The electric vehicle was a kind of machine which was powered with power supply on board of vehicle, driven with motor, was up to the standard of traffic and rule of law. Because the environmental impact was less than traditional automobile, its prospects were widely valued, but the current technology was not mature. The dynamic core of electric vehicle technology was motor.
Motor was a electromagnetic device that achieved electric energy transformed to mechanical energy. Motor’s function was transforming electric energy into mechanical energy, it could be used as a kind of power which was dragging various production in sectors of the national economy, was the most widely dynamic mechanical application. Motor technology was a quite perfect technology. This article was from different from direction of previous research, and combining the characteristics of the electric motor,under the condition of limited energy,realized the purpose which met the demand of electric vehicle.
This paper summarized the history and development of electric vehicle, classification and characteristics, developing tendency,and basic structure, transmission diagram, working principle and advantages and disadvantages of double Output shaft motor. It made the mathematical modeling, control system, and simulation of double Output shaft motor, according to the design’s requirements, designed the transmission scheme, transmission, the transmission mechanism of Planetary tumbler and differential mechanism.
Key words: electric vehicle double Output shaft motor design developing tendency
