Product Description:

Pacific Scientific manufactures the P22NSXC-LNN-NS-02 hybrid stepper motor in its POWERMAX II P Motors series. The device converts discrete drive pulses into controlled incremental motion, making it suitable for pick-and-place axes, indexing tables, and other positioning tasks in automated machinery. No feedback device is integrated, so the drive must count commanded steps for position verification.

The motor conforms to the NEMA 23 frame format, and its standard construction houses two magnetic stacks that deliver a holding torque of 1.43 Nm. Each full step advances the rotor by 1.8 degrees, producing 200 steps per revolution with a ±1.5% accuracy window. During energized standstill, the rated phase current of 3.1 A flows through C-type windings whose 1.56 Ω resistance and 3.9 mH inductance balance torque production with drive bandwidth. The laminated rotor presents 0.05 Nm of detent torque and a 0.025 × 10⁻³ kg·m² inertia, so acceleration is not hindered. Electrical insulation is Class B to 130 °C, verified by a 500 VDC one-minute dielectric test and a 340 VDC insulation voltage rating, while leakage is limited to 100 MΩ. A single smooth 6.35 mm shaft is supported by ball bearings and may accept 90 N of radial load. Connections are made through a receptacle, and the enclosure meets IP23 for drip protection.

With a body length of 78.8 mm and a mass of 1.13 kg, the motor occupies a compact envelope while keeping structural strain low on linear carriages. It tolerates ambient temperatures from -20 °C to +40 °C, and the external surface may rise to 95 °C without exceeding design limits. The assembly is ventilated rather than sealed, so direct liquid spray should be avoided. The specified rotor type and winding code remain unchanged, and the shaft stays single-ended for direct coupling to pulleys or lead screws.
