Abstract:
A hub motor to be centrally mounted within a wheel of a wheeled vehicle to make the wheeled vehicle operate by electric power comprising:a center shaft adapted to be mounted onto a wheeled vehicle frame;a motor housing rotationally mounted on said center shaft, said motor housing having an internal chamber, said motor housing is adapted to be mounted onto a wheeled vehicle wheel and designed to rotate in unison therewith;a mounting plate fixedly mounted on said center shaft, said mounting plate being located within said internal chamber;a stator mounted on said mounting plate;a drive shaft rotationally mounted on said mounting plate;a rotor rotationally mounted relative to said stator, said rotor being located within said internal chamber, said rotor being connected to said drive shaft and is to cause rotation of said drive shaft upon rotation of said rotor, said drive shaft being connected to said motor housing, whereby supplying of electrical energy to said stator causes rotation of said rotor and rotation of said motor housing which will rotate a wheeled vehicle wheel on which it is mounted; andsaid drive shaft being axially biased in order to diminish noise and insure smooth operation of the rotation of said drive shaft.
