Abstract
Official abstract text for this publication.
The invention relates to a cage rotor for an asynchronous machine ( 1 ) comprising starting bars for improving the starting behavior. The invention further relates to a method for producing such a cage rotor. In order to achieve as great an efficiency as possible, the cage rotor comprises a laminated rotor core ( 2 ) having grooves ( 3 ) and operating bars ( 5; 6; 7; 8; 15 ) disposed in the grooves ( 3 ) and contacting the laminated rotor core ( 2 ) directly on the inner groove base as seen in the radial direction of the cage rotor, wherein the operating bars ( 5; 6; 7; 8; 15 ) comprise partial cladding ( 9; 10; 11 ) enclosing an outer surface of the operating bars ( 5; 6; 7; 8; 15 ) as seen in the radial direction ( 12 ) of the cage rotor, wherein the material of the operating bars ( 5; 6; 7; 8; 15 ) comprises a greater specific conductivity than the material of the partial cladding ( 9; 10; 11 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A cage rotor for an asynchronous machine, said cage rotor comprising: a laminated rotor core having grooves; and operating bars arranged in the grooves and resting directly on the laminated rotor core at an inner groove base, as seen in a radial direction of the cage rotor, wherein each of the operating bars has a partial sheathing which sheathes only an outer part of the operating bar as seen in the radial direction of the cage rotor to thereby in…
