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).

Abstract: The invention relates to a motor unit (5) comprising a motor (1), a heat exchanger (2) and an inverter (3) for the motor (1). In order to provide a compact, low-cost motor unit it is proposed that the heat exchanger (2) is embodied for cooling both the motor (1) and the inverter (3).

Abstract: A self-supporting housing of a laminated core of a stator in a dynamoelectric machine has a laminated core section surrounding the laminated core which is formed by axially stacked sheets and includes at least one pressure plate on its faces. The inside of the laminated core section is designed such that a laminated core having a basic shape of an octagonal cross-section can be accommodated in the laminated core section, wherein shorter sides and longer sides of the laminated core alternate in the peripheral direction; at least one connecting section in the axial extension of the laminated core section to dispose additional elements and/or devices on the housing. Contact zones are provided on the inside of the laminated core section to dispose and secure the laminated core in such a way that a gap is formed between the contact zones.
