Research on the Relevance of Radiation Emission Between Vehicle and Driving Motor System

驱动电机系统与整车电磁发射特性的关联性研究作为当下的研究热点,对揭示整车电磁发射机理以及降低电磁发射强度有重要意义。首先论述了驱动电机系统、车速、动力电池系统对整车辐射发射的影响;其次论述了搭载不同驱动电机系统车辆以及搭载相同电机系统不同车型车辆的发射特性;最后从系统级电磁兼容性设计角度提出了驱动电机系统的电磁兼容性设计方法。

The electromagnetic emission characteristics correlation between the driving motor system and the vehicle is a hot research topic, which is of great significance to reveal the emission mechanism and to reduce the intensity of electromagnetic emission. Firstly, the influence of driving motor system, vehicle speed and power battery system on vehicle radiation emission was discussed. Secondly, the emission characteristics of vehicles with different driving motor systems and different types of vehicles with the same driving motor system were discussed. Finally, from the point of view of system-level EMC design, the method of EMC design for driving motor system is proposed.
