Modeling of Electric Machines Using Magnetic Equivalent Circuit Method

Meshgin-Kelk Homayoun Ph.D.

Tafresh University

4.1 Introduction

The magnetic equivalent circuit (MEC) method introduces another approach for modeling electric machines. In fact, the approach can be considered as a reduced order finite element (FE) method. By taking into account approximately accurate machine geometry, stator and rotor slots effects, skewing, type of winding connections, stator and rotor leakages, and linear or nonlinear magnetic characteristics of machine coress it is a more accurate method with respect to the winding function approach (WFA). Therefore it can be helpful for design engineers and also it may be applied to find and to study more reliable ...
