Inductive analysis of a multiconductor system prototype

Broadband circuit models for electric machines are effective means to understand, predict, and control the phenomenon of conducted Electromagnetic Interference (EMI) from immunity/susceptibility perspective. These models should cover the capacitive and inductive coupling behavior of the component along the frequency band of interest. The circuit models when used under generic SPICE simulation softwares, are very helpful for design-related and troubleshooting activities. In this paper the inductive coupling for a winding on a laminated ferro-magnetic core prototype has been investigated and analyzed with aid of the freely available FEMM software package.
