3D eddy current FE analysis of electromechanical devices

Presents the use of a 3D eddy current FE procedure for the analysis and des ign of two different induction machine structures. a radial and an axial ma chine In the first ease, attention is devoted to the simulation of locke ro tor conditions and a linear 30 time harmonic eddy current FE analysis has b een employed. The obtained results have been compared to 2D analysis and ex perimental data. The axial flux machine is analyzed under fixed speed condi tions and a 30 time-stepping and velocity eddy, current problems are solved to evaluate machine performances. Different design configurations are anal yzed in order to define the best solution.
