Product Description:
Pacific Scientific's M22NRXD-LNN-NS-00 belongs to the POWERMAX II M Motors series. It is a NEMA 23 hybrid stepper motor used for indexing or holding machine elements in automated assembly stations, inspection fixtures, and light material-handling axes. The device converts commanded current pulses into repeatable angular motion without requiring a feedback transducer. This operating method makes it suitable for applications where repeatable step positioning and straightforward pulse control are more important than closed-loop servo behavior.
The rotor advances in 1.8 degrees increments, giving 200 steps per revolution so a controller can translate pulse counts directly into motion. In parallel wiring, the phase current is 2.5 A, and the phase resistance is 1.22 Ω. A passive detent torque of 0.12 N·m helps resist unintended movement when the coils are off, which supports position holding during idle periods. The body depth measures 78.7 mm, allowing the motor to fit in tight spaces while still providing useful torque for compact mechanisms. With only 0.000025 kg·m² of rotor inertia, the shaft can accelerate quickly, which supports short move cycles on labeling heads, indexing devices, and small XY tables.
The motor operates in ambient temperatures from -20 °C to +40 °C, which suits many indoor industrial installations. The shaft can tolerate an axial load of 58 N, and the motor can also support direct coupling to light transmission components when loads stay within the stated limits. Connection is made through leadwires, and the enhanced construction includes 340 V DC insulation capability with 100 MΩ resistance for dependable electrical isolation. At 1.13 kg, the two-stack motor remains light enough for moving-axis use while still offering enough mass to help limit the effects of vibration in compact assemblies. Class B insulation, along with the listed thermal path to the frame and the D-type winding inductance values, supports operation with common microstepping drives.
