magnetic field shield for electromagnetic fields and vehicle fitted with an integrated magnetic field shield

摘要

patent summary: "magnetic field shield for electromagnetic fields and vehicle fitted with an integrated magnetic field shield". The present invention relates to a magnetic field shield for electromagnetic fields, preferably in the frequency range 50 Hz to 200 Hz, comprising essentially a composite sheet (1) formed of at least three layers (1.1, 1.2, 1.3; 1.1, 1.21, 1.22, 1.31, 1.32) arranged on top of each other, wherein at least one of the layers is made of electric steel sheet or electric steel strip. In order to provide low cost magnetic field shielding with low weight and good shielding effect, it is proposed that at least one of the layers be made of sheet steel and at least one of the layers is made of plastic and / or elastomer, wherein the at least one layer (1.3; 1.31, 1.32) made of plastic and / or elastomer is integrally bonded with at least one layer (1.1) made of electric steel sheet / electric steel strip and at least least one layer (1.2; 1.21, 1.22) made of sheet steel.
