Abstract
The present invention relates to a mounting device ( ) for reducing short-circuiting forces that are transmitted from a stator core to a stator body in a rotating electric machine comprising a stator with windings drawn through slots in the stator, wherein the stator core is composed of a number of packs ( ), each of which includes a number of metal sheets, or of a number of metal sheets, each pack ( ) or metal sheet having two identical grooves ( ) arranged for cooperation with wedge members ( ) designed to join together packs ( ) or metal sheets, and wherein the stator body comprises beams ( ), each connected to a wedge member ( ). The mounting device ( ) also comprises a connector ( ) arranged through the beam ( ) and secured in the wedge member ( ) in order to connect the beam ( ) and wedge member ( ) in such a manner as to permit sliding between the wedge member ( ) and the beam ( ) in the event of short-circuiting. The windings also consist of high-voltage cable ( ).
