Product Description:
The M21NRXC-LSS-NS-03 is a hybrid stepper motor built by Pacific Scientific for the POWERMAX II M Motors series. It translates digital pulse trains into indexed shaft rotation for positioning and light-duty feed functions in industrial automation systems such as small gantries, dispensers, and test fixtures. The unit mounts to standard NEMA hardware, allowing straightforward interchange with other 23-frame steppers and direct coupling to timing belts or lead screws without additional adapters.
The motor employs a NEMA 23 flange whose across-flats dimension is 2.25 in and whose bolt circle is 2.625 in. Overall depth is 2.06 in (52.3 mm), a size made possible by the single lamination stack and enhanced construction. Rotor and winding set C generate a fundamental step of 1.8 degrees, so one electrical revolution equals 200 mechanical steps. Holding performance when phases are off is supported by a detent torque of 9.4 oz-in (0.066 Nm). Electrical connection is through regular leadwires terminated in a receptacle, and no feedback encoder is fitted. A 1.500 in pilot diameter aligns the housing, and the NEMA mounting style simplifies attachment to indexers or compact stages.
Repeatability is held within ±1.5 % of a full step, enabling accurate incremental moves without closed-loop correction. Windings are insulated to Class B, 130 °C and show 100 MΩ resistance, while the insulation system withstands 340 Vdc test potential. Heat rejection is characterized by a thermal path of 5.5 °C/Watt, so forced airflow is advised at higher load factors. The motor operates in ambient ranges from -20 °C to +40 °C and maintains performance over this span. The motor uses a standard detent-torque rotor and enhanced construction to increase mechanical stiffness under dynamic loads.
