1High quality gear-The gear is ground after heat treatment, which has the advantages of long wear resistance, long life, low noise, high accuracy, high efficiency, stable performance, corrosion resistance and easy installation. 2Metal material-The motor is made of all-metal material, making it more wear-resistant and rust-free. It is durable and the motor box is also self-developed. 3Pure copper coil-The copper wire has super-conductivity, which makes the motor has steady and strong power output, the three-layer high-density molecular paint dripping paint coating, effectively isolates dust, high temperature resistance, life is 10 tim 4Professional and practical design with beautiful appearance, easy to carry and use. 5The motor has high torsion, and the starting current of the high power motor is relatively large.
