Product Description:
The P22NRXA-LSN-NS-02 stepper motor is manufactured by Pacific Scientific and belongs to the POWERMAX II P Motors series. Designed for open-loop positioning tasks in machine tools, pick-and-place heads, and indexing conveyors, the unit converts digital step commands into incremental rotary motion without an internal feedback device. Its open-loop design suits applications where the controller tracks position by counting steps. As a standard-construction two-phase motor, it fits the NEMA mounting pattern commonly used across compact automation platforms.
Mechanical dimensions are set by its NEMA 23 frame, while a smooth shaft interface simplifies coupling to pulleys or gears. Two rotor stacks and two electrical phases give the motor a 200-step-per-revolution pattern, with each step covering 1.8 degrees. The holding torque is 1.39 Nm, and a residual 0.05 Nm detent torque remains when the coils are de-energized. The machine controller must supply up to 6.5 A per winding through regular lead wires that terminate in a receptacle. This current capacity lets the windings develop the magnetic field needed for rated holding performance at standstill. Winding type A has 0.42 Ω of resistance and 0.8 mH of inductance, values that affect driver voltage selection and current-rise rates. The NEMA mounting style and standard rotor design fit compact automation platforms that use common mounting hardware.
Environmental limits protect coil insulation and coatings. The housing is rated IP23, so it resists ingress and falling water during indoor service. The windings use Class B, 130°C insulation and maintain at least 100 MΩ resistance when tested at 500 V, while dielectric integrity withstands 340 Vdc. Continuous duty is allowed as long as external surfaces stay below 95 °C and ambient air remains in the range of -20°C to +40°C. The motor maintains step accuracy of ±1.5 % across that temperature span. Indoor installation is still important because the enclosure is not intended for washdown areas or direct outdoor exposure.
