A cage rotor for an electric machine, has a laminated rotor core having a groove, a rotor end ring that is cast on to one axial end of the laminated core and has a first material and a bar situated in the groove and supported by a deformable bearing having a bearing device. A laminated rotor core for a cage rotor includes a groove and a bearing device, an electric machine with a cage rotor, a method for producing a laminated rotor core by producing a bearing device on the laminated rotor core, and a method for producing a cage rotor by supporting a bar in a groove by a deformable bearing having a bearing device.

A cage rotor for an electrical machine includes a rotor laminated core having a groove, and a short-circuiting ring having a first material and cast onto an axial end of the rotor laminated core. Arranged in the groove is a bar which has a bar end. The bar end penetrates into the first material of the short-circuiting ring and has a plurality of notches to provide the bar end with a greater flexibility.

Cage rotor and bar comprising a notch

An electric machine includes a shaft and a rotor core mounted onto the shaft and formed of a plurality of stacked laminations. The rotor core has opposite end surfaces for attachment of a plate in such a manner as to allow an axial deflection of the laminations in the area of the plate.
