Abstract
The invention relates to an electric motor, in particular an electronically commutated electric motor. The electric motor has a stator, a rotor and a housing, which accommodates at least the stator and the rotor in a cavity. The electric motor also has a power output stage, which is connected to the stator and is designed to energize the stator in order to induce a rotating magnetic field. The power output stage has at least one power semiconductor with a thermal contact area, wherein the thermal contact area is thermally conductively connected to the housing, with the result that heat generated in the power semiconductor can be dissipated to the housing. According to the invention, the housing has a housing cup, which at least partially surrounds the cavity and is preferably thermally conductive and which has a cup wall, wherein the cup wall has a mating contact area corresponding to the thermal contact area.
