Analytical iron loss model for the optimization of magnetic gear

Abstract : This article deals with analytical models dedicated to iron losses in yokes and pole pieces of a magnetic gear with a concentric structure. The magnetic field distribution is determined in yokes by solving both Poisson's and Laplace's equations, whereas for pole pieces the magnetic field is computed by coupling the previous analytical model with a reluctance network model. The iron loss can then be determined in post-processing from the magnetic field analytical computation. The iron loss model used in this article takes into account the temporal and spatial variations of flux density. Results of this global analytical model permit to analyze the temporal and spatial evolution of flux density. In recognizing that the purpose of this model is to be integrated into a set of models for the global mechatronic optimization of magnetic gears, it is essential to minimize computation time. This work is being applied in the context of high-power (multi-MW) wind turbines.
