Abstract

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).
