Product Description:
The 103H5210-0457 is a hybrid stepper motor produced by Sanyo Denki within the StepSyn Stepping Motors series. Designed for position-based motion duties, the unit converts pulse trains from an indexer or PLC into discrete shaft increments that advance machinery without feedback. Its miniature NEMA 17-style dimensions and standardized mounting provide a compact drive element for pick-and-place axes, labeling heads, and small conveyors in industrial automation.
With each electrical step, the rotor moves exactly 1.8°, a resolution that allows controllers to achieve 200 full-step positions per revolution without microstepping. When energized, the motor produces a holding torque of 0.37 N·m, which keeps light loads from drifting while the shaft is stationary. The phase windings draw 1.2 A per phase, which establishes the appropriate current limit for the driver stage and influences thermal rise. Each phase has a resistance of 3.3 Ω, keeping copper loss at the rated current modest enough to support extended duty cycles. The winding inductance is 3.4 mH per phase, which slows the current slew rate and limits the pulse frequency available before torque begins to decrease.
The windings have a nominal voltage of 4 V, which is consistent with their rated current and resistance. The square frame measures 42 mm across and mounts through M3 × 0.5 holes around a 22 mm pilot, helping maintain concentric alignment between the motor and a connected gearbox. The complete assembly has a mass of 0.37 kg, keeping the added load low when the motor is installed on a fast-moving gantry. Rotor inertia is 0.074 × 10⁻⁴ kg·m², allowing quick acceleration when the two-phase unipolar winding set receives high-speed pulse trains. The compact frame and low rotor inertia support rapid starts and stops in applications that require short, repeatable indexing movements.
