Description of the drawings
In conjunction with attached drawing refering to the detailed description of detailed description below, the utility model will be more fully appreciated, it is attached Same reference numbers refer to same element in view always in figure.Wherein:
Fig. 1 be the utility model is related to motor rotor construction a kind of embodiment structural schematic diagram;
Fig. 2 be the utility model is related to motor rotor construction another embodiment structural schematic diagram.
Specific implementation mode
To help those skilled in the art that can definitely understand the theme of the requires of the utility model protection, with reference to Specific embodiment of the present utility model is described in detail in attached drawing.
The utility model is related to motor rotor construction be suitable for magneto.Magneto is to establish excitation by permanent magnet Magnetic field, to realize the device of energy converting between mechanical.It has compact-sized, small, light-weight compared with electro-magnetic motor The features such as.In general, magneto includes stator and rotor, which has the structure introduced as follows.
Fig. 1 be the utility model is related to motor rotor construction a kind of embodiment structural schematic diagram.Referring to Fig.1, The rotor structure includes the rotor core 1 for constituting rotor subject and the machine shaft 6 across rotor core 1.Rotor core 1 is wrapped Include the first iron core component 11.First iron core component 11 structure in a manner of certain laminate by multiple rotor sheets 12 or rotor punching At.Rotor sheet 12 has been shown schematically with the rotor sheet between two chain-dotted lines in Fig. 1.The rotor sheet 12 of first iron core component 11 by The core material of magnetic conduction is made, such as is made of silicon steel or magnet steel.The iron core material of the rotor sheet 12 of the first iron core component 11 is made Material is usually containing elements such as C, Si, Fe.It should be noted that in the example of the utility model, the first iron core will also be made The core material of the rotor sheet 12 of component 11 is known as being made the core material of the first iron core component 11, in example, to be different from down The core material for constituting the first iron core component 11 is also known as the first iron core by the second iron core component 21 that text will be mentioned that herein Material.
Further, the first iron core component 11 can be segmented, that is to say, that as shown in Figure 1, rotor iron The heart 1 is made of multiple first iron core components 11, and each first iron core component 11 is laminated by rotor sheet 12.In another situation Under, rotor core 1 only includes first iron core component 11, it is laminated by rotor sheet 12.The specific configuration of rotor core 1 With skilled in the art realises that conventional rotor core it is consistent, do not repeat herein.
According to the example of the utility model, in rotor core 1, the direction vertical with machine shaft 6 setting it is at least one Second iron core component 21.Example referring to Fig.1, the second iron core component 21 are arranged between the first iron core component 11.Second iron Heart component 21 is made of a rotor sheet 22 or multiple rotor sheets 22 in a manner of certain laminate.For example, second iron Heart component 21 can be made of, the quantity of certain rotor sheet 22 is without being limited thereto 4 rotor sheets 22 as indicated in the figure.It presses According to the example of the utility model, the core material and the first iron core component 11 of composition of the rotor sheet 22 of the second iron core component 21 are constituted Rotor sheet 12 core material it is different.Constitute the core material of the rotor sheet 22 of the second iron core component 21(Herein also by the material Material is known as the second core material)The magnetic conduction requirement of rotor core 1 can not only be met, and with than the first iron core component 11 The higher intensity of first core material.For example, when the first iron core component 11 is using the first conventional core material, the second iron core The core material that intensity is more than the first iron core component 11 may be used in component 21.As mentioned above, the first core material contains Have an elements such as C, Si, Fe, in this example, the second core material of the second iron core component 21 can in the first core material C, One or more composition and ratios of the elements such as Si, Fe(For example change the proportioning of C and Si)It realizes, is also not excluded for being added other The element of intensity can be enhanced.
Due to adding the second iron core component 21 in rotor core 1, and the second iron core component 21 is more than with intensity The core material of first iron core component 11 so that the overall mechanical strength of rotor core is reinforced and magnetic conduction effect is good, effectively keeps away The case where motor is broken because of high speed centrifugation stress is exempted from.
About the setting of the second iron core component 21, in the case where rotor core 1 is made of multiple first iron core components 11, Example and without limitation, can the second iron core component 21 be set between two the first iron core components 11 of arbitrary neighborhood.Certain In example, the second iron core component 21 can be also set between multiple first iron cores 11.
Rotor core 1 shown in Fig. 1 is the form of 21 interlaced arrangement of the first iron core component 11 and the second iron core component.Ability It is that the first iron core component 11 and the second iron core component 21 can be combined according to design requirement come structure that field technique personnel, which answer conceivable, At rotor core, as long as there are two types of iron core components for rotor core tool, and one of which iron core component uses high-strength iron heartwood Material.
In addition, the rotor sheet 22 for constituting the second iron core component 21 can be one or more pieces.In the rotor core 1 illustrated In, each second iron core component 21 has multiple rotor sheets 22, and has identical quantity rotor sheet 22, as illustrated in the diagram 4 rotor sheets 22.It can also be seen that the thickness for constituting the rotor sheet 22 of the second iron core component 21, which is more than, constitutes the first iron from figure The rotor sheet 12 of heart component 11.
In some examples of the utility model, the second iron core component 21 also may be arranged at the both ends conduct of rotor core 1 End plate.This arrangement can further increase the intensity of rotor core.
Second iron core component 21 can be connect by bolt part 4 or similar to the screw element of bolt with the first iron core component 11 And it is fixed.Bolt part 4 can have it is multiple, and they pass through entire rotor core 1, by nut on the end plate of rotor core 1 With bolt part 4 tighten can so that it is convenient to rotor core 1 assembly.
Fig. 2 shows the utility model is related to motor rotor construction another embodiment structural schematic diagram.Such as Fig. 2 Shown, the construction of rotor mechanism and Fig. 1's is essentially identical, in addition to end plate and the first iron core component 11 and the second iron core component Connection between 21.This will not be repeated here for identical part, and different parts can be mentioned below.As shown in Fig. 2, the second iron core structure Part 21 and general steel plate 31, which constitute a sub-assembly 5 and the sub-assembly 5 are arranged on the both ends of rotor core 1, is used as end Plate, herein, steel plate 31 can be stainless steel plates.
Second iron core component 21 passes through rivet(It is not shown)It is fastenedly connected with the first iron core component 11.In rotor core 1 On both ends, the second iron core component 21 and steel plate 31 are also to be fixed on by way of rivet on the both ends of rotor core 1.
Although giving two examples of the utility model above in association with Fig. 1 and Fig. 2, those skilled in the art should Understand, component, element etc. can carry in some cases in two examples substitutes mutually, such as also can be by Fig. 2 Such as the bolt part 4 in Fig. 1 connects and fixes the first iron core component 11 and the second iron core component 21, exemplary rotor 1 in Fig. 1 Both ends may also set up sub-assembly 5 etc..
Although being illustrated in detail in and having described specific embodiment of the utility model to illustrate the principles of the present invention, It will be appreciated that the utility model can be with embodied in other without departing from such principle.
