Product Description:
The P21NSXC-LSS-NS-03 is a two-phase hybrid stepper motor built by Pacific Scientific within the POWERMAX II P Motors series. Designed for NEMA-compatible mounting, the unit translates digital pulse trains from indexers or microstepping drives into precise shaft movement for positioning tables, small actuators, and metering pumps in industrial automation. Its standard layout houses the rotor and stator in a NEMA 23 frame, while a receptacle connector provides quick electrical termination without loose flying leads. Because the model contains only motor windings and no feedback devices, it is suitable for applications where open-loop accuracy is acceptable and simplicity is preferred over encoder data.
With a static holding torque of 0.82 Nm, the motor can keep small loads stationary whenever the rated phase current of 3.5 A is applied. Motion is generated in 1.8-degree increments, delivering 200 discrete step positions, while inherent accuracy remains within ±1.5 percent of the commanded angle. The 2.3 mH phase inductance affects current rise time and microstepping smoothness, while the 1.06 Ω winding resistance limits copper losses. A detent torque of 0.03 Nm provides passive indexing when the coils are unpowered. The single-stack rotor design also reduces the motor’s axial length for installation in compact machines.
The windings use Class B insulation rated for 130 °C, allowing hot-spot temperatures above the ambient operating range of -20 °C to +40 °C. External surfaces may reach 95 °C during heavy-duty cycles, so guarding or touch-safe covers are recommended. An insulation voltage rating of 340 VDC and an insulation resistance of 100 MΩ provide dielectric integrity when the motor is powered by a high-voltage microstepping drive. The housing provides IP23 protection against limited dust ingress and water spray and uses a NEMA mounting style. A standard rotor and type C winding provide consistent magnetic performance in the single-stack configuration. Electrical connections are made through a receptacle, simplifying wiring and allowing the connector to remain securely attached during operation.
