摘要： A rotor for an electric machine includes a laminated core and a groove which extend in axial direction from a first axial end to a second axial end along a rotation axis. The groove has a groove filling having a first material with a metal element of the periodic table. The groove filling has a cast metal region, which extends with an end region at the first axial end at least partially over the laminated core. The cast metal region extends through the groove from the first axial end to the second axial end, and fills up a first part of the groove with a first material. An insert fills up a second part of the groove with a second material which has the metal element of the periodic table. The insert part and the cast metal region are connected in a bonded manner by a connection zone.

摘要： 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.

摘要： The invention relates to an electrical machine (1) comprising a rotor (4) which is rotatably mounted around a rotation axis (5) extending in the axial direction (3) in bearing devices (16, 17), a stator (7) having two axial ends, an air gap between rotor and stator, an interior chamber (10) encompassing the stator (7) and rotor (4), a sleeve (11) encompassing a first part (111) which encloses the interior chamber (10), a frame (12) having a first (123) and a second (121) longitudinal support (123), a first (122) and a second (124) cross-support, and a dividing device (2) on the frame (12). The stator (7) comprises a fastening device (15) for connection to the frame (12) and the dividing device (2) can make the interior chamber accessible from the outside in a plane parallel to the frame (12). The invention further relates to a collection, to a frame (12), to a sleeve (11), or to a service or production method of such an electrical machine (1).
