Abstract (en)
[origin: WO2020200722A1] The invention relates to an end shield for motors, in particular electric rotating machines such as electric motors and/or generators, having improved stiffness. For the first time, an end shield for an electric rotating machine is presented that has a geometry suitable for counteracting distortions of the first natural frequency. In particular, an end shield geometry is presented in which the inner fastening ring and the outer fastening ring are eccentric relative to one another.
