Abstract

This paper presents the analysis of a permanent magnet induction machine (PMIM) with the help of the finite element method (FEM). A PMIM consists of two rotors, one with permanent magnets freely rotating in the air gap and one cage rotor. This arrangement allows to built a direct drive wind power generator with characteristics of an induction machine. To calculate this type of machine transient calculations are necessary. Due to computation time a 2-D model was chosen. Further on the moving mesh and eddy current method was used. As the wind power generator is connected directly to the grid, a circuit model which is coupled with the FEM model is included. The aim of this work was so far not to optimize the machine but to develop a tool to calculate it. First results show a good compliance with measured results
