Product Description:

The P21NRXD-LNN-NS-00 is a hybrid stepper motor produced by Pacific Scientific and supplied within the POWERMAX II P Motors series. In positioning and indexing stations, this motor receives step-and-direction pulses from a drive and turns them into discrete angular increments, allowing open-loop control of conveyors, pick-and-place heads, and small gantries. It is suited to compact motion tasks where repeatable indexing is needed without the complexity of a servo system.

This model fits the NEMA 23 frame envelope, so its face mounting pattern aligns with common 2.3-inch square housings. Each command advances the rotor by a 1.8-degree increment, and 200 of these increments complete one revolution, giving a full-step count of 200. Actual motion error stays within ±1.5% of the commanded angle, and that accuracy is supported by the single-stack lamination design and the D-series winding. The motor uses a Class B 130 °C insulation system, allowing the copper to reach that temperature without loss of dielectric strength. Standard construction, a regular lead-wire connection style, and receptacle termination simplify cable routing in compact control cabinets. No encoder is installed, so any required verification must be handled by the host controller.

The motor operates in ambient air from -20 °C to +40 °C and has an insulation resistance of 100 Megohms at room temperature. Its dielectric barrier is rated at 340 Vdc, supporting use with high-voltage bipolar drives. A smooth shaft with a single output end simplifies coupling to timing pulleys or flexible couplers, while the NEMA face mounting style secures the rotor centerline without additional adapters. Regular lead wires exit through the receptacle, keeping the motor body free of pigtails and reducing snag risks during installation.
