Product Description:

The M22NSXA-JDN-HD-02 is a hybrid stepper motor manufactured by Pacific Scientific for the POWERMAX II M Motors series. It serves in industrial automation tasks that need repeatable incremental motion, such as packaging lines, pick-and-place gantries, and semiconductor handlers. The motor converts electrical pulse trains into mechanical rotation, delivering indexed movement without continuous servo feedback while maintaining high torque at low speeds. This operating method makes it suitable for positioning tasks where predictable step response and stable low-speed performance are more important than full closed-loop servo control.

Internally, the motor uses the enhanced construction type and a two-stack stator to produce uniform torque at its 1.8 degrees fundamental step angle. This base angle and the ±1.5% step accuracy yield 200 discrete positions per revolution. A factory-mounted 500 LPR encoder supplies incremental feedback, and its quadrature-with-index format with single-ended outputs operates up to 100 kHz when powered by 5 VDC. Power and signal lines land on a receptacle, and the winding coded A matches standard drive currents. Mechanical fit is set by the NEMA 23 frame, NEMA face mounting, and a double smooth shaft that can couple to loads on either end. This arrangement supports compact machine layouts that need straightforward electrical connection and flexible shaft access.

Thermal and dielectric limits support reliable service. The windings carry Class B 130 °C insulation, withstand 340 Vdc impulse voltage, and offer 100 Megohms resistance at room temperature to minimize leakage. Continuous duty is allowed from -20 °C to +40 °C, matching typical control-cabinet climates. A low-inertia rotor shortens acceleration times, which benefits light indexing tables and other applications with frequent starts and stops. The enhanced build also helps the motor resist vibration, and the receptacle connector allows connection and removal without disturbing fixed conduit runs.
