Design Optimization of an Axial-Flux Reluctance Magnetic Coupling based on a Two-Dimensional Semi-Analytical Model

International audienceIn this paper, design optimization of an axial flux reluctance magnetic coupling is presented. The optimal design procedure is based on a 2-D semi-analytical model defined at the mean radius combined with a multi-objective genetic algorithm (NSGA-II). In order to take into account the end-effects in the radial direction, a correction factor is defined to improve the torque and the axial force determination. The obtained results are compared with those of 3-D nonlinear finite element simulations and experimental results. It is shown that the proposed semi-analytical model is very accurate and requires very little computing time
