Product Description:
The 103H6332-0340 is a three-phase stepping motor manufactured by Sanyo Denki for the StepSyn Stepping Motors series. Intended for open-loop positioning in pick-and-place heads, indexing tables, and compact conveyors, the unit translates command pulses into repeatable angular increments that synchronize mechanical motion with PLC timing. Its compact housing and low moment of inertia make it well suited to light industrial automation where precise incremental control is required without feedback devices. The motor can support applications that require predictable movement based on pulse count and direction signals from a compatible controller.
Its basic step resolution is 1.2°, so 300 full-step pulses rotate the shaft through one revolution and provide a straightforward basis for microstepping control. The winding is arranged for a bipolar, three-phase drive system and draws 3 A per phase; its 1.6 mH-per-phase inductance smooths the current rise during microstepping. Copper resistance measures 1.3 Ω per phase, which helps determine the voltage required from the driver to reach the rated current. A holding torque of 0.44 N·m keeps loads stationary whenever the windings are energized, while a rotor inertia of 0.12 × 10−4 kg·m² supports rapid start-and-stop cycles. The frame has an IP40 protection rating, which guards against the entry of solid objects larger than 1 mm when the motor is installed in a sheltered location.
Mechanical mounting uses a 50 mm square flange that can be attached to a suitable motor bracket, and the overall depth is 51.3 mm, allowing installation behind narrow panels. The motor has a mass of 0.5 kg, which reduces the overhung load on linear slides when it is mounted in a cantilevered position. A smooth, circular output shaft accepts set-screw or clamping couplings without additional machining. The permitted operating temperature range is -10 to +50 °C, supporting use in a variety of indoor industrial settings. Ambient humidity may range from 20% to 90% RH without condensation, so moisture must not accumulate on the housing or electrical connections. The compact flange, shallow housing, and low mass allow the motor to fit into machinery with limited mounting space.
