The novel wheel motor for electric vehicles is designed to install inside the wheel, and therefore the power dissipation from traditional transmission mechanism and reduction gears is eliminated. One of the design objectives is to increase the driving range of the vehicle; this will be accomplished by an optimal design of the wheel motor with high torque-to-weight ratio and high efficiency. The drive will also provide the capability of electronic gears by parallel or series connections of batteries and motor windings. The armature reaction yielding a distortion of flux distribution will be considered to modify the optimal current waveform that is proportional to the back electromotive waves. The key technologies of the wheel motor in this proposal are to fabricate the toroidal electric steel stacking of the stator and the compact rotor embedded with magnets. The company in cooperation with the academy is responsible for the fabrication of prototype, plan of mass production, engineer training, installation of the wheel motor on the electric motorcycle, road test for driving range and efficiency. The final results are shared with each other and the technology transfer is processed under the law.電動機車車輪馬達螺旋疊層定子雙面嵌合轉子wheel motortoroidal electric steel stackingcompact rotorelectric vehicle
