The laminated stator body of a large turbo-generator consists of a stack of laminations (1) comprising laminated compression plates (2), which stack is clamped together by means of tie plates (3) and tension bolts (8). The end face of the compression plate is stepped in the axial and radial direction. The tie plates have either a contour which matches the outside contour of the compression plate (2) or are smooth and, in the latter case, are supported by arch pressure in the radial direction. The elaborate machining of the compression plate end face, resulting in the elimination of lamination shorts, can thus be omitted without impairing the electrical and magnetic effects of the laminated compression plate on the end field of the machine.
