The Pacific Scientific T22NRHJ-LNN-NS-00 is a high-torque, two-phase, T Series stepper motor, recognized for its robust performance, low input power and smooth microstepping, making it an affordable alternative to servomotors. It features an NPT L or M type terminal box construction and is designed for intermittent duty applications. This motor, enclosed in a square 2.25 inches frame, can function optimally in small spaces due to its optimized magnetics. The standard sequence unit hosts a laminated, two-stack length rotor with a J type winding and four leads. The double-ended shaft configuration lacks a rear extension and it can accommodate an encoder if required. Notably, it delivers 4.1 ADC rated current per phase, with 0.49 Ohms phase resistance and 2.5mH typical phase inductance, offering high acceleration for rapid movement of loads. This motor outperforms similar three and five-phase motors and is well-suited for high-performance applications.
