Product Description:
Pacific Scientific’s P22NRXA-LSF-NS-02 belongs to the POWERMAX II P Motors series and is a two-phase hybrid stepper motor used for indexers, small gantries, and other open-loop positioning axes in industrial automation. It accepts step commands from a drive to generate rotary motion in fixed angular increments without the need for an internal feedback device. This operating method supports straightforward motion control in machines that rely on repeatable step positioning rather than closed-loop servo correction.
The motor fits the NEMA 23 frame outline and produces a holding torque of 1.39 Nm when the windings are energized. Each full step covers 1.8 degrees, giving 200 discrete positions per revolution, and a step accuracy of ± 1.5 % keeps cumulative position error low. Two stator phases drive a standard rotor with two stacks, while detent torque is limited to 0.05 Nm for smoother idle behavior. The A-type winding draws 6.5 A per phase through a 0.42 Ω resistance, supporting quick current rise for high pulse rates. This winding arrangement and the standard construction contribute to repeatable electrical characteristics across identical units.
The motor has a protection level of IP23, which is suitable for clean, ventilated enclosures. Continuous operation is specified from -20 °C to +40 °C, and the case may reach 95 °C at full load. Class B insulation rated for 130 °C, an insulation resistance of 100 MΩ, and a dielectric withstand of 340 Vdc safeguard the coil system. The 0.8 mH winding inductance shapes current decay during microstepping, and a flat-machined shaft supports secure coupling. The mounting style follows the NEMA interface, and power is delivered through standard lead wires that plug into a receptacle. No encoder is fitted, so the motor is intended for open-loop control.
