Product Description:

The M22NSHB-LNN-NS-02 is manufactured by Pacific Scientific that is a renowned manufacturer of precision-driven devices. It is an efficient Stepper motor. The M22NSHB motor satisfies the high requirements of modern motion control systems because of Pacific Scientific's commitment to quality. It performs reliably in extreme circumstances.

The phase resistance and phase inductance have been measured to be 0.77 Ohms ± 10% and 4.0 mH, respectively. It has been established through measurements that the power is effectively supplied with a maximum current per phase of 3.3 Amps DC. The M22NSHB-LNN-NS-02 stepper motor has an axial force capacity of 13 lb (58 N) and a horizontal force capacity of 20 lb (89 N). The stepper motor's consistent torque output of 178 oz-in (1.33 Nm) enables precise motion control when both stages are activated. Its robust construction and extended service life make it perfect for use in automated manufacturing and other demanding contexts. Because of these technical elements, the motor is able to operate in a smooth and dependable manner. Because of its numerous technical benefits, the M22NSHB stepper motor is ideal for activities that require significant torque and accurate control.

The M22NSHB-LNN-NS-02 stepper motor also has a phase resistance range of ±10%, which makes sure that all motors have the same electrical performance. The motor's average phase inductance of 4.0 millihertz provides an additional increase to the motor's capacity to retain its stability when dealing with varying loads. This advantage is provided by the motor's capacity to. This motor performs well in conditions that require accurate positioning and consistent performance due to the cautious and dependable construction that it possesses with regard to its manufacture.
