Product Description:
The P22NSXA-LSS-SS-04 stepper motor is manufactured by Pacific Scientific for the POWERMAX II P Motors series. It follows the NEMA mounting style, uses a receptacle connector for cabling, and is assembled with standard construction features and a standard rotor. The motor operates with two electrical phases, turning incoming step commands into controlled angular displacement for indexing tables, syringe pumps, or small gantry axes. A Class B, 130 °C insulation system and a 340 VDC insulation voltage rating support integration with common microstepping drives in industrial automation.
The P22NSXA uses a NEMA 23 frame that fits directly onto compact gearboxes or brackets without adapters. Under full energization, it develops a holding torque of 1.39 N·m, allowing static load support when the windings are DC-excited. Each phase is rated for 6.5 A in a bipolar or parallel connection, which establishes the drive current limit for full-step or high-resolution microstep modes. The copper windings have a phase resistance of 0.42 Ω, so the drive must supply adequate voltage to overcome this resistance at the rated current. A phase inductance of 0.8 mH governs current rise time; the low inductance permits higher step rates before torque begins to fall.
Position granularity is established by a 1.8-degree step angle, yielding 200 steps per mechanical revolution with a step accuracy of ±1.5%. The rotor has a detent torque of 0.049 N·m, producing a modest self-holding effect even when the coils are de-energized. Continuous operation is permitted from -20 °C to +40 °C, matching typical enclosure conditions on factory floors. With two stacks in the magnetic circuit and winding type A, the motor balances torque density against thermal rise for repeatable performance across a wide range of pulse rates.
