Preferably, first projection 6 is provided with multiple, and it is uniformly arranged in the inner ring of the outer rotor iron core 1, described Second projection 7 is correspondingly arranged with first projection 6, i.e. it is uniformly arranged on the outer ring of internal rotor iron core 3.
Preferably, as shown in fig. 7, first projection 6 and second projection 7 are correspondingly arranged in the axial direction, also, two Person is in the axial direction complementary structure.That is, the size of the first projection 6 and the second projection 7 is also configured to:In same axial location Exist when place, the first projection 6 and different the second projection 7.That is, in a certain axial positions, if having on outer rotor iron core 1 One projection 6, then necessarily without the second projection 7 on internal rotor iron core 3, vice versa.So when outer rotor iron core 1 and internal rotor After the relative position in the axial direction of iron core 3 determines, can freely relatively rotate therebetween, the first projection 6 and the second projection 7 Between any interference or contact will not occur.
Preferably, second projection 7 is arranged on the outer ring of internal rotor iron core 3 near the position of upper and lower end in the axial direction, That is, including two the second projections 7 of circle, first projection 6 is presented axially between the second projection 7 of upper/lower terminal, and such as the One projection 6 is arranged on the axial middle part of outer rotor iron core 1.This structure so that two the second projections 7 of circle can be in axial side It is two-way upwards to block the first projection 6, so as to improve the axial strength of cage rotor iron core 10.
Preferably, after assembling axis of the direction relative to the rotor core that the first projection 6 and the second projection 7 extends Set in angle.For example, with reference to Fig. 4, it can be seen that the bearing of trend of the first projection 6 is to be in relative to the axis of rotor core Angle is set.Second projection 7 is arranged to extend by identical angle with the first projection 6.Then, internal rotor iron core 3 and outer rotor In the assembled state, the first projection 6 and the second projection 7 are extended iron core 1 by same angle on the whole.
Preferably, the angle be it is identical with the skewed slot amount of cage rotor, so, internal rotor iron core 3 after assembling and outer Rotor core 1 collectively forms cage rotor iron core, and keeps the skewed slot amount of cage rotor to keep constant.
The first projection 6 and the second projection 7 are set by angle so that internal rotor iron core and outer rotor iron core in assembling process It is not easy voluntarily to separate, while being also convenient for the setting of shock absorber part 4, such as injection moulding.
The species of internal rotor iron core 3 can be various, for example, die casting can be used, it is possible to use metal sheet, as long as can be full The secure fit of sufficient internal rotor iron core 3 and armature spindle 5.
Preferably, rectangular fabrication hole 8 is provided with the internal rotor iron core 3, its quantity is, for example, three, and example Such as it is evenly distributed in the periphery of endoporus 9;This kind of design structure, is conducive to the installation of internal rotor iron core 3.
The quantity of the first projection 6 and the second projection 7 can set according to actual needs, but should ensure that the two in circumferencial direction On correspondence.As long as the shape of other first projection and the second projection disclosure satisfy that the condition of inner and outer rotors secure fit i.e. Can, can select arbitrary shape.
The material selection scope of internal rotor iron core is wider, is not limited to the conventional silicon steel material of existing industry, can select All can meet the material of required rigidity and plasticity when rotor core coordinates operating with armature spindle.
Internal rotor iron core 3 is fixed as one with outer rotor iron core 1 by the first projection 6, the second projection 7.Internal rotor iron core 3 With comprising the following steps that outer rotor iron core 1 is assembled:
First, fabrication hole 8 is clamped, internal rotor iron core 3 is placed on the inner ring of outer rotor iron core 1, the second projection 7 is placed on Between adjacent first projection 6;
Then, by fabrication hole 8, rotation internal rotor iron core 3, make upper end that the first projection 6 is located on internal rotor iron core 3, Between second projection 7 of lower end.
In the utility model, the molding mode of shock absorber part 4 typically uses injection moulding, needs first to manufacture outer before injection Rotor core 1 and internal rotor iron core 3, and both are fixed, its Shooting Technique is simple, strong operability.In addition, in assembling process In, aluminium ring 2 can also be first set, then in injection shock absorber part 4.
Shock absorber part 4 is fixed between outer rotor iron core 1 and internal rotor iron core 3, and the shock absorber part 4 is together with internal rotor iron core 3 Buffering effect is played in effect, influence of the torque ripple to output loading when rotor core is operated can be reduced, so as to reduce motor Vibrations;On the other hand, shock absorber part 4 is arranged between outer rotor iron core 1 and internal rotor iron core 3, is directly connect rather than with armature spindle 5 Touch, effectively prevent radial direction deformation during motor rotation.
The material of shock absorber part 4 can consider the factors such as shock-absorbing capacity, heat resistance and thermal conductivity and be selected, such as rubber, Nylon, plastics etc.;The structure of shock absorber part 4 can change according to inner and outer rotors core structure and change, various structures.
