Product Description:
The 103H8222-6340 is a hybrid stepping motor produced by Sanyo Denki as part of the StepSyn Stepping Motors series. The unit converts pulse trains from a drive into discrete rotor positions, making it suitable for indexing tables, pick-and-place heads, and other automation axes that require repeatable open-loop motion. Its two windings use a bipolar configuration, allowing the connected drive to control current in both directions through each phase.
A basic step angle of 1.8° divides each full rotor revolution into 200 mechanical increments, providing fine positioning without an encoder. The motor generates 5.09 N·m of holding torque, so fixtures remain stationary when the drive is energized but not stepping. The phase windings draw 6 A per phase, and the stepper drive must supply this rated current to achieve the stated torque. The copper resistance is 0.35 Ω per phase, which contributes to resistive losses and heat buildup during continuous operation. With a rotor inertia of 2.9 × 10⁻⁴ kg·m², the motor supports responsive indexing while limiting the potential for excessive overshoot. The windings have an inductance of 2.7 mH per phase, which influences the current rise time as the drive switches between steps. Power is supplied through AWG 18 lead wires, while the single shaft has a 4 × 4 × 25 mm key for positive torque transfer to pulleys or couplings.
The square mounting flange measures 86 mm and corresponds to the NEMA 34 format used by many gearbox and bracket patterns. The body has an overall depth of 92.2 mm, allowing the motor to fit within compact machinery enclosures while leaving room for its lead-wire routing. The enclosure carries an IP43 rating, protecting internal components against solid objects larger than 1 mm and water spray while permitting convection cooling. The motor has a total mass of 2.5 kg, so the mounting surface must provide adequate support without excessive deflection. Its aluminum housing provides a rigid structure for the stator and bearings during repeated acceleration and deceleration cycles.
