PCT No. PCT/EP93/01429 Sec. 371 Date Sep. 2, 1994 Sec. 102(e) Date Sep. 2, 1994 PCT Filed Jun. 5, 1993 PCT Pub. No. WO94/01918 PCT Pub. Date Jan. 20, 1994.For a squirrel-cage rotor of an electric machine, having a cage that passes through the stack axially and is made of electrically well-conductive short-circuit rods that are connected by short-circuit rings at the ends projecting from the stack, oscillation problems that result during operation with frequency converters are intended to be solved. In addition, higher natural torsion frequencies are intended to be achieved on the rotor, that is, the construction is to be made less sensitive by simple modifications to the squirrel cage in order to prevent the resonance effects. This object is attained in that respectively two, three or more short-circuit rods are guided together to rod assemblies at their ends, and these are connected to the short-circuit rings with material-to-material bonding. |
