The length of his lamination makes to form notch between iron core and skeleton structure, so as to make the upper bending part of slot insulating paper and/or lower bending
Portion is caught in notch, and fixed slot insulating paper avoids being formed due to during volume motor is concentrated to carry out spiral because slot insulating paper movement
The generation of phenomena such as big coil or coil sag.
Based on the above technical solution, with continued reference to Fig. 6 and Fig. 7, one end of iron core 140 and/or the other end it is folded
The thickness of piece is more than the thickness of 140 other laminations of iron core.
In order to reduce the eddy-current loss of iron core 140, iron core 140 is rolled by lamination, and the thickness of lamination is common
0.20~0.3mm.Slot insulating paper is for insulated core 140 and coil, and achievees the purpose that insulation not only needs slot insulating paper,
It also needs to ensure insulation distance.In order to ensure insulation distance, under normal circumstances, notch 160 is big along the axial distance of iron core 140
In or equal to 1mm.As shown in Figure 6 and Figure 7, the axial distance of notch 160 along iron core 140 be equal to iron core 140 one end and/or
The sum of thickness and the distance between iron core 140 and skeleton structure of the lamination of the other end, therefore under normal circumstances, in order to ensure absolutely
Edge distance, setting form thickness of the thickness more than 140 other laminations of iron core of the short lamination of notch 160, could be provided as being more than
Or equal to 1mm, so as to ensure that notch 160 is greater than or equal to 1mm along the distance in the axle center of iron core 140.
The technical solution of the present embodiment, by the way that the thickness of one end of iron core and/or the lamination of the other end is set to be more than iron core
The thickness of other laminations makes the notch to be formed be greater than or equal to 1mm in the upward distance of iron mandrel, so as to ensure that slot insulating paper is exhausted
The insulation distance of edge iron core and coil ensures to concentrate volume motor normal operation.
The length of the groove profile main part 110 of slot insulating paper is related with the teeth portion height of skeleton structure, both ends (A ends and B
Section) it is contour with one side of the teeth portion of skeleton structure far from iron core 140, it is more than or waits in the axial distance of notch 160 along iron core 140
On the basis of 1mm (i.e. the thickness of the lamination of one end and/or other end of iron core 140 is greater than or equal to 1mm), insulation system can
To adapt to the design size of more skeleton structures.For example, when the length of insulation system is shorter, it can be with design framework structure
Teeth portion height it is low, make skeleton structure thinner, ensure groove profile main part 110 both ends (A ends and B section) and skeleton structure far from iron
The one side of core 140 is contour, while may insure that notch 160 is greater than or equal to 1mm along the axial distance of iron core 140, on the one hand,
The material that uses of skeleton structure can be saved, on the other hand, total kilometres when rolling up motor spiral due to concentrating are the height of iron core 140
The teeth portion height of degree and skeleton structure, therefore, in the case where iron core 140 is constant, since the teeth portion height of skeleton structure reduces,
Stroke during spiral can be shorter, saves the usage amount of coil, effectively reduces the concentration volume loss of electric machine.
The technical solution of the present embodiment by adjusting the teeth portion height of skeleton structure, occurs skeleton structure design size
During change, the both ends (A ends and B sections) that groove profile main part can be just made without being changed accordingly to slot insulating paper are remote with skeleton structure
It is contour from the one side of iron core, the application range of slot insulating paper is increased, reduces the style of slot insulating paper, it is exhausted to reduce making slot
The working hour of edge paper, cost.The spiral stroke for concentrating volume motor can be reduced simultaneously, save the usage amount of coil, it is effective to drop
It is low to concentrate the volume loss of electric machine.
