Abstract: As one of the three electric systems representing the core technology of new energy vehicles, the e-motor system is the key device to determine the power output of the vehicle. Whether the e-motor system matches with the vehicle directly affects the power performance, economy, ride comfort and subjective driving experience of the vehicle. Therefore, the e-motor system for the development of new energy vehicles is no less important than the power battery and vehicle control system. In this paper, combined with the technical development trend of the new energy e-motor system in recent years, the technical attributes of the new energy e-motor system as the theoretical basis, the installation space, performance, working environment and other technical requirements of the e-motor system in the development process of new energy vehicles as the starting point, analysis of e-motor system in the matching of new energy vehicles need to pay attention to the key problems and corresponding solutions.
