On two ends) in one end formed the first abnormity portion 12, the other end formation the second abnormity portion 13.First abnormity portion 12 and second
Special-shaped portion 13 can have correspond to each other each other form the shape of cooperation.So-called " the first abnormity portion 12 and the second abnormity portion
13 can have correspond to each other each other form the shape of cooperation " refer to the first abnormity portion 12 and the second abnormity portion 13 with energy
It is enough to coordinate (for example, engagement or engaging) shape together, that is to say, that the shape in the first abnormity portion 12 and the second abnormity portion 13
Can be fitted to each other.
In this case, when multiple magnetic pole modules 120 to be fixed to the installation surface of rotor rim 110 (for example, inner circumferential
Face or outer peripheral face) on when, multiple carrier boards 10 of multiple magnetic pole modules 120 can be by the first abnormity portion 12 and the second abnormity portion 13
Work in coordination, i.e. multiple carrier boards 10 of multiple magnetic pole modules 120 can join end to end and surround annular.Specifically, a carrier
First abnormity portion 12 of plate 10 can coordinate with the second abnormity portion 13 of a carrier board 10 in adjacent carrier board 10, and described one
Second abnormity portion 13 of individual carrier board 10 can coordinate with the first abnormity portion 12 of another carrier board 10 in adjacent carrier board 10,
So as to multiple carrier boards 10 can be mutually positioning and surrounds annular.
As shown in Figures 2 and 3, the first abnormity portion 12 and the second abnormity portion 13 can form stepped surface.For example, first is different
Shape portion 12 can form on carrier board 10 side surface and fall from power stepped, and the second abnormity portion 13 can be in the opposite side of carrier board 10
Positive step is formed on surface.Although in figs. 2 and 3, the first abnormity portion 12 and the second abnormity portion 13 have been respectively formed a platform
Rank, but can also form multiple steps.So as to multiple carrier boards 10 of multiple magnetic pole modules 120 can be different by the first of step
Abnormity portion 13 of shape portion 12 and second works in coordination (as shown in Figure 1).
Fig. 4 is show the rotor that edge according to another embodiment of the present invention intercepts perpendicular to the axial direction of rotor one
Partial sectional view；Fig. 5 is the schematic diagram of another example for showing the carrier board in Fig. 4.
As shown in Figure 4 and Figure 5, the first abnormity portion 12 and the second abnormity portion 13 can form inclined plane parallel to each other.So as to,
Multiple carrier boards 10 of multiple magnetic pole modules 120 can be mutual by forming the first abnormity portion 12 and the second abnormity portion 13 of inclined plane
Coordinate (as shown in Figure 4).
Fig. 6 is show the rotor that edge according to another embodiment of the present invention intercepts perpendicular to the axial direction of rotor one
Partial sectional view；Fig. 7 is the schematic diagram of another example for showing the carrier board in Fig. 6.
Reference picture 6 and Fig. 7, the first abnormity portion 12 can form groove portion, and the second abnormity portion 13 can be formed and the first abnormity portion
The 12 corresponding convex portion of groove portion.For example, the first abnormity portion 12 is recessed concave, the second abnormity portion 13 is and the first abnormity
The "convex" shaped of the corresponding protrusion in portion 12.Although in figs. 6 and 7, the first abnormity portion 12 only forms a groove, the second abnormity portion
13 only form a projection, but the first abnormity portion 12 can form multiple grooves, and the second abnormity portion 13 can form multiple projections.Except
The groove and projection shown in Fig. 6 and Fig. 7, the first abnormity portion 12 may also be formed as T-slot, dovetail groove, Bevel saw teeth groove, curved surface
Serrated slot etc., correspondingly, the second abnormity portion 13 be formed as with the T-slot in the first abnormity portion 12, dovetail groove, Bevel saw teeth groove,
The corresponding shape such as curved surface serrated slot.
Although showing the example of shape in the first abnormity portion 12 and the second abnormity portion 13 above by reference to Fig. 1 to Fig. 7, according to
The shape not limited to this in abnormity portion 13 of the first abnormity portion of the invention 12 and second, as long as ensure that the first abnormity portion 12 and
Two abnormity portions 13 have and correspond to each other each other form the shape of cooperation.
Exemplary embodiment of the invention, the first abnormity portion is formed by the one end in the two ends of carrier board 10
12nd, the second abnormity portion 13 is formed in the other end, because multiple carrier boards 10 of multiple magnetic pole modules 120 can be by the first abnormity portion
12 and second abnormity portion 13 work in coordination (for example, engaging, engagement), therefore can only can be by magnetic pole by simple technique for fixing
Module 120 is fixed to rotor rim 110.For example, using simple fastener (for example, bolt, screw etc.) by magnetic pole module
120 are fixed to rotor rim 110.Specifically, the first fixing hole 14 can be opened up in one end of carrier board 10, in rotor rim
The second fixing hole 111 is opened up at 110 corresponding position, fastener 130 is fixed through the first fixing hole 14 and second
Hole 111, so as to magnetic pole module 120 is fixed into rotor rim 110.Fastener 130 can be not passed through magnetic pole box 20.
It will be appreciated that when the first abnormity portion 12 and the second abnormity portion 13 as shown in Figure 4 and Figure 5 is formed, due to carrying
Body plate 10 is not supported or positioned in the one end in the second abnormity portion 13 by another carrier board 10, it is therefore preferred to by the first fixing hole 14
Be positioned close to the one end in the second abnormity portion 13, i.e. carrier board 10 is firmly fixed in the one end near the second abnormity portion 13
To rotor rim 110.Also, it is understood that, when the first abnormity portion 12 and the second abnormity portion 13 as shown in Figure 6 is formed,
Because the two ends of carrier board 10 are all supported or positioned by another carrier board 10, therefore the first fixing hole 14 can be arranged on carrier board
10 either end, i.e. carrier board 10 can be fixed firmly to rotor rim 110 in the either end of carrier board 10.
In the prior art, the two ends of carrier board 10 do not form the first abnormity portion 12 and the second abnormity portion 13, but shape
As straight surface.In this case it is necessary to set press strip in two joints of adjacent carrier board 10, then utilize
Press strip is fixed to rotor rim 110 by bolt, so as to carrier board 10 is fixed into rotor rim 110.It can be seen that, in prior art
In, due to having used press strip, cause that production cost is high, complex process.
Exemplary embodiment of the invention, by different in the two ends of carrier board 10 the first abnormity portion 12 and second of formation
Shape portion 13 so that can be cooperated by the first abnormity portion 12 and the second abnormity portion 13 between multiple carrier boards 10 (engage or
Engagement), therefore only need that carrier board 10 is fixed into rotor by by simple technique for fixing (for example, using fastener 130)
Yoke 110, so as to press strip can be omitted.
