Embodiment Construction
[0076] The present invention is further illustrated below by means of examples, but the present invention is not limited thereto within the scope of examples.
[0077] The invention provides a stator assembly of a motor, which is suitable for a motor including an inner stator. Such as Figure 1-4 As shown, the stator assembly of the motor includes a stator element 10, a stator bracket and a heat exchange device. The gaseous cooling medium in this embodiment is air. In other alternative embodiments, other gases with cooling effect can also be used.
[0078] The stator element 10 includes a stator core and a stator winding, and has a first axial end 101 and a second axial end 102 along the axial direction of the stator element 10 . The stator bracket includes a first support member 20 , a second support member 30 and a fixing portion 40 , the first support member 20 is arranged between the first axial end 101 and the second axial end 102 and has an annular structure. The first...

The invention discloses a stator assembly of a motor. The stator assembly comprises a stator element, a stator bracket and a heat exchange device. The stator element is provided with a first axial endand a second axial end along the axial direction of the stator element. The stator bracket comprises a first support member which is arranged between the first axial end and the second axial end, a second support member which is arranged on at least one annular end surface of the first support member and a fixing part which is used for fixing the stator element on the stator bracket. The heat exchange device comprises a plurality of heat exchange units arranged along the circumferential direction of the stator element, and any heat exchange unit is arranged on the support surface of the second support member. The heat exchange device is arranged on the two annular end surfaces of the first support so that the operation space of the technician is larger, and the technician does not need topass through the first support member when the heat exchange device arranged at one end of the first support member is maintained, and thus the flexibility in installing the heat exchange device canbe increased and later maintenance and replacement can be further facilitated.
Description
technical field [0001] The invention relates to a stator assembly of an electric motor, in particular to a stator assembly of an electric motor including an inner stator. Background technique [0002] For offshore wind turbines, the problem that must be solved is to effectively prevent the internal components of the generator from being corroded by moisture. A feasible solution is to implement the generator as a fully enclosed type, so as to prevent the air with high salt mist and high humidity from entering the inside of the generator. In this case, if an air-cooled generator is used, the air inside the generator can be cooled by the heat exchange device, and then the cold air can be circulated to cool the generator’s heating components. An existing specific air cooling method is to guide the cold air through the generator heating components to absorb heat, pass through the heat exchange device installed downstream of the generator heating components, re-cool the heated ai...
