ABSTRACT:
A device for securing the end connectors of an electric machine stator winding, wherein the magnetic circuit stacks thereof are clamped axially by means of elements arranged on the end surfaces of the stator core, comprises two insulating conical rings, the end connectors of the winding being arranged between the conical surfaces of the rings. The outer conical ring is connected with the clamp board and is being adapted to move axially with respect to the clamp board. The inner conical ring is retained in an axial direction by means of axially arranged rods pivotally connected with the outer conical ring by means of supports. The suports are pivotally secured in the elements axially clamping the magnetic circuit stacks by means of radially arranged rods. The proposed structure provides for dependable securing of the end connectors of the winding, such that damage of insulation and loosening are avoided during the course of operation.
