Product Description:

The P2HNRXC-LSN-NS-03 hybrid stepper motor is produced by Pacific Scientific for the POWERMAX II P Motors series. Built around a NEMA mounting interface, the device translates pulse commands from a drive into precise incremental rotation, making it suitable for indexing tables, small gantries, and packaging equipment where closed-loop feedback is not required. A smooth shaft and standard construction simplify coupling to timing pulleys or rigid couplers in space-constrained assemblies. This open-loop configuration suits applications that rely on repeatable pulse-based positioning rather than encoder-based correction.

The motor uses a NEMA 23 frame, so its 2.25-inch square face matches common gearboxes and brackets without custom hardware. Each full step advances the rotor by 1.8 degrees, and those increments accumulate into 200 discrete steps per revolution, enabling straightforward micro-stepping ratios inside the drive. A detent torque of 2.5 oz-in (0.018 Nm) resists unintended movement when the windings are unenergized, while the low rotor inertia of 0.0010 oz-in-s² supports rapid acceleration in high-cycle machines. The windings use Class B, 130°C insulation, which provides thermal tolerance for normal industrial duty. Standard lead wires exit through a receptacle for quick connection to screw terminals or IDC headers, and no feedback devices are fitted, which keeps wiring simple.

Heat from copper losses reaches the housing through a thermal resistance of 6.6 °C/W, so forced airflow can raise the continuous torque envelope when duty cycles are demanding. The stator lamination pack uses a Half Stack arrangement, which shortens the overall length for installations with limited depth while reducing magnetic detent force. Rated operation spans -20°C to +40°C, permitting the motor to start reliably in unheated facilities and to run near standard control-panel temperatures. The motor also has an insulation resistance of 100 MΩ at a 340 V dc test voltage, supporting stable electrical isolation during storage and operation.
