Product Description:
Pacific Scientific’s M21NSXC-LNN-NS-02 is a two-phase step motor in the POWERMAX II M Motors series. Intended for open-loop positioning in indexing tables and general automation, it turns command pulses into fixed angular moves. The unit employs enhanced construction with a standard rotor and follows the NEMA mounting convention, so it fits directly into existing 23-frame brackets. An integral smooth, single shaft and the absence of feedback hardware reduce component count for applications that do not require encoder-based verification. This layout suits machines that rely on repeatable commanded steps rather than closed-loop position confirmation.
The motor occupies a NEMA 23 frame and has a 52.3 mm housing length, providing a compact footprint with sufficient magnetic length. Its winding type C and single-stack armature develop up to 1.02 Nm of holding torque for load retention at standstill. Motion increments are fixed at 1.8 degrees, giving 200 steps per revolution, while step accuracy remains within ±1.5%. A rotor inertia of 0.00001200 kg-m² supports high acceleration, and the 6.35 mm smooth shaft simplifies coupler alignment. Continuous operation is rated from -20 °C to +40 °C, which suits typical cabinet and machine-area conditions.
Windings use Class B, 130 °C insulation that tolerates up to 340 Vdc impulse voltage, with 100 megohms of insulation resistance measured at ambient temperature. External surfaces may reach 95 °C under full load, yet they remain below the thermal limit of the insulation system. Protection is classified as IP23, guarding against finger contact and light spray when the motor is installed inside a ventilated enclosure. The assembly weighs 0.68 kg, which helps keep moving-axis mass low. Power is delivered through a receptacle connector, and the NEMA flange, smooth shaft, and standard rotor geometry allow direct coupling to belts, lead screws, or gears without additional machining.
