WHEEL HUB MOTOR AND METHOD FOR USING SAME

摘要

The present invention discloses a hub motor in which several annularly distributed magnet steels and at least two Hall elements are provided in a hub casing. The magnet steels synchronously rotate with a rotating seat; the rotating seat synchronously rotates with a crank chain wheel. The Hall elements are fixed in a position close to the magnet steels; signal outputs of the Hall elements are connected to a controller of the hub motor. The hub motor is used and installed behind a bicycle. When a rider is treading on bicycle pedals, the controller controls the hub motor to operate. When the rider stops treading on the bicycle pedals, the controller controls the hub motor to stop operating; when the rider reversely treads on the bicycle pedals, the controller controls the hub motor to stop operating. The present invention frees the user from the need to install a booster sensor between a frame and the crank chain wheel in the electric bicycle equipped with the hub motor and realizes convenience in overall installation, and it can avoid a situation wherein the booster sensor is damaged due to its exposure to an external environment.
