Abstract
Various embodiments of the teachings herein include an end plate comprising: a device for receiving a bearing internally with an inner fastening circle; and fasteners for fastening the end plate to the housing of the electric machine externally with an outer fastening circle. The end plate has a geometry suitable for counteracting the deformation of the first natural frequency overcoming a flat and/or planar shape, or side, respectively, of the end plate by bending the end plate, with the same or a reduced mass and/or wall thickness of the end plate.
