2D analysis of rotational loss tester

In this study a rotational single sheet tester is simulated using a 2D finite element software Flux2D. Its main goal is to find the best geometrical structure of the device which reaches the largest homogeneity of the magnetic field in the sheet plane. This imposes the size of the sheet area in which the measurements have to be achieved. The simulations have been performed using the magnetic vector potential A formulation and have been limited to a magnetostatic case. The results point out that the square shaped specimen is the best one. The influence of the yokes width is also shown and discussed.
