Abstract
The invention concerns a fluid-cooled electrical machine with a housing in which are arranged a stator and a rotor with stator and/or rotor coils, wherein the electrical machine is coupled heat-conductively with a cooling device arranged on its periphery and connected with an electronic power control. The electronic power control is divided into several modules, each of which are electrically connected with at least one of the stator and/or rotor coils, wherein the modules are arranged distributed on the periphery of the electrical machine and coupled heat-conductively with the cooling device.
Claims5
A fluid-cooled electrical machine with
- 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), characterised in that
- 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), in which opening protrude cooling elements (40) arranged on one of the modules (36).
Fluid-cooled electrical machine according to any of the preceding claims, characterised in that
- in the housing (10) are arranged substantially radially oriented lines (38) which connect the stator and/or rotor coils (22, 24) with the respective modules (36) of the electronic power control.
Fluid-cooled electrical machine according to any of the preceding claims, characterised in that
- in or on the housing (10) are arranged lines (50) oriented substantially along the periphery and connecting together the respective modules (36) of the electronic power control.
