Product Description:

The P22NRXA-LDS-NS-02 is a motor built by Pacific Scientific within the POWERMAX II P Motors series. It converts commanded drive pulses into discrete shaft movement for positioning tasks in automated machinery. The unit belongs to the NEMA 23 frame class, carries two electromagnetic phases, and advances through 200 separate increments per revolution, enabling repeatable open-loop motion without onboard feedback devices. Because motion is produced in fixed steps, it is well suited to indexers, feeders, and other axes that need predictable incremental travel from a pulse train.

In electrical terms, the winding set is identified as type A and arranged in series, which establishes a rated phase current of 3.3 A when the coils are energized by the drive. The series connection presents a resistance of 0.85 Ω and a winding inductance of 3.3 mH; together, these values influence current rise and the rate at which torque builds during step transitions. Each command pulse displaces the rotor by 1.8 degrees, so 200 pulses complete one revolution with a step accuracy of ±1.5%. The motor can operate in ambient temperatures from -20 °C to +40 °C, and its insulation system supports 100 MΩ resistance as well as a 340 Vdc dielectric rating to help prevent leakage and breakdown.

A two-stack rotor in standard construction produces a holding torque of 1.39 Nm, while the inherent detent torque is limited to 0.049 Nm to help preserve smooth microstepping. The laminated frame measures 57.15 mm across the mounting face and follows NEMA mounting practice, and a double-ended shaft allows accessory coupling on either side. Windings are insulated to Class B, 130 °C, supporting continuous service under rated temperature rise. Regular lead wires terminate at a receptacle for connection to common machine harnesses, and the absence of an internal encoder keeps the assembly compact while position is established by the drive's pulse sequence.
