Product Description:

The P22NSXC-LSN-NS-02 is a hybrid stepper motor manufactured by Pacific Scientific within the POWERMAX II P Motors series. The device fits a NEMA mounting pattern and converts sequential current pulses from a drive into controlled rotor steps. In automated machinery, this motion element positions tooling, valves, or small conveyors without closed-loop feedback, giving deterministic displacement each time the drive energizes a phase. Its hybrid construction combines permanent-magnet and toothed-rotor features so the motor can produce precise incremental movement with predictable stopping points during indexing tasks.

Its basic resolution is 1.8 degrees per full step, so a complete 360-degree rotation requires 200 drive pulses. Positional tolerance stays within +/- 1.5 %, allowing repeatable indexing when the motor is coupled to lead screws or timing belts. The housing follows the NEMA 23 frame standard, providing a 2.25-inch square face that mates with common brackets and gearheads. Magnetic flux is generated in a two-layer stator because the motor contains 2 laminated stacks, and the added active length increases holding torque without enlarging the mounting footprint. To prevent thermal damage, the windings use polyester-imide insulation rated to Class B, 130°C, which supports stable operation when internal temperatures rise during repeated starts, stops, and holding periods.

Electrical integrity is supported by a minimum insulation resistance of 100 Megohms, which helps limit leakage paths between the windings and the laminated core. The insulation system withstands up to 340 Vdc before breakdown, supporting microstepping drives that apply elevated bus voltage to reduce current ripple and improve current control. Reliable performance is maintained over -20°C to +40°C ambient conditions, making the motor suitable for equipment installed in unheated warehouses or temperature-controlled process areas. A receptacle connection simplifies cabling, and the motor uses a single smooth shaft that accommodates couplings or pulleys without secondary machining. This shaft style also supports straightforward attachment in compact motion systems where simple power transmission hardware is preferred.
