Claim Text:
1. An electric motor ( 1 ), having a stator ( 7 ), a rotor ( 5 ), and a housing ( 14 , 16 ) which accommodates at least the rotor ( 5 ) and the stator ( 7 ) in a hollow space, wherein the electric motor ( 1 ) has a power output stage ( 8 , 9 , 10 , 11 ) which is connected to the stator ( 7 ) and is designed to supply power to the stator ( 7 ) in order to generate a rotating magnetic field, wherein the power output stage has at least one power semiconductor ( 8 , 9 , 10 , 11 ) with a thermal contact area ( 19 , 26 ), wherein the thermal contact area ( 19 , 26 ) is connected to the housing ( 14 ) so as to conduct heat, with the result that heat which is generated in the power semiconductor ( 8 , 9 , 10 , 11 ) can be dissipated to the housing ( 14 ), characterized in that the housing ( 14 , 16 ) has a housing cover ( 16 ), and a thermally conductive housing cup ( 14 ) coupled to the housing cover ( 16 ), the housing cup ( 14 ) at least partially surrounds the hollow space, wherein a motor shaft ( 18 ) extends out of the housing cup ( 14 ) only at an end of the housing ( 14 , 16 ) opposite the housing cover ( 16 ), wherein the housing cup ( 14 ) has a cup wall which has a mating contact area ( 21 , 28 ) which corresponds to the thermal contact area ( 19 , 26 ), wherein the housing cup ( 14 ) further has a guide element ( 23 , 32 ) in a region of the mating contact area ( 21 , 28 ), wherein the guide element ( 23 , 32 ) guides the power semiconductor ( 8 , 9 , 10 , 11 ) when the power semiconductor ( 8 , 9 , 10 , 11 ) is joined to the housing cup ( 14 ), wherein the guide element ( 23 , 32 ) establishes operative contact between the thermal contact area ( 19 , 26 ) and the mating contact area ( 21 , 28 ), wherein the hollow space is a first hollow space, wherein the guide element ( 23 , 32 ) includes a guide element wall that defines at least one second hollow space to receive the at least one power semiconductor ( 8 , 9 , 10 , 11 ), and wherein the guide element wall includes a hook or rail.
