Electric motor comprising a power electronics-carrying circuit board and a cooling plate

Abstract

An electric motor includes a stator having a plurality of bar-shaped field conductors. A cooling plate is arranged such that the field conductors are mechanically operatively connected to the cooling plate via current conductors that are electrically connected to the field conductors. The cooling plate is segmented into at least two sub-segments, which are electrically insulated from one another and annular or designed in a form of annular sectors. A separating surface between the sub-segments represents less than 20% of a cooling surface. A printed circuit board structure having one or more printed circuit boards, with at least one of the printed circuit boards being arranged on the cooling plate. The printed circuit boards are electrically contacted to the sub-segments of the cooling plate in order to supply power. A plurality of power electronics components controls the field conductors and is arranged on the printed circuit board structure.
