Abstract
In a threephase generator, it is suggested, for the purpose of supporting the stator plates, to provide the latter with a decoupling ring which is held securely at the stator plates on the one hand and, on the other hand, by means of clamping in a fit of the housing parts of the threephase generator on both sides. The decoupling ring can consist of two decoupling ring portions which embrace the stator plates and, at a distance from the latter, form a common clamping place for the end shields of the housing; or a radial ring can be formed, which is securely connected along the circumference alternately with the surface of the stator plates on the one hand, and, on the other hand, with certain clamping places in the housing by means of coupling segments. The half-shells of the decoupling ring and the radial ring can be formed directly by the laminations of the stator plates by means of a corresponding shaping.
