Owing to the progress of computers and numerical techniques, it has become possible to analyze the characteristics of rotating machines considering the harmonics, skin effect and magnetic non-linearity of the materials using the electromagnetic field analysis. This paper shows the latest developments of the characteristics analysis of rotating machines using the finite element method, for example, the loss analysis considering the carrier harmonics, direct calculation of eddy currents in the laminated cores, automatic finite element mesh generation and optimization using the adaptive meshing techniques. It can be said that the electromagnetic field analysis using the finite element method become indispensable for the design and optimization of the rotating machines.
