Product Description:

The M22NRXC-LDN-NS-00 is a hybrid stepper motor produced by Pacific Scientific for the POWERMAX II M Motors series. As a NEMA-mounted motor with internal permanent magnets, it advances 1.8° per control pulse, allowing controllers to move machinery in exact 0.009 rad increments. The unit fits into open-loop or closed-loop drive systems where a compact actuator must deliver repeatable positioning. In automated pick-and-place heads, labelers, or light conveyors, it converts electrical command sequences into repeatable mechanical steps.

The motor is built on a NEMA 23 frame and measures 78.7 mm over the stack, giving it a compact envelope while still using 2 stacks in the motor body. Its construction supports a bipolar holding torque of 1.68 Nm, which suits applications that need firm static positioning between commanded moves. Position fidelity is supported by a ±1.5 % step accuracy, which is suitable for small indexing tables that rely on open-loop control. A double smooth shaft passes completely through the rotor, so couplings or encoders can be fitted on either end. Mounting follows the NEMA pattern with a 66.67 mm bolt circle, allowing it to fit existing machine layouts that accept this frame style.

Electrical insulation is rated 340 Vdc, with Class B materials that tolerate 130 °C and a minimum insulation resistance of 100 megohms, so the coils remain stable under typical drive voltages. The stator is connected through a regular lead-wire harness that terminates in a receptacle, and there is no feedback device, which keeps cabling simple. Within an ambient range of -20 °C to 40 °C, the bearings can accept 89 N of radial load and 58 N of axial load. A 6.35 mm smooth shaft transmits torque, and the motor completes one revolution in 200 full steps. The total mass is 1.13 kg, which keeps the unit manageable in compact motion assemblies.
