Product Description:
The P22NRXB-LDF-NS-00 belongs to the POWERMAX II P Motors series from Pacific Scientific. It is a hybrid stepper motor intended for positioning and speed-indexing duties within automated machinery. The unit’s NEMA mounting format allows it to fit equipment built for motors of a similar frame size, so major mechanical changes are often unnecessary.
This model uses a NEMA 23 frame with a body length of 78.7 mm, and it attaches through the standard NEMA flange used for the series. Power is delivered through regular leadwires that terminate in a receptacle, matching the regular leadwire connection style. Two rotor stacks provide higher torque density than single-stack versions, while the standard rotor and standard construction keep mass and inertia moderate. The motor uses parallel windings rated at 4.6 A per phase and an inductance of 2.1 mH, presenting the drive with the expected electrical characteristics. The insulation is rated for 340 Vdc and 100 megohms of resistance, so the motor can be used on high-voltage micro-stepping amplifiers without breakdown. Because the motor has no feedback device, it is intended for open-loop control. The double-ended shaft carries a ground flat that is 12.7 mm long for fixed-position coupling on either end.
The rotor advances by 1.8 degrees per command step, yielding 200 discrete positions in each revolution, with a step accuracy of ±1.5 percent for consistent repeatability. Continuous service is allowed from -20 °C to +40 °C, supported by insulation rated at Class B, 130 °C. A shaft diameter of 6.35 mm matches common couplers and pulleys, and the flat modification helps transmit torque while reducing the chance of slippage. The motor is suitable for use with micro-stepping or full-step drives in pick-and-place stages, index tables, and small conveying systems.
