Features: 1. Pure copper coil: The motor is made of high-precision rotor and high-quality materials, with high conductivity, high wear resistance and long life. At the same time, it adopts pure copper group, featured with small resistance, low heat generation, low loss, stable operation and sufficient power. 2. High quality carbon brush: Under the premise that other materials meet the requirements, it has good commutation performance, long service life, good electrical and thermal conductivity and good lubrication performance. The wear resistance degree of the carbon brush directly determines service life of the motor. 3. High strength magnetic tile: Long life, strong power, greater torque. Fully enclosed structure to prevent dust from entering the motor interior, simple structure, convenient maintenance. Small size, effective weight reduction, space saving, reliable use. 4. Full metal gear: The gearbox are all made of high-quality metal gears, which have good impact resistance and durability. thus extending the lifespan of the gearbox. 5. Wide Application: This motor is ideal for intelligent toy car, robot, printer, balance car, smart home appliance, camera rocker arm, and so on.
