Product Description:
The P21NRXS-LNS-NS-03 is a two-phase hybrid stepper motor built by Pacific Scientific within the POWERMAX II P Motors series. Designed as a NEMA-compatible positioning element, the unit converts discrete pulse commands from an electronic drive into incremental rotary motion for indexing tables, small conveyors, or pick-and-place axes in industrial automation. It supplies repeatable angular steps without an integral encoder, allowing open-loop speed and position control when external feedback is not required. That arrangement suits machines that need predictable indexing behavior and straightforward integration with a compatible stepper drive.
Its frame corresponds to the NEMA 23 standard, giving the motor a 57 mm square mounting face that aligns with common brackets and couplings. A single rotor stack and two electrical phases produce the basic 1.8 degrees step angle, so exactly 200 full steps complete one shaft revolution. Positional variation is held within ± 1.5%, and the housing has an IP23 protection class that allows convection cooling while helping block fingers and moderate airborne debris. Standard construction includes a single shaft and a regular leadwire connection routed to a receptacle, which helps simplify wiring in typical NEMA-style installations.
Electrical insulation measures 100 megohms, and the winding can withstand up to 340 VDC before breakdown. A dielectric endurance rating of 500 VDC for 1 minute confirms coil-to-frame isolation during normal use. Class B materials rated to 130 °C limit internal temperature rise, and the external case is permitted to reach 95 °C under worst-case load. Continuous operation is allowed between -20 °C and +40 °C, which fits common cabinet and ambient conditions for industrial equipment. These temperature and insulation limits describe the normal operating range for the motor when it is applied within its intended duty cycle.
