Patent ID: 7049716

Claim:
A fluid-cooled electrical machine comprising: a housing ( 10 ) in which are arranged a stator ( 12 ) and a rotor ( 16 ) with stator and/or rotor coils ( 22 , 24 ), wherein the electrical machine is coupled heat-conductively with a cooling device ( 30 ) arranged on its periphery and connected with an electronic power control, wherein the electronic power control is divided into several modules ( 36 ) each of which are electrically connected with at least one of the stator and/or rotor coils ( 22 , 24 ), wherein the modules ( 36 ) are arranged distributed on the periphery of the electrical machine and arranged lying radially on the outside or inside of the cooling device ( 30 ) and coupled heat-conductively thereto, wherein through the cooling device ( 30 ) run fluid channels ( 32 ), and wherein the cooling device ( 30 ) has on its outer or inner wall at least one opening ( 34 ) for at least one of the fluid channels ( 32 ), and cooling elements ( 40 ) arranged on one of the modules ( 36 ) protrude through the opening ( 34 ) and into the fluid channels ( 36 ).
