Definitions
- the invention relates to an electrical machine, consisting of a stator, a rotating shaft, with a rigidly attached rotor and a housing in which the stator is fastened, and the housing has a bearing plate on both sides with a bearing via which the shaft is mounted and optionally the housing and / or the shaft is liquid-cooled.
- Cooler flows.
- the circuit cooling can be specified depending on the speed or independent of the speed.
- the object of the invention is to provide an electrical machine of the type mentioned at the outset, which has a cooling system which permits an economically optimal design of the machine.
- the electrical machine according to the invention is characterized in that at least one cooling tube for a cooling liquid is arranged in the interior of the housing near the winding provided in the stator and / or in the area of the bearings.
- the arrangement of the cooling tube in the area of the bearings is advantageously a real alternative to shaft cooling.
- the arrangement of the cooling tube in the region of the end faces of the winding heads of the stator winding is an alternative to cooling the surface of the housing.
- the cooling tube has ribs on its surface.
- the cooling tube is arranged parallel and / or concentrically to the end faces of the winding heads of the winding provided in the stator.
- the end faces or the area of the winding heads themselves are ideally suited to dissipating the heat loss from the active parts of the machine.
- the cooling tube is arranged parallel and / or concentrically to the bearing of the shaft. This area is also well suited to dissipating the heat loss from the shaft. In addition, it is desirable not to overheat the storage area.
- the cooling tube is connected to the housing surface cooling and / or to the shaft cooling. Since the cooling of the interior of the machine by means of the cooling tube can be used as a real alternative to a possible shaft cooling but also to a liquid housing surface cooling, the cooling liquid of the shaft cooling or the surface cooling can advantageously also be used for the cooling tube.
- the connections of the cooling pipe can be integrated directly into the corresponding cooling circuit.
- Fig. 1 shows a section through an electrical, rotating machine and Fig. 2 shows a cooling tube.
- the electrical, rotating machine is a three-phase asynchronous machine, in this embodiment with a slip ring rotor.
- a machine can be used, for example, as a generator in windmills or wind power plants.
- the machine consists of a stator 1 and a rotor 2.
- the stator 1 has a winding 3 and is surrounded by a machine housing 4, the bearing plates 5 with the bearings 6 laterally delimiting the machine.
- the machine housing 4 is double-walled for liquid surface cooling.
- the shaft 7 for the rotor 2 is mounted in the bearings 6.
- the shaft 7 is passed through the end shield 5 on one side of the machine and the slip rings 8 are arranged at the extended shaft end.
- the slip rings 8 are provided with a cover 9 fastened to the end shield 5, the terminal box also being able to be provided on the cover 9.
- the rotor 2 consists of layered rotor plates 10, which are arranged on the shaft 7. This rotor 2 has a slip ring rotor winding 11 which is guided to the slip rings 8 via bores 12 in the shaft 7.
- the machine housing 4 is double-walled for liquid cooling. With this jacket cooling, the cooling liquid is supplied via the connections 13.
- a cooling tube 14 is provided in the interior of the machine, which is arranged in the area of the winding 3 of the stator 1, in particular parallel to the end faces of the winding heads of the winding 3.
- This cooling tube 14 can be connected to the jacket cooling via connections 15 when jacket cooling is carried out.
- the cooling pipe 16 can be connected to the jacket cooling via the connections 17 or separate connections could be provided.
- the cooling tube 14 or 16 is provided on its surface with ribs to enlarge the surface.
- Suitable materials for the cooling pipe 14 or 16 are, for example, aluminum or stainless steel materials. The material decision of the cooling tube 14 or 16 is certainly dependent on the coolant used.
