Here, it should be noted that the extraction location of asterism lead-out wire and the extraction location of lead-out wire depend on stator
The winding mode of winding.Specific winding mode used by the stator module of the present embodiment will be described in detail below, when this
The stator module of inventive embodiments uses following method for winding, and after the completion of final coiling, each phase asterism lead-out wire is located at stator
The secondary outer layer of winding, each coupling outlet are located at the outermost layer of stator winding.When using other winding mode, each phase asterism is drawn
Line can be located at the outermost layer of stator winding.
In some instances, as shown in Figures 2 and 3, the line end of each phase asterism lead-out wire 24 of stator winding 2 can be along fixed
The simultaneously bending predetermined angle that extends radially outwardly of sub- iron core 1, to form radially protruding part, the neutral conductor 3 and radially protruding part are distinguished
Connection.The neutral conductor 3 is facilitated to avoid the outermost wire on welding ends 23 along the radial direction of stator core 1, as a result, to avoid interference.
Wherein, when in every phase including multichannel asterism lead-out wire, the line end of multichannel asterism lead-out wire can equal edge in every phase
Stator core 1 extend radially outwardly and bending predetermined angle and be welded to connect after, then with neutral wire bonding.Facilitate as a result,
The neutral conductor 3 avoids the outermost wire on welding ends 23 along the radial direction of stator core 1, to avoid interference.
Further, radially protruding part is more than the winding outermost layer preset distance of welding ends, during preset distance is more than or equal to
Size of the property line in stator core radially.Preferably, preset distance is greater than the size in stator core radially of the neutral conductor.
Here, the neutral conductor refers in the size of stator core radially, thickness of the neutral conductor in stator core radial direction.
Further, the neutral conductor and the radially-outer surface of radially protruding part are welded and fixed.Simplify structure, facilitates welding, and
Reduce the occupied space in axial direction.
Further, each phase asterism lead-out wire 24 of stator winding extend outwardly bending angle be 60 degree -150 spend.More into
One step, the angle of the outside bending of each phase asterism lead-out wire 24 of stator winding is 90 degree.
The neutral conductor 3 is described further with reference to the accompanying drawing.
In some embodiments, as shown in figures 1 and 3, the neutral conductor 3 can be formed as arcuate line segment shape.At this point, arc
The neutral conductor 3 of line segment shape can be in substantially parallel relationship to the circumferential direction of stator core 1, to facilitate the neutral conductor 3 and between 1 circumferential direction of stator core
Every multiple asterism lead-out wires 24 connection.
Further, as shown in figure 3, the neutral conductor 3 perpendicular to its length direction cross section can for circle；The neutral conductor 3
Cross section perpendicular to its length direction may be rectangle, as shown in Figure 1.Certainly, the invention is not limited thereto, and the neutral conductor 3 hangs down
Directly in the cross section of its length direction may be the other shapes such as oblateness, polygon.
As shown in Figure 4 and Figure 5, in some embodiments, the neutral conductor 3 may include: arc connector 31 and multiple feelers 32,
Multiple feelers 32 are connected with each phase asterism lead-out wire 24 of stator winding respectively.Thus, it is possible to avoid arc connector 31 and weldering
