Abstract

The invention relates to a magnetic field shield for electromagnetic fields, preferably in the frequency range of 50 Hz to 200kHz, essentially comprising a composite plate (1) formed by at least three layers (1.1, 1.2, 1.3; 1.1, 1.21, 1.22, 1.31, 1.32) arranged one over the other, wherein at least one of the layers is made of electrical sheet or electrical strip. According to the invention, in order to economically create such a magnetic field shield having low weight and good shielding effect, at least one of the layers is made of steel sheet 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 connects the at least one layer (1.1) made of electrical sheet / electrical strip and the at least one layer (1.2; 1.21, 1.22) made of steel sheet to each other in a bonded manner.

Description

technical field [0001] The invention relates to a magnetic field shield for electromagnetic fields preferably in the frequency range of 50 Hz to 200 kHz, in particular 60 kHz to 200 kHz, which consists essentially of a composite sheet formed of at least three layers placed one on top of the other, wherein at least One layer consists of electrical steel sheets or strips. The invention also relates to a motor vehicle, in particular an electric motor vehicle, having such a magnetic field shield. Background technique [0002] A magnetic field shield for electromagnetic fields in the frequency range from 10 Hz to 1 kHz is known from EP 1 241 926 A2, which consists of at least two layers. One layer consists of electrical steel sheet and the other layer consists of NE metal, preferably aluminum. [0003] Furthermore, a magnetic field shield for electromagnetic fields in the frequency range from 0 Hz to 50 kHz is known from DE 10 2009 039 600 B3, which consists of at least two lay...
