This paper firstly illustrated the theory of the EMI of the EVmotor control system. Second-ly, proposed an EMI test method of the EV motor control system, which include conducted emission tests and near-field radiation emission tests. The conducted emission tests focus on the DC bus, three-phase power cables, the common-mode current, as well as the DC bus transient pulse emission in the main power circuit;The near-field radiation emission test focus on the near-fieldelectric and electromag-netic field around the DC bus, three-phase power cables and the PCB. From the EMI tests, we could estimate the EMI characteristics of the EVmotor control system.We could find out whether the conduct-ed current andvoltage meet the corresponding EMI standards,find out the accurate position which gener-ate the EMI signal. Thus provide a good theoretical and test basisfor the system EMC design in the next stage .
