Abstract: A turbogenerator (10) has a rotor (11) having a cylindrical rotor body (13), which at each of the two ends merges into a shaft end (14), and in a middle section has the electromagnetically active region (23) of the rotor (11), in which the rotor (11) is assembled from a plurality of rotor parts which are interconnected and arranged in series on the rotor axis (19). With such a rotor, lower losses and temperatures in the end region of the rotor, and overall a higher limit rating or a broadened output range, become possible as a result of the fact that the rotor body (13) in the active region (23) is formed of an easily magnetizable material, especially a first steel, and in that the end sections of the rotor body (13) which are located outside the active region (23) and the shaft ends (14) are formed of a material with reduced magnetizability or of a non-magnetic material, especially a second steel.

Abstract: A rotor (10) for a generator, especially for a turbogenerator, is assembled from a plurality of separate rotor elements (11, 12) which are arranged one behind the other in the rotor axis (18), wherein the rotor elements (11, 12) abut on connecting faces and are welded to one another, forming circular weld seams (17) which concentrically encompass in each case an annular central gap (37) with a predetermined gap width. In order to achieve a maximum magnetically active volume with mechanical stresses which are as low as possible, on the outer circumference of the gap (37) the gap merges into a widening cavity (38) which is adjacent to the weld seam (17).

Abstract: A method for manufacturing a rotor by welding a plurality of elements together is described. The elements have a body with cavities and surfaces to be welded to surfaces of adjacent elements. According to the method, the elements are vertically stacked one above the other to form a pile with facing surfaces to be welded together defining slots. The cavities of adjacent elements define bores that extend within the pile. Then, adjacent elements are welded together within the slots. The bore is purged with an inert gas or mixture during welding. The slots are welded at an upper part of the bore before the slots at a lower part of the bore, and a slot at the upper part of the bore is welded last.

Abstract: A rotor for a generator, in particular a high-power turbogenerator, has slots, which run axially in a rotor body and have conductor bars inserted in them, which are supported radially in the slots by means of wedges and are in each case electrically connected to one another at the ends of the rotor body in a rotor end winding. The rotor end windings are each covered by a rotor cap which is pushed over the end of the rotor body, and an electrically insulating covering channel is arranged in each of the slots between the uppermost conductor bar and the wedge and is connected outside the rotor body to a cap insulation, which is arranged between the rotor end winding and the rotor cap. The covering channels are formed with axially stepped ends at the ends of the rotor body. The cap insulation includes a ring or a plurality of cap insulation segments, which are formed toward the rotor body such that they fit onto the axially stepped ends of the covering channels, and the rotor cap is pushed directly over the cap insulation.
