2D Reluctance Model of an Eddy Current Brake with a Magneto Isotropic Material Structure

This work shows the model of an eddy current brake with an magneto isotropic material structure. For the modelling of the magneto isotropic material structure made of steel posts, a reluctance network is recommended, since a full FEM model would require too much computation time for optimization purposes. However, in order to map details like the skin effect in the pins, in the reluctance model some details are modelled with the help of fem and thus the required reluctances are determined. The torque calculations of the model is possible with a deviation of less than 10 % compared to an experiment.
