The invention discloses a motor control switching system of an electric vehicle, which is characterized in that a set of contactor array is additionally arranged, no current switching is controlled in a winding, a contactor is designed with an arc extinguishing device, the size of the contactor array is greatly reduced due to customized combination design, a mode switching function is added to a vehicle control unit, and by combining the integrated design of the motor, the contactor array is directly designed in the motor, so that the electromagnetic compatibility (EMC) capability is prevented from being influenced by an overlong outgoing line. The problem of high power consumption of continuous high-speed operation of the electric vehicle is solved, and the problem of safety risk of high induced voltage during high-speed operation is avoided.
本发明公开了一种电动汽车电机控制切换系统,增加了一套接触器阵列,控制在绕组无电流切换,接触器设计灭弧装置,接触器阵列定制组合设计体积会小许多,整车控制器增加模式切换的功能,结合电机一体设计,把接触器阵列直接设计在电机内部避免引出线过长影响电磁兼容EMC能力。本发明同时解决了电动汽车持续高速运行电耗高的问题,避免高速运转时感应电压高的安全风险的问题。
