Product Details

Nema 52 three  phase stepper motor 

This waterproof stepper motor nema 51 is made of high temperature resistant permanent magnets and high quality cold rolled steel sheets. The product specifications range from 170mm to 282mm. It features low noise, low vibration, low heat generation, and high reliability and stability. Due to its good internal damping, it runs smoothly and has no obvious oscillation zone, which can meet the needs of different working conditions in the automation industry.

This waterproof stepper motor nema 51 adopts the latest patented stepping driver to better solve the characteristics of traditional stepping motor with low speed climb, low speed torque and low starting frequency. It has some characteristics of AC servo and its control effect is excellent.

1. Motor parts are produced and processed using precision machine tools, and the precision is strictly controlled.

2. It has been specially treated to increase the rigidity of the motor and is therefore not easily deformed.

3. The high-density design greatly enhances the dustproof, waterproof and anti-aging properties of the motor.

4. The optimized design of the punching film effectively improves the characteristics of vibration noise and torque.
