Product Description:
The P21NSXC-LSS-NS-05 is a two-phase hybrid stepper motor manufactured by Pacific Scientific as part of the POWERMAX II P Motors series. Intended for open-loop positioning, it turns incoming pulse trains into indexed rotation, enabling repeatable motion on feeders, labeling heads, and compact gantry axes within automated equipment. The model follows standard construction practices, provides a NEMA mounting interface, and uses a receptacle connection that shortens installation time on the factory floor.
With a frame size of NEMA 23, the motor bolts to a 56 mm square face commonly found on linear stages and gearheads. A holding torque of 0.82 Nm keeps modest loads stationary when the axis is idle. Each winding is rated at 3.5 A, so the drive must supply that continuous phase current to realize the published torque curve. Electrical characteristics include 1.06 Ω of resistance and 2.3 mH of inductance; together these values limit rapid step rates and influence the voltage needed for high-speed operation. The motor passes a 500 VDC dielectric test for one minute, and its Class B insulation system withstands internal temperatures up to 130 °C while keeping the external case below 95 °C.
Each full step moves the shaft by 1.8 degrees, producing 200 discrete positions per revolution for direct coupling to lead screws or index wheels. Positioning error stays within ±1.5 %, limiting cumulative drift during multi-step sequences. The motor has an IP23 enclosure rating, allowing use in ventilated enclosures where water spray is absent yet airflow aids cooling. A 0.03 Nm detent torque restrains the rotor when the coils are de-energized, the operating window spans −20 °C to +40 °C, and 100 MΩ insulation resistance at 500 V confirms long-term dielectric stability.
