Abstract

Wedge-shaped stator locking for an electric machine such as a generator (a doubly-fed wind generator, for example) or a motor. In the improvement, there is provided a stator locking assembly in which the support of the stator against the torque directed thereto is realized by means of one or more generally wedge-shaped members. The wedge-shaped members may be wedged between the stator back beam and a support member fastened, e.g. by welding, to the machine body structure. Additionally, the one or more wedge-shaped members may be fastened to the machine body structure by suitable fastening means, such as bolts or screws, to prevent it from being pushed out of place as a result of the machine vibrations or vertical forces, for example.
