Analysis of Axial Flux Permanent Magnet Motors Used for Electric Vehicle

Currently, the electrical vehicle industry needs motors that can deliver high efficiency throughout the entire vehicle running cycle. Axial flux motors are compatible with these major developments taking place in this industry. In the first part of this paper is presented the differences between the geometry of axial flux motors and the radial-flux motors to highlight the complexity of the analysis of AFPM and their particularities. Then, in the paper are presented and analyzed different classical AFPM motor variants and emerging new variants of AFPM including transversal flux motors, bearingless AFMs and magnetically geared AFPMs pointing out their strengths and weaknesses. Also, in this paper, an electromagnetic analysis of an axial flux motor type is presented.
