Abstract:
1. An electric machine ( 10 ) having a rotor ( 20 ), which has an axis of rotation ( 26 ), a stator ( 16 ) including a stator iron ( 17 ) and a stator winding ( 18 ) inserted therein, which winding has conductor ends ( 228 ), which are interconnected with a rectifier device ( 139 ), a regulator ( 231 ) for regulating an excitation current, and a cooling device in the rectifier device ( 139 ), said cooling device having a first heat sink ( 53 ), which has at least one receptacle ( 66 ), on which a current rectifier ( 147 ) is received, having a second heat sink ( 117 ), wherein the second heat sink ( 117 ) has at least one receptacle ( 120 ), on which a current rectifier ( 150 ) is received, and having an interconnection unit ( 144 ), which interconnects the current rectifiers ( 147 , 150 ) to form a bridge circuit, wherein the interconnection unit ( 144 ) has a plurality of integrally formed guide stubs ( 225 ), in which conductor ends ( 228 ) of the stator winding ( 18 ) are received, characterized in that an arm ( 234 ) of the interconnection unit ( 144 ) connects one guide stub ( 225 ) integrally to another, shorter guide stub ( 225 ), wherein the shorter guide stub ( 225 ) and the arm ( 234 ) are disposed between an end shield ( 13 . 2 ) and the regulator ( 231 ) in the direction of the axis of rotation ( 26 ).
