摘要
<div class="section abstract"><div class="htmlview paragraph">The electromagnetic compatibility problem of the permanent magnet synchronous motor (PMSM) has become increasingly prominent with its continuous development to high power and high torque. To solve this problem, this paper adopts a method based on the establishment of body structure and windings of the PMSM to analyze its electromagnetic radiation (EMR). The radiation stimulus source is acquired by establishing the control model of the PMSM drive system under different driving conditions in Simulink and Carsim. The EMR model of the whole vehicle is established in FEKO by creating winding models and importing three-dimensional (3D) mesh models of the vehicle body and PMSM. The field circuit co-simulation and transmission line method are used in this paper. Finally, we can obtain the electric field radiation strength at different detection points under different driving conditions. The simulation results correspond with the EMR theory and electromagnetic shielding theory. It plays a leading role in the EMR analysis of the PMSM drive system in an electric vehicle.</div></div>
