A Method for the Modeling and Analysis of Permanent Magnet Synchronous Machines

This paper introduces a method for the modeling and analysis of a Permanent Magnet Synchronous Machine (PMSM). The model is based on two dimensional Finite Element (FE) magnetic field analysis. The numerical data of FE solutions are used for obtaining the variations of the self and the mutual inductances and the flux linkages depending on the angular position rotor. In order to have a more general approach, a salient pole like machine is chosen for the analysis. In the paper, the basic steps of the modeling and the solution of the obtained model are given. The model is obtained in terms of natural a,b,c variables and solved by numerical methods. On the contrary of the usual approach, the results of the proposed model are unbalanced and non-sinusoidal.
