Product Description:

The P21NSXC-LSS-NS-07 is a hybrid stepper motor produced by Pacific Scientific within the POWERMAX II P Motors series. Serving as a positioning element in industrial automation, the unit receives step pulses from a drive and converts them into proportional shaft motion for conveyors, small actuators, and indexing fixtures. Its NEMA-pattern face and compact housing simplify mechanical integration, while the receptacle connector supports quick electrical hookup inside machine frames or control enclosures. The hybrid stepper design is suited to repeatable incremental positioning where motion is controlled through pulse counts rather than continuous feedback.

The frame conforms to NEMA 23 dimensions, and a single stack lamination set keeps the overall length moderate. The rotor uses a standard design and supplies 0.82 N·m of holding torque, while detent torque is limited to 0.028 N·m so microstepping smoothness is preserved. During motion, the shaft can reach 3000 rpm when the C winding is driven with the appropriate current profile. Each electrical cycle advances the rotor by 1.8 degrees, yielding 200 discrete steps per revolution with a step accuracy of ±1.5%. Two phases energize the motor, and the absence of an encoder means position is determined in open-loop operation.

The electrical insulation system is rated Class B, 130 °C, giving the windings a safe thermal margin during continuous duty. Resistance between the windings and frame measures 100 Megohms, confirming dielectric integrity before startup. For hipot testing and drive selection, the motor carries an insulation voltage rating of 340 Vdc. Stable performance is maintained across an ambient range of -20 °C to +40 °C, so the unit can operate in unconditioned factory spaces. These electrical characteristics support continuous-duty operation in general industrial equipment when the motor is paired with a suitable stepper drive.
