What's Wheel Hub Motor

Wheel hub motor is the hub and drive directly into one motor, that is, the motor, transmission and braking devices are integrated into the hub, commonly known as electric wheel, there are called wheeled motor, wheel motor. Deceleration drive type generally uses high-speed inner rotor motor, with a fixed gear ratio reducer, to obtain higher power density, motor speed up to 10000rpm. Direct drive type generally use low-speed external rotor motor, the external rotor directly connected with the hub, the motor speed is generally less than 1500rpm, no deceleration mechanism, the wheel speed and motor speed consistent. Wheel hub motor is the hub and drive directly into one motor, that is, the motor, transmission and braking devices are integrated into the hub, commonly known as electric wheel, there are called wheeled motor, wheel motor. The English name is mostly "in-wheelmotor," also known as "hubmotor" and "wheelmotor." Deceleration drive type generally uses high-speed inner rotor motor, with a fixed gear ratio reducer, to obtain higher power density, motor speed up to 10000rpm. General reducer planetary gear reducer, installed between the motor and the hub. The output torque of the motor drives the hub to rotate through the deceleration torque of the planetary gear reducer. Motor size is small, light weight, torque through the reducer, the output torque acceleration performance. But difficult to achieve lubrication, gear wear faster, short life, easy to heat. Direct drive generally use low-speed external rotor motor, the external rotor directly connected with the hub, the motor speed is generally less than 1500rpm, no deceleration mechanism, the wheel speed and motor speed consistent. Because there is no deceleration mechanism, the entire drive wheel structure is more compact, smaller axial size, higher efficiency. Requires high current when large torque is needed, easily damaging battery case permanent magnets. After the current value of the load efficiency decline.
