Features: 1. It is made of high-accuracy one-time forming rotor high-quality materials with high conductivity, wear resistance and long life. 2. High-quality carbon brushes have good commutation performance, long service life, good electrical and thermal conductivity and good lubrication performance. 3. High-strength magnetic tile has long service life, strong power and greater torsion. It adopts fully enclosed structure to prevent dust from entering the motor. It has simple structure, convenient maintenance and small volume, which can effectively reduce weight, save space and be reliable. 4. The gearbox is made of high-quality metal gears, which has good impact resistance and durability to reduce noise, thus delaying the service life of the gearbox. 5.
