Such as, in the example of Fig. 1-Fig. 5, in the circumference of rotor core 1, uniform intervals is turned up the soil and is provided with eight rotor blocks 11, the outline of each rotor block 11 is formed as fan-shaped, outwards through in the radial direction at rotor core 1 of rotor 12, each rotor 12 is formed as rectangle substantially, correspondingly, the shape being mounted to the permanent magnet 2 of this rotor 12 is rectangle, thereby simplify the structure of rotor 100.
Compared with traditional rotor, eliminate traditional screens for installing permanent magnet 2, and permanent magnet 2 is bonded in corresponding rotor 12, or multiple permanent magnet 2 is linked into an integrated entity with rotor core 1 plastic packaging.Thus avoid and limit the radical length of permanent magnet 2 on rotor core 1 due to the existence of screens, thus the performance of rotor 100 can be given full play to, the chamfering process of permanent magnet 2 can be saved simultaneously.
According to the rotor 100 for motor of the utility model embodiment, by permanent magnet 2 being bonded in rotor 12 or multiple permanent magnet 2 links into an integrated entity with rotor core 1 plastic packaging, eliminate traditional epitrochanterian screens for installing permanent magnet 2, improve the performance of rotor 100 thus, the structure of rotor 100 can be simplified simultaneously.
In an embodiment of the present utility model, as shown in Figure 3, the outer end end face of permanent magnet 2 is concordant with the outer end face of rotor block 11.
Certainly, in another embodiment of the present utility model, as shown in Figure 4, the outer end of permanent magnet 2 can be stretched out outside rotor 12.
In another embodiment of the present utility model, as shown in Figure 5, the outer end of permanent magnet 2 can also be positioned at rotor 12.
According to embodiments more of the present utility model, as Figure 1-Figure 5, contiguous block 13 is connected with between the inner of multiple rotor block 11.Such as, contiguous block 13 is formed as ring block, and the inner of multiple rotor block 11 is connected with the periphery wall of contiguous block 13.
Contiguous block 13 is provided with multiple support portions 14 of spaced apart setting in the circumferential, can have one or more support portion 14 in each rotor 12, and support portion 14 is for supporting the permanent magnet 2 installed in respective rotor groove 12.Such as, in the example of Fig. 1-Fig. 5, contiguous block 13 is provided with eight support portions 14 of spaced apart setting in the circumferential, a support portion 14 is had in each rotor 12, the periphery wall that each support portion 14 is located at contiguous block 13 extends radially outward, direction radially increases each support portion 14 length in the circumferential, can increase the contact area of permanent magnet 2 and each support portion 14 thus, thus permanent magnet 2 can be made more firmly to be mounted in rotor 12.If can have multiple support portion 14 in each rotor 12, then the shape of support portion 14 can be more flexible and changeable.
Further, as Figure 1-Figure 5, the inner of each rotor block 11 is connected with contiguous block 13 by magnetic bridge 15, and rotor 100 can be made thus to be formed with flux path in the circumferential.
According to embodiments more of the present utility model, as Figure 1-Figure 2, each rotor block 11 cuts arc structure (as shown in Figure 1) for syllogic or circular arc cuts arc structure (as shown in Figure 2).That is, each rotor block 11 in rotor core 1 can adopt syllogic to cut arc and form syllogic and cut arc structure or adopt circular arc cut arc and form circular arc and cut arc structure, thus can reduced harmonic, improves the performance of rotor 100.
Specifically, each rotor block 11 in rotor core 1 is before carrying out cutting arc, the outer peripheral center of curvature of each rotor block 11 is all positioned at the center of rotor core 1, now each outer peripheral center of curvature of rotor block 11 and the center superposition of rotor core 1.It is the outward flange of each rotor block 11 in rotor core 1 is whittled into the curve that three sections of centers of curvature do not overlap that syllogic cuts arc, and the center of curvature of above-mentioned three sections of curves has a center of departing from rotor core 1 at least.Such as, in the example of fig. 1, three sections of curves that the outward flange of each rotor block 11 is cut into are respectively the first curve 111, second curve 112 and the 3rd curve 113.Thus can reduced harmonic, improve the performance of rotor 100.
It is that the outward flange of each rotor block 11 in rotor core 1 is whittled into one section of curve that circular arc cuts arc, and the center of curvature of this curve departs from the center of rotor core 1.Such as, in the figure 2 example, the outward flange of each rotor block 11 is cut into the 4th curve 114.Thus can reduced harmonic, improve the performance of rotor 100.
According to further embodiment of the present utility model, as shown in Figure 6, rotor core 1 can also form by multiple rotor punching 10 is stacked.Further, each rotor punching 10 comprises body 101 and multiple rotor sheet 102.
Specifically, the spaced apart setting in the peripheral direction of body 101 of multiple rotor sheet 102 (such as, eight rotor sheets 102 as shown in Figure 6), is connected with magnetic bridge 103 between the rotor sheet 102 of body 101 and correspondence.Alternatively, rotor punching 10 can cut arc structure for syllogic or circular arc cuts arc structure, thus can reduced harmonic, improves the performance of rotor 100.
Installing hole is limited, outwards through in the radial direction at rotor sheet 102 of installing hole between adjacent two rotor sheets 102 of each rotor punching 10.The periphery wall of body 101 is provided with multiple protuberances 104 of spaced apart setting, and for supports permanent magnets 2, each protuberance 104 is between adjacent two magnetic bridges 103 and be positioned at corresponding installing hole.
As shown in Figure 6, above-mentioned multiple rotor punching 10 is axially stacked to rotor core 1, protuberance 104 thus on multiple rotor punching 10 is the above-mentioned support portion 14 of stacked formation in the axial direction, and the installing hole on multiple rotor punching 10 is the above-mentioned rotor 12 of stacked formation in the axial direction.Permanent magnet 2 is bonded in corresponding rotor 12, or multiple permanent magnet 2 links into an integrated entity with rotor core 1 plastic packaging.And eliminate in traditional rotor for installing the screens of permanent magnet 2, avoid and limit the radical length of permanent magnet 2 on rotor core 1 (such as due to the existence of screens, the outer end end face of the permanent magnet 2 in Fig. 6 is concordant with the outer end face of rotor sheet 102), can give full play to the performance of rotor 100 thus, the structure that simultaneously can simplify rotor 100 also can save the chamfering process of permanent magnet 2.
According to the motor of the utility model second aspect embodiment, comprise the rotor 100 for motor according to above-mentioned first aspect embodiment.
According to the motor of the utility model embodiment, by being provided with above-mentioned rotor 100, the performance of motor can be improved thus.
