电动汽车用驱动电机与传动系统的匹配

he performance of the drive system of EV depends largely on the driving motor. In order to meet the requirements of the various performance index of electric vehicle to improve its overall performance, choosing appropriate parameters is very important to the driving motor. It is necessary to connect a transmission or a main reducer assembly to decrease the load of the motor and the battery source between the motor and wheels because of the complicated working conditions and the large resistance change faced while the vehicle is running. so the calculation of transmission ratio is another key point . The article choosed appropriate parameters for the driving motor and designed the transmission ratio to match the parameters between the Driving Motor and the Transmission System by analysis and calculation. Meanwhile,it can help to improve the overall dynamic performance of the electric vehicle.
