Product Description:

The M22NSXC-LSN-NS-03 stepper motor is manufactured by Pacific Scientific as part of the POWERMAX II M Motors series. Built on an enhanced construction platform, the motor uses a standard rotor with a smooth shaft and NEMA flanges to fit compact indexers, small gantry axes, laboratory dispensers, and light-duty assembly lines. Stepper operation converts controller pulse trains into fixed angular motion, so many positioning tasks can be handled without a separate feedback device. That operating style is useful in equipment where repeatable incremental movement and straightforward electrical integration are more important than closed-loop servo control.

It uses a two-phase, two-stack circuit. A detent torque of 0.12 N-m indicates the static resisting torque available with the coils de-energized. The NEMA 23 frame fits common 57 mm mounting patterns. Under rated current, the rotor delivers 1.68 N-m of holding torque for moderate inertia loads. Class B, 130 °C insulation supports normal thermal loading, and a dielectric strength of 340 Vdc provides isolation to ground. Insulation resistance is 100 megohms at ambient. In parallel, the winding has 3.1 mH inductance, 0.78 Ω resistance, and a current draw of 3.1 A DC, while series wiring changes those values to 12.4 mH, 3.1 Ω, and 1.6 A DC. The motor does not include a feedback device and uses a receptacle for power leads.

Ambient operation is specified from -20 °C to +40 °C, so the motor can start in cold conditions and run in typical enclosed panels. With a step angle of 1.8°, the rotor provides 200 full steps per revolution, and microstepping subdivides that base increment for smoother motion. Step accuracy is rated at ±1.5%, which helps the motor maintain consistent indexing from command to command. The C winding code aligns the copper fill with the stated electrical values. That arrangement suits indexing tables and transfer mechanisms that rely on repeatable step commands rather than continuous speed correction.
