Abstract: The arrangement comprises a clamping plate (1) with a projecting portion (2), an insulating ring (3) tightly embracing the end windings (4), resilient strips (5) disposed on the outer surface of the insulating ring (3) and spaced around the periphery thereof, means (6) adapted for pressing the resilient strips (5) against the insulating ring (3) in a radial direction, interposed between the projecting portion (2) of the clamping plate (1) and the resilient strips (5), and being in contact with the projecting portion (2). Disposed in clearances between the resilient strips (5) are resilient members (9) which are in contact with the projecting portion (2) and the insulating ring (3) and provided with locking elements (12) adapted to prevent the resilient members (9) from axial displacement.

Abstract: A device for collecting the liquid cooling medium of an electric machine rotor winding which comprises an external cylindrical member having an annular recess on its internal surface fastened to the rotor in communication with the cooling medium discharge from the rotor winding, and a stationary internal cylindrical member having an external surface provided with an annular projection, extending into the annular recess of the external cylindrical member, both members being arranged concentrically with a rotor shaft. The annular projection is provided with at least one internal annular cavity open on the circumference of the projection and communicating with the liquid collecting chamber.

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.

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.
