mm reduces mechanical backlash. These specifications, combined with a step size of 0.9°, enable highly repeatable positioning in demanding motion control applications.

Operational features and benefits include robust mechanical resilience and environmental tolerance. The SH1602-5240 withstands impact resistance of 490 m/s² for 11 ms (half-sine wave) and endures vibration resistance from 10 to 500 Hz with 1.52 mm amplitude at 147 m/s², ensuring stability during machine startup and shuttle movements. The integrated bipolar winding design ensures balanced phase currents for minimal noise and heat generation. With IP40 protection, the motor resists ingress from solid particles larger than 1 mm, and its operating temperature window supports continuous duty under typical factory conditions. These features translate to reduced downtime, extended service intervals, and consistent control accuracy across production cycles.

Designed for seamless integration into industrial automation systems, the SH1602-5240 pairs readily with Sanyo Denki DC stepping drivers and third-party stepper controllers. Its standardized 60 mm flange with four M4 mounting holes simplifies mechanical attachment, while AWG 22 lead wiring ensures compatibility with common cabling practices. The motor’s precise step increment and torque characteristics make it ideal for applications such as pick-and-place robots, conveyor indexing, labeling machines, and medical diagnostic equipment. By combining compact dimensions, high torque density, and proven reliability, the SH1602-5240 empowers engineers to optimize motion control solutions for both new installations and retrofit projects.
