Product Description:

The P2HNSXC-LSN-NS-02 is a hybrid stepper motor manufactured by Pacific Scientific as part of the POWERMAX II P Motors series. The unit fills positioning or indexing roles in automated equipment where compact torque delivery is required. Its standard construction uses a receptacle for coil leads, includes a standard rotor core, and features a smooth shaft that accepts couplings without additional machining. Because the encoder option is set to no feedback, motion is controlled strictly by commanded step counts. A NEMA mounting footprint lets the motor fit existing machine layouts that share the same bolt circle.

With a NEMA 23 frame size, the motor has a 57 mm face dimension, and the half-stack lamination keeps overall length short without sacrificing static torque. In parallel winding mode, it produces 61 oz-in (0.43 Nm) of holding torque, a value important for tables or lead screws that must resist back-drive at rest. The copper windings carry an insulation system rated Class B, 130°C, and inter-turn dielectric strength is specified for up to 340 Vdc so the motor can tolerate high bus voltages from microstepping drives. Phase inductance is 2.3 mH, balancing current rise time against electromagnetic damping for smooth low-speed motion.

The electrical profile is built around 2 phases driven in parallel at a rated phase current of 2.5 A and a phase resistance of 0.84 Ω. Combined with the C winding code, this configuration limits copper loss while keeping torque linear through the commanded range. Each electrical cycle advances the rotor by 1.8 degrees, giving 200 discrete steps per revolution with a stated step accuracy of ±1.5%. An insulation resistance of 100 megohms guards against leakage paths in humid settings, and reliable operation is maintained from -20 °C to +40 °C ambient.
