Product Description:

Pacific Scientific's M21NSXD motor is an excellent choice for applications requiring accurate motion control and dependable performance. The motor's small frame size of 60mm makes it suitable for a wide range of motion control tasks. The M21NSXD-LNN-NS-02 Motor complies with worldwide safety and environmental requirements thanks to its manufacturing that meets strong quality standards. The motor carries certifications such as UL, CE, RoHS, and REACH.

The compact installation is made possible by the M21NSXD-LNN-NS-02 motor's length of 52.3 mm (2.06 inches). The maximum holding torque is 1.01 Nm that allows for smooth and controlled movement. Smooth acceleration and deceleration are ensured by the inertia rating of 0.00001200 kg·m². It is easy to incorporate the motor into systems because of its modest weight of 0.68 kilograms that prevents the systems from becoming heavy. The motor’s large 30 mm bearings increase the motor's wear and tear resistance that extends its life. This motor is capable of high-speed performance for demanding activities that reach a maximum speed of up to 3,000 rpm. Its two stack length options allow for customization to meet the precise torque and dimension requirements of industrial automation applications.

The M21NSXD-LNN-NS-02 motor complies with environmental and safety directives thanks to certifications. The motor has a longer lifespan and maintains steady performance even when running continuously thanks to the large bearings. Depending on the application, the nominal holding torque ranges from 0.67 to 1.79 Nm. Precise motion control tasks are well-suited to this motor since its design maximizes performance and lifespan. Applications requiring great efficiency and longevity can rely on its structure and technical qualities. With an emphasis on efficiency and longevity, the motor consistently meets demanding operational requirements.
