Product Description:

Pacific Scientific, a well-known name in motion control systems, made the M22NSLB-LNN-NS-02, a high-performance stepper motor. This NEMA 23 frame motor is part of the M2 Enhanced Series and works reliably in situations that need precise motion control. Because it is built to last and has a unique configuration, the M22NSLB motor works well in industrial control systems that need to be accurate and long-lasting.

The phase inductance of the M22NSLB-LNN-NS-02 is 1.7 mH, and the phase resistance is 0.76 Ohms ±10%. This makes sure that the motor uses power efficiently and performs consistently. With two phases turned on, it has a holding torque of 179 oz-in (1.26 Nm), showing that it can handle high loads. The motor has a rated current of 3.3 amps DC per phase and thermal resistance of 1.7 °C/watt that enable it to dissipate heat fast when in operation for an extended period of time. The type B winding and series link with four flying leads allow for a variety of wiring configurations. The motor features a smooth shaft and a standard single-shaft construction. There is no rear shaft extension, making installation simpler. It also lacks a feedback encoder that makes it ideal for open-loop control systems that prefer to keep things simple and inexpensive.

Its rated current of 3.3 Amps DC per phase and heat resistance of 1.7 °C/Watt show that it can keep working properly even when it's being used all the time. Because of these features, the motor is a reliable choice for tasks that need accurate motion control and consistent performance. Pacific Scientific's M22NSLB-LNN-NS-02 motor exemplifies its commitment to offering high-quality motion control solutions for industrial automation.
