Magnetic Equivalent Circuit Modeling of Induction Motors

Limitations/capabilities of electric machine technologies and modeling approaches for electric motor design and analysis in plug-in electric vehicle applications

“…There are consistent reports that the number of elements needed for good MEC results is much less than for the FEA, computing time for MEC and analytical methods is much smaller than for FEA, and in saturation, MEC provides a better approximation than FEA. Leakage, saturation, and harmonic effects are automatically included in many MEC models by virtue of a geometry-based reluctance network [101,156,184,185]. Various authors have attempted to combine FEA and MEC to achieve even better results [159].…”

Main inductances of induction motor for diagnostically specialized mathematical models

“…In circuit models the winding distributions and the rotor air-gap geometry are usually represented by the inductances of the motor windings [1,2]. Then, a determination of inductances is the first and necessary step of modeling [3][4][5][6][7][8][9][10].…”

A Linear-Time Complex-Valued Eigenvalue Solver for Full-Wave Analysis of Large-Scale On-Chip Interconnect Structures

“…Advances in computing performance have motivated a slight change in focus of MEC modeling efforts. Specifically, original papers on the technique [1]- [5] focused mainly on the analysis of saturated machine behavior. More recently, researchers have focused on its use in the design of electric machines [6]- [9].…”

“…For example, in [10], an MEC-based design program for inductors is described in which the researchers utilize evolutionary programming techniques to select 12 geometric properties of the device. A similar technique was used for induction machine design [5], [6], and wound-rotor synchronous machines [7], [8].…”
