• a rotor, which is arranged rotationally adjustable relative to the housing in the housing interior;
• and
• a stator, which is arranged fixed in place relative to the housing in the housing interior and comprises multiple magnetic field coils with electrically energizable stator windings, which for the electrical energization of the stator windings are or can be electrically connected to a power electronic system,
• wherein the power electronic system comprises a cooling plate for cooling the power electronic system and is formed by a power electronic module that is formed separately from the housing and can be inserted into the housing interior, wherein the cooling plate includes at least one first cooling passage extending along a circumferential direction within the cooling plate.
