An electrically powered vehicle, for example a bicycle, has a motor, controller and power supply contained within a wheel compartment. A cylindrical stator frame is fixed on the wheel axle, with an inner surface of the stator frame defining a space for housing the power supply and controller circuitry. A plurality of electromagnet stator segments are mounted on an outer surface of the stator frame. A cylindrical rotor frame is coupled to the axle through bearings. An inner surface of the rotor frame is coupled to the axle through bearings. An inner surface of the rotor frame supports a plurality of permanent magnets that surround the stator segments to form a radial air gap therebetween. Mounted to the outer surface of the rotor frame by appropriate supporting structure is a vehicle tire.
L'invention porte sur un véhicule à propulsion électrique, par exemple une bicyclette, dont le moteur, le régulateur, et l'alimentation sont intégrés aux roues. Un cadre cylindrique de stator est fixé au moyeu, et sa surface intérieure délimite un espace permettant de loger l'alimentation et les circuits de régulation. Les segments d'électroaimants du stator sont montés à la surface extérieure du cadre du stator et le cadre cylindrique du rotor est relié au moyeu par l'intermédiaire de roulements. La surface intérieure du cadre du rotor reçoit plusieurs aimants permanents entourant les segments d'électroaimants du stator dont ils sont séparés par un entrefer. Un pneumatique est monté sur la surface extérieure du cadre de rotor à l'aide d'une structure porteuse appropriée.
