Features: brand new and high quality Uniform wiring: The coil is made of pure copper enameled wire, which is wound with imported technology. The copper wire is evenly arranged, and it will not have problems such as excessive temperature, torque decline, and increased noise after long-term operation. High-quality bearings: The surface of the rotor is coated with epoxy resin to prevent the adsorption of burrs on the Biot surface of the rotor. The magnetic field of the motor is more stable, the operation is smoother, the noise is lower, and the service life is longer. Fully automatic welding: The circuit board is welded by a fully automatic welding machine, and the welding point has high accuracy. Compared with the traditional process, the distribution of the welding points is more uniform, firmer and more beautiful. High-quality copper material: stable chemical properties, non-magnetic, and can be recycled and reused. It is a metal material with a virtuous cycle. Mature technology: The copper profile adopts two processes of heat and cold in the production process, which has strong corrosion resistance.
