Product Description:
The M22NRXA-LNF-NS-00 is a two-stack hybrid stepper motor produced by Pacific Scientific within the POWERMAX II M Motors series. Built for positioning and speed-indexing duties in automated machinery, the unit converts digital pulse trains from a drive into precise angular motion so that actuators, slides, or small conveyors can move to repeatable locations without closed-loop feedback. The regular lead wire connection style simplifies field termination, and the enhanced construction type supports the thermal and mechanical loads found in pick-and-place heads, labelers, or syringe pumps.
The motor uses a NEMA 23 frame, so mounting holes and pilot dimensions match common 57 mm interface plates. Overall body length is 3.10 in, offering additional magnetic length for higher torque than single-stack models of the same frame. A stainless steel shaft with a diameter of 0.2500 in exits the front bearing and includes a ground flat to simplify coupler or pulley attachment. Motion resolution is set by a full-step angle of 1.8 degrees, so one electrical revolution equals 200 discrete steps and allows controllers to index linearly or by microstep for finer resolution.
Internal windings are insulated to Class B, 130 °C, so the motor can dissipate copper losses without degrading varnish or slot liners. Reliable service is maintained between ambient temperatures of -20 °C to +40 °C, covering most indoor factory environments. Coils withstand up to 340 Vdc impulse voltage, and insulation resistance remains at 100 MΩ to reduce leakage through the laminate stack. Position accuracy is held within ±1.5% of a single step, which is suitable for metering valves or small index tables without external feedback. A standard rotor and single-ended shaft keep inertia low, and the dual-stack magnetic circuit increases holding torque while maintaining smooth microstepping characteristics.
