Abstract

The cage rotor (3) has a rotor core with a groove (6). The axial end (7,11) of the rotor core has a cast-short-circuit ring (8,110) of material (108), and a rod (9) that is arranged in the groove. The rod has a storage device (12) that is mounted in the groove by a deformable support (10). The storage device is connected with a storage unit (14) that is integral with the rotor core. The rotor core comprises a sheet that is arranged in the axial direction adjacent to a plate (15). The storage device is provided in a groove base (13) of the groove. Independent claims are included for the following: (1) a method for manufacturing rotor core; and (2) a method for manufacturing cage rotor.

Description

technical field

[0001] The invention relates to a cage rotor according to the preamble of claim 1 , an electrical machine comprising the cage rotor and a rotor composite lamination for the cage rotor. In addition, the present invention also relates to a method of manufacturing a cage rotor. Background technique

[0002] A cage rotor of this type is known from WO 2012 / 041943 A2. Measures for improving the quality of the cage rotor and of the asynchronous machine are described here in order to overcome or reduce the problems that arise here. It is described there that the cage rotor of an asynchronous machine has rods in the rotor stack, wherein the rods can be tilted in a tilted position. Advantageously, the rod can be tilted in such a way that its end can be tilted towards the axis of the cage rotor. That is to say, in the end region of the rotor stack there is a gap for the rod, wherein the rod can be bent in the direction of the gap. That is to say, the play enables be...
