P22NRXB-LDN-PJ-00 by Pacific Scientific

The Pacific Scientific P22NRXB-LDN-PJ-00 motor belongs to the POWERMAX II P Motors series, delivering high-performance motion control in industrial automation. This stepper motor features 2 rotor stacks for enhanced torque density, providing a torque range of 142-201 oz-in (1.00-1.42 Nm) and a precisely machined shaft diameter of 0.2500 in (6.35 mm). Designed for applications demanding accurate positioning and repeatability, the P22NRXB-LDN-PJ-00 excels in CNC machines, robotics, and automated assembly systems.

Detailed technical specifications underscore this motor’s versatility and reliability. The P22NRXB-LDN-PJ-00 supports Agilent Technologies encoders for fine feedback integration, while its inductance is measured under 1 kHz, 1 A conditions using an impedance bridge to verify performance. The motor features flexible phase sequencing & rotation direction options and flying lead winding termination for simplified wiring. Shaft modifications include a rear extension or a flat front shaft to accommodate custom couplings. Thermal resistance is assessed unmounted in still air, ensuring the design meets cooling expectations without additional heatsinks.

This stepper motor operates reliably within a motor ambient max temperature of 40°C (still air, no heatsink) and endures winding temperatures up to 130°C. The motor’s thermal dissipation is optimized through exposed laminations, and its robust construction offers high stiffness and damping. With a standard NEMA 23 frame size and compatibility with high-performance gearheads, the P22NRXB-LDN-PJ-00 supports demanding duty cycles and harsh conditions. Encapsulated windings and precision-ground outer diameters enhance durability, minimizing maintenance downtime. Ideal for industrial use, this motor delivers precise control, extended service life, and seamless integration into advanced automation platforms.
