Abstract
<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>
