Product Description:

The P21NSXC-LNS-NS-02 is a hybrid stepper motor produced by Pacific Scientific within the POWERMAX II P Motors series. This NEMA-style unit is intended for positioning and speed indexing tasks in industrial automation where open-loop motion control is sufficient. Its single-shaft design, standard construction, and receptacle connections make it a straightforward choice for compact actuators and gantry axes that rely on precise incremental rotation.

This model has a detent torque of 0.028 Nm, which helps the motor resist minor external disturbances when it is de-energized. The mechanical interface follows the NEMA 23 frame envelope, so it fits common mounting plates used for this motor size. Class B insulation supports a maximum winding temperature of 130 °C, while the windings are rated for 340 Vdc insulation voltage and 100 megohms of resistance to ground. Continuous duty is permitted between -20 °C and +40 °C, which suits most cabinet or machine-frame installations. Each electrical step advances the rotor by 1.8 degrees, resulting in 200 discrete positions per revolution with its single-stack design and standard rotor laminations. The motor also uses a C-style winding that balances speed and torque, and a two-pin receptacle routes phase current to the coils.

Position fidelity is held to ± 1.5 % step accuracy, allowing predictable cumulative error over long motion sequences. Thermal behavior is characterized by a winding-to-ambient path of 5.5 °C/W, so added airflow or heat sinking may be useful if duty cycles raise coil temperature toward the insulation limit. The motor uses a 2-phase architecture, and its single stack, standard rotor, and NEMA mounting arrangement simplify integration. It also has a single output shaft and standard construction, and it operates without a feedback encoder.
