ABSTRACT:
A stator of an electric machine comprises a frame mounted on a base by means of supporting feet. A laminated core is supported in the frame with its laminations clamped together in the axial direction by support ribs located in slots in the frame. The support ribs are equally spaced around the periphery of the core said only the support ribs adjacent the maximum rigidity portions of the frame are attached thereto and made resilient. Such an arrangement of resilient links between the core and the frame tends to minimize the stator vibrations transmitted to the frame and the base. The support ribs not attached to the frame are provided for uniform compression of the core and may be rigidly secured to the surface thereof.
