Product Description:

The M22NRXA-LNN-NS-00 is a hybrid stepper motor built by Pacific Scientific and aligned with the POWERMAX II M Motors series. As a two-phase NEMA 23 package, it supplies incremental rotary motion for indexing tables, gantry axes, and other industrial automation tasks that call for open-loop position control. Because it operates as a hybrid stepper, the shaft advances in fixed angular increments in response to drive pulses, which suits repeatable point-to-point motion. The device combines a standard rotor with an enhanced construction type, and its regular leadwire connection keeps wiring uncomplicated where separate feedback devices are not required.

This model has a native step angle of 1.8 degrees, and with 200 increments per revolution it supports precise positioning with ±1.5% step accuracy. Holding torque ripple is limited by a detent torque of 0.12 N·m, and rapid acceleration is supported by a low rotor inertia of 0.0000252 kg·m². Two stator stacks increase torque without changing the 78.7 mm body length, and heat leaves the frame through a thermal resistance of 4.5 °C/W. The insulation system is Class B to 130 °C, offers 100 MΩ resistance, and tolerates 340 Vdc impulse voltage. A smooth 6.35 mm single shaft exits a 38.10 mm pilot and aligns with a 66.67 mm bolt circle in the NEMA mounting style. Overall width is 57.10 mm, the winding is type A, and the wiring uses a receptacle with the regular connection style and no feedback option.

Electrical insulation is rated at 340 Vdc, and ambient operation is permitted from -20 °C to +40 °C in typical cabinet environments. The shaft can carry axial loads up to 58 N and radial loads up to 89 N, allowing couplings, gears, or pulleys to be supported without auxiliary bearings in light-duty layouts. Total mass is 1.13 kg, which helps limit reflected inertia and keeps the motor manageable for compact axis assemblies. The NEMA bolt pattern, single receptacle connection, and A-type winding support consistent installation across standard motion systems. This layout keeps both mechanical mounting and electrical hookup straightforward in indexing and transfer applications.
