Abstract:
An electric generator adapted for use with a vehicle wheel, comprising:a housing adapted to be mounted on the vehicle wheel and having a base wall and a surrounding wall that extends from a periphery of said base wall and that cooperates with said base wall to confine a receiving space, said surrounding wall being formed with inlet and outlet vent holes that are in spatial communication with said receiving space; an air impeller disposed in said receiving space and having a spindle that extends in an axial direction transverse to said base wall and that is coupled rotatably to said base wall, said air impeller being formed with a plurality of radial impeller blades such that flow of air into said receiving space through said inlet vent hole and out of said receiving space through said outlet vent hole when the vehicle wheel rotates results in rotation of said air impeller in said receiving space; a stator coil mounted securely in said receiving space; and a magnet ring disposed in said receiving space around said stator coil and coupled co-rotatably to said air impeller such that rotation of said magnet ring with said air impeller results in an induced electrical current in said stator coil.
