Single sheet tester efficiency macromagnetic analysis - art. no. 10E103

摘要

We present here a macromagnetic numerical analysis of single sheet testers, as measuring systems for grain oriented laminated Si-Fe steels. The modeling is in time domain, and hysteresis, anisotropy and nonlinearity are suitably taken into account. The curves B(H), and the specific losses, as measured by the magnetic frame, are predicted, and compared with the local "true" values. The numerical analysis allows us to extrapolate some remarks about the efficiency and the accuracy of the measuring frame versus the applied magnetic field, the induced magnetic induction, and the rating frequency.
