Product Description:
Pacific Scientific produces the P22NSXA-LDN-NS-02 as part of its POWERMAX II P Motors series. This NEMA-frame stepper motor is used in industrial automation to index tooling, track conveyor movement, and position light fixtures where open-loop control is acceptable. It delivers incremental motion without an integrated feedback device and suits machinery that still needs repeatable positioning.
The motor follows the dimensional envelope of a NEMA 23 frame and has an overall body length of 78.8 mm, so it fits standard mounting brackets while leaving space for cabling through its receptacle connection. A holding torque of 1.39 Nm allows the rotor to resist static loads between steps, and the rated phase current of 6.5 A matches drives that can supply low-impedance windings of 0.42 Ω and 0.8 mH. Each full step advances the shaft by 1.8 degrees, and with 200 steps per revolution, this sets the fundamental resolution before microstepping is applied. Two laminated stacks with type A windings generate magnetic flux while keeping detent torque at 0.05 Nm, which helps limit positional error when power is removed. A double-ended smooth 6.35 mm shaft eases coupling at either end, and the NEMA face helps maintain alignment.
Mechanical load limits are 60 N axially and 90 N radially, which helps protect the bearings during belt tension or end-thrust conditions. The low rotor inertia of 0.000025 kg·m² supports rapid acceleration, while the approximately 1 kg mass of the housing helps damp vibration. Class B insulation tolerates 130 °C winding temperatures, backed by 100 MΩ insulation resistance and a 340 Vdc dielectric rating. Operation is permitted from -20 °C to +40 °C, and the standard construction with a smooth shaft and no feedback encoder keeps total step accuracy within ±1.5 %. Receptacle terminations and the NEMA mounting style simplify installation in standard machine layouts.
