Product Description:

The M22NRXC-LNF-NS-00 belongs to the POWERMAX II M Motors series produced by Pacific Scientific. It is a NEMA 23 frame hybrid step motor intended for open-loop positioning and speed control in industrial automation cells where repeatable incremental motion is required. As an enhanced construction unit with a single flat-machined shaft and standard electrical connections, the motor is supplied without feedback devices and relies on its 200-step-per-revolution sequence to index loads accurately within its operating window.

Electrical performance centers on a holding torque of 1.68 N·m, which secures the load whenever drive current is applied. Each full step advances by 1.8 degrees, and the manufacturer lists a step accuracy of ±1.5%, giving predictable motion for fixtures and gantries. Dynamic response is influenced by the rotor inertia of 0.0000252 kg·m², and this low inertia supports fast start-stop cycles while limiting overshoot. Class B insulation supports winding temperatures up to 130 °C, and the insulation system provides an insulation resistance of 100 Megohms with a dielectric withstand capability of 340 Vdc. Two internal stacks form the C-type winding arrangement and work with the lead set to keep coil temperature rise within the 4.5 °C/W thermal path. Continuous duty is allowed at ambient temperatures from −20 °C to +40 °C.

Mechanical limits include an axial shaft capability of 58 N and a radial side load of 89 N, which helps with coupling and belt-tension selection. The laminated stator package measures 78.7 mm in length, 57.15 mm in width, and the motor weighs 1.13 kg, so it fits compactly on standard NEMA mounts. Thermal resistance is 4.5 °C/W, allowing reliable service when airflow around the housing is modest. The motor uses a standard rotor and a flat-shaft modification, and it is supplied without a feedback device.
