Abstract
The invention relates to a special embodiment of a plate which is to be able to transmit movement and compressive force as well as possess soft-magnetic properties with low losses and low reluctance. The latter requirement means, inter alia, that the plate, upon loading, will be subjected to a relatively great elastic deformation with an ensuing reduced ability to transmit movement and compressive force. By perforating the plate with a number of evenly distributed holes provided with pellets of a stiff resistant material with an axial length at least as great as the thickness of the plate, movement and compressive force may be transmitted from a compressive force-generating element via the plate to a compressive force-absorbing element without the plate being elastically deformed.
