Product Description:
The M22NRXD-LNF-NS-00 is a two-phase stepper motor manufactured by Pacific Scientific within the POWERMAX II M Motors series. As a positioning element, it advances one discrete angle per input pulse, allowing machine tools, dispensers, and small conveyors to achieve repeatable incremental motion without closed-loop feedback. This operating method suits applications that need predictable indexing and straightforward drive integration.
The laminated stator is packaged in a NEMA housing with an overall depth of 3.10 in. Its width is 2.25 in, and the 2.625 in bolt circle aligns with standard NEMA faceplates. A NEMA 23 frame code and a standard lead-wire connection simplify use with existing drives, while the eight-pin receptacle carries phase, shield, and chassis leads. The winding is type D and uses two stacks to increase torque without adding rotor length. Each full step measures 1.8 degrees and is held by a detent torque of 0.12 Nm. This resolution gives 200 discrete positions per revolution and maintains ±1.5% step accuracy. Insulation is Class B at 130 °C with 100 MΩ resistance and a 340 Vdc dielectric rating, allowing operation on most unipolar or bipolar drives. No feedback device is fitted, so commutation is based only on commanded pulses.
The unit weighs 1.13 kg and supports up to 58 N of axial load and 89 N of radial shaft load. It uses a single 0.2500 in diameter shaft that projects 0.75 in, and a 0.50 in flat helps with coupler attachment. The shaft is a standard rotor style with a single-ended output. Operating limits span -20 °C to +40 °C, with Class B insulation providing margin for additional self-heating. The motor mounts by the NEMA face and uses an enhanced laminated core to improve magnetic density during continuous duty.
