The winding structure further comprises an aperture-variable winding skeleton, the front end cap is connected with the rear end cap via the aperture-variable winding skeleton, the external-layer winding and the internal-layer winding are wound on the winding skeleton in positions of different apertures respectively. Compared with the prior art, the thickness of the end portions of the windings can be reduced.
Description
Technical field
The present invention relates to a kind of winding mould, especially relate to a kind of multi-layer hollow cup motor end thickness that reduces
Winding construction.
Background technology
Drag cup winding through winding mould coiling (the most hexagonal winding former but be not limited to hexagon), around
To hexagonal winding thermal crushing after system, finally strip winding being rolled into circle, the winding of formation easily occurs two
The phenomenon that end is thicker than interlude, reason is hexagonal two end leads distribution ratio intermediate layer more crypto set, pressure
Being easier to after flat occur to overlap, therefore two ends are thicker.
Fig. 1 is the winding mould of the most conventional Double Layer Winding, and in figure, 1 is drive end bearing bracket, this end cap and coil winding machine phase
Even, 2 is rear end cap, and 3 is the bobbin of 6 location rod iron compositions, and rod iron is solid with rear end cap 2 by glue
Fixed, by adjusting the relative position of rod iron, can design by the shape of coiling, in order to roll two-layer winding, point
Not coiling two-layer winding on winding mould, wherein 4 is outer layer winding, and 5 is the lead-out wire of outer layer winding, and 6 are
Internal layer winding, 7 is inner side winding leading-out wire.
Use coil winding machine winding mould is carried out coiling, winding is through thermal crushing afterwards, roll up round-formed as shown in Figure 2
Shape, the lead-out wire 5 or 7 of each layer can connect according to triangle or Y shape, finally by layer and layer around
Group (4 and 6) by being connected in parallel or in series, the winding in Fig. 2 be the number of phases be three, between each layer winding (5
Or 7) link with triangle, between layers according to being connected in parallel.
Owing to part that Single-layer Windings is the thickest all concentrates on two ends of winding, after two-layer winding rolls into circle,
The end of two-layer winding just overlaps each other, and causes end thickness to accumulate, thus exacerbate two ends of winding
Thickness, causes winding overhang inconsistent with interlude gauge.It is tired that this phenomenon can cause winding and stator to be installed
Difficulty, declines the space availability ratio between rotor it addition, this phenomenon also results in winding, then causes the motor can
The quantity of the winding conductor to place declines, and finally causes the hydraulic performance decline of motor.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide that a kind of to reduce multilamellar empty
The winding construction of heart cup motor end thickness, can reduce winding overhang gauge.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of winding construction reducing multi-layer hollow cup motor end thickness, including drive end bearing bracket, rear end cap, outer layer around
Group, outer layer winding outlet, internal layer winding and internal layer winding outlet, described outer layer winding is with outer layer winding outlet even
Connecing, described internal layer winding is connected with internal layer winding outlet, it is characterised in that described winding construction also includes hole
The bobbin of footpath change, described drive end bearing bracket is connected with rear end cap by bobbin, described outer layer winding with
Internal layer winding is rotating around on bobbin, and is positioned at different pore size.
Preferably, described bobbin is step structure.
Preferably, the step of described bobbin is located at centre position, the osculum limit of described step around internal layer around
Group, great Kou limit is around outer layer winding.
Preferably, described bobbin is progressive structure.
Preferably, the aperture of described bobbin is gradually increased along internal layer winding to outer layer winding direction.
Preferably, described bobbin is made up of 6 rod irons.
Preferably, the longitudinal section of described bobbin is regular hexagon.
Compared with prior art, the invention have the advantages that
1) using staged or the drag cup winding of gradual change type, its end thickness size is thinner than traditional method；
2) mounting process simplifying motor winding with motor stator is conducive to；
3) winding overhang is more preferable with winding mid portion gauge concordance, is conducive to promoting winding to rotor
Between space availability ratio；
4) in the case of online rule allow, thicker wire can be selected, advantageously reduce the resistance of motor, promote
The performance of motor.

Lead-out wire.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
For winding overhang set forth above this problem thick, the present invention proposes two kinds can reduce winding overhang thickness
The winding scheme of size.Fig. 3 is the winding mould using staged rod iron, between drive end bearing bracket 1 and rear end cap 2
Being designed to step in the middle of bobbin 3, the left side of step is outside winding 4, and opposite side is inner side winding
5.Through the winding rolling as shown in Figure 4, owing to the height of ectonexine winding is different, therefore can be by inside and outside
The winding overhang of layer staggers, and prevents the end size superposition of ectonexine, reduces the end thickness that winding is overall.
Fig. 5 is another method reducing end thickness, coiling bone between drive end bearing bracket 1 and rear end cap 2 in figure
Frame 3 is designed to gradual change type, uses the winding of this winding mould coiling winding area near drive end bearing bracket side less,
And the area that is more proximate to rear end cap 2 side is the biggest, see Fig. 5.Use the winding of this winding mould roll-forming, as
Fig. 6, due to end in the shape of a spiral, the winding overhang thickness after therefore rolling will not accumulate on mutually same position,
The thickness of winding overhang can be staggered mutually, reduce the thickness of end.
