This article presents an electromagnetic compatibility (EMC) aware motor design method based on the prediction of the impedances of a stator winding structure. The stator structure is divided into several two-dimensional parts, and their network para

This paper proposes an improved high-frequency equivalent model of ac machine, focusing on the accurate extraction of stator-to-frame capacitance. The behavior that the capacitance decreases in several stages throughout the observed frequency is anal
