Product Description:
The P22NSHS-LNN-NS-02 is a two-phase hybrid stepper motor produced by Pacific Scientific for the POWERMAX II P Motors series. In automated pick-and-place stations, small conveyors, and indexing tables, it converts pulse commands into incremental shaft movement for open-loop positioning. This operating method provides repeatable step-by-step motion without requiring separate feedback hardware. Because it is a hybrid stepper design, the motor combines fine angular resolution with straightforward drive control in general automation equipment. It is intended for applications that need controlled positioning rather than continuous speed regulation from a servo loop. A smooth single shaft extends from the front face for direct coupling to gears or pulleys in compact machine layouts.
The rotor uses standard laminations and is built in a NEMA 23 frame, which fits common mounting patterns for compact motion systems. Its two-stack magnetic circuit produces 200 full steps per revolution, so each step equals 1.8 degrees and step accuracy remains within ±1.5%. Electrical connection is provided through a 4-lead parallel arrangement that supports full-step and microstep drive modes. Insulation resistance is 100 megohms under ambient test conditions, and dielectric strength is rated to 340 Vdc. This format is common in stepper applications that need predictable indexing and simple wiring between the motor and the drive. The motor is supplied without encoder feedback, which keeps the wiring straightforward.
The thermal system is rated at Class B, 130 °C. Housing temperature is limited to 95 °C to reduce heat transfer to nearby parts during continuous operation. The permitted ambient range is -20 °C to +40 °C, and the enclosure carries an IP23 rating for protection against finger contact and light sprays when the motor is installed inside machinery. The output shaft has a diameter of 6.35 mm and a smooth profile, which matches common couplings and pulleys. A standard flange pattern allows mounting to common machine interfaces used for this motor class.
