Product Description:
The 103H8222-0441 is a two-phase hybrid stepping motor produced by Sanyo Denki for the StepSyn Stepping Motors series. It converts discrete pulse commands from indexers or PLC motion modules into precise shaft increments, allowing equipment such as pick-and-place heads, small gantries, and metering pumps to position loads without feedback devices. By advancing the rotor in fixed electrical steps, the motor simplifies open-loop positioning tasks and reduces sensor wiring in compact industrial assemblies.
The motor delivers a holding torque of 4.13 N·m, allowing fixtures or lead-screw tables to remain stationary against static loads when the coils are energized. Each command pulse advances the shaft by 1.8° per step, so a full revolution requires 200 pulses and resolution calculations remain straightforward for motion control. The phase windings are rated at 2 A per phase; a compatible drive can supply this current to achieve the rated torque without overheating the coils. A phase inductance of 15 mH per phase shapes the current rise time, influencing how quickly the rotor can accelerate before mid-band resonance appears. The electrical resistance is 4.0 Ω per phase, which affects copper losses and helps determine the supply voltage needed for high-speed operation.
The square housing measures 86 mm across the frame and has a body length of 92.2 mm, fitting NEMA 34 mounting patterns while conserving installation space. The motor has a total mass of 2.5 kg, which adds damping to systems that are sensitive to vibration. Its rotor inertia is 2.9 × 10⁻⁴ kg·m², and the connected load inertia should be considered when setting acceleration profiles for an effective step response. The shaft has a diameter of 12 mm and protrudes 30 mm, while a pilot diameter of 73.025 mm centers the motor on compatible gearheads. The housing includes 5.35 mm mounting holes, and AWG 22 leads exit the housing with a minimum length of 305 mm, providing adequate reach to nearby terminal strips without splicing.
