In order to improve the stationarity of rotor turns, further, the center of circle of the center line of the magnetic shoe 3 of rotor, the center line of external rotor boss 21 and the second location hole 22 is located along the same line.
In the present embodiment, external rotor boss 21 comprises two boss portion at the two ends being arranged at outer rotor iron core 2, and internal rotor boss 11 is positioned at the centre of internal rotor iron core 1; The width of internal rotor boss 11 is less than or equal to the distance between adjacent two external rotor boss 21.Internal rotor iron core 1 is being installed on after in outer rotor iron core 2, by relatively rotating of internal rotor iron core 1 and outer rotor iron core 2, is making internal rotor boss 11 between two boss portion of external rotor boss 21.Also internal rotor boss 11 can be made to comprise two boss portion at the two ends being arranged at internal rotor iron core 1, and external rotor boss 21 is positioned at the centre of outer rotor iron core 2.
First location hole 12 and the second location hole 22 are combined to form the location hole that magnetizes of non-injecting glue.That is, after injecting glue, have at least one not do injecting glue process in the through hole that the first location hole 12 and the second location hole 22 are combined to form, so that magnetize in step follow-up, positioned by this hole, the through hole of above-mentioned non-injecting glue is the location hole that magnetizes.
The quantity of location hole of magnetizing is multiple and arranges relative to the axisymmetrical of rotor.As shown in Figure 3, in the present embodiment, the quantity of the through hole that the first location hole 12 and the second location hole 22 are combined to form is 4, arranges relative to the axisymmetrical of rotor.Above-mentioned 4 through holes can equal not injecting glues, as the location hole that magnetizes.When the quantity of the through hole that the first location hole 12 and the second location hole 22 are combined to form is 8 (number of pole-pairs of rotor is 8), the through hole injecting glue at interval can be chosen, remain 4 and still arrange relative to the axisymmetrical of rotor.Can also be the through hole (namely the number of pole-pairs of rotor is other) of other quantity, tire out no longer one by one at this and state.
As shown in Figure 4, the location hole that magnetizes can for unthreaded hole, and by injecting glue, the end of the location hole that makes to magnetize forms the through hole identical with the first location hole 12 and the second location hole 22 diameter.
As shown in Figure 5, in another kind of embodiment, in order to avoid injecting glue part (as rubber) elastic deformation in the process of magnetizing, preferably, location hole end of magnetizing is counter bore structure.In the process of magnetizing, the reference column in magnet charger is located with the circumference of the location hole that magnetizes, and reaches the axial location to rotor according to the ladder face structure of counter bore structure.
The embodiment of the present invention additionally provides a kind of motor, comprises as any one rotor above-mentioned.Because above-mentioned rotor has above-mentioned technique effect, the motor with above-mentioned rotor has same technique effect, introduces no longer in detail at this.
The embodiment of the present invention additionally provides a kind of installation method as any one rotor above-mentioned, comprises step:
S1: loaded by internal rotor iron core 1 in outer rotor iron core 2, relatively rotates internal rotor iron core 1 and outer rotor iron core 2, the first location hole 12 of internal rotor boss 11 is alignd with the second location hole 22 of external rotor boss 21;
In the present embodiment, according to design requirement, processing internal rotor iron core 1 and outer rotor iron core 2; And outer rotor iron core 2 and magnetic shoe 3 are put into injection moulding magnetic shoe mould, be injected into one.Also after internal rotor iron core 1 and outer rotor iron core 2 injecting glue, again magnetic shoe 3 and outer rotor iron core 2 can be injected into one.
S2: by positioning element through the first location hole 12 and the second location hole 22; Wherein, positioning element can be die ejector pin, also can be alignment pin.By arranging positioning element, reach the effect of location internal rotor iron core 1 and outer rotor iron core 2.
S3: injecting glue; Note rubber or other padded coamings, make the integral type rotor structure of injection moulding, vibration damping.
S4: rotor enters axle and to magnetizing.
The installation method as any one rotor above-mentioned that the embodiment of the present invention provides, has the technique effect same with above-mentioned rotor, introduces no longer in detail at this.
Further, in S4, the first location hole 12 and the second location hole 22 are combined to form the location hole that magnetizes of non-injecting glue, and the location hole that magnetizes mates location mutually with magnet charger reference column.By above-mentioned setting, further increase the Position location accuracy of the process of magnetizing, improve the effect that magnetizes.
