Tips: How does a 500W hub motor work?
Hub motor technology is also known as electric wheel motor technology. Its biggest feature is that the power unit, transmission and braking device are integrated into the wheel hub, which greatly simplifies the mechanical part of the electric vehicle. The wheel hub motor drive system is mainly divided into two structural forms: Inner rotor type and outer rotor type. Among them, the outer rotor type adopts a low-speed outer rotor motor, the maximum speed of the motor is 1000-1500r/min, and there is no deceleration device, and the speed of the wheels is the same as that of the motor. The inner rotor type uses a high-speed inner rotor motor, equipped with a reducer with a fixed transmission ratio. In order to obtain a higher power density, the motor speed can be as high as 10000r/min. With the advent of more compact planetary gear reducers, the inner-rotor hub motor is more competitive than the low-speed outer-rotor type in terms of power density.
