As Figure 1-Figure 4, rotor 1 of the invention, including iron core 11 and multiple Compound cages 12.Set on iron core 11
It is equipped with axially extending multiple iron core slots 111 along rotor 1.Multiple Compound cages 12, multiple Compound cages 12 are fixedly arranged on
111 in each iron core slot, wherein Compound cage 12 includes the first bonding jumper 121 and the second die cast metal structure 122, the first bonding jumper
121 are arranged in iron core slot 111, pass through the formation of the second die cast metal of die casting structure 122 Compound cage 12 in iron core slot 111.
First bonding jumper 121 is first in embedded iron core slot 111, then the second die cast metal structure 122 and the first bonding jumper 121 is die cast as
One, and be fixed in iron core slot 111.The metal material of the metal material of first bonding jumper 121 and the second die cast metal structure 122
Matter is different, such as the first bonding jumper uses the metal of easy casting forming using the low metal of resistivity, the second die cast metal structure.
The rotor of the present invention uses the die casting in iron core slot to fix to be formed by the first bonding jumper and the second die cast metal
The composition metal cage bar of structure composition, the first bonding jumper can use the low metal of resistivity, and the second die cast metal structure can be with
Using the metal of easy casting forming, the manufacturing cost of rotor can be reduced while reduce the electric energy loss of rotor, carried
High motor working efficiency.
First bonding jumper 121 is not full of whole iron core slot 111, but is left between the inwall of iron core slot 111 and fill out casting
The gap of second die cast metal structure 122, second so as to molten condition is metal filled in iron core slot 111, cools and solidifies shape
First bonding jumper 121 is together fastened in iron core slot 111 into the second die cast metal structure 122, is easy to follow-up die casting to fix
Operation.Second die cast metal structure 122 is selectively filled up the gap and is fixed on what the first bonding jumper 121 together more consolidated
In iron core slot 111.
As shown in Figure 2 and Figure 4, iron core 11 can be formed by multiple rotor packs 112 along rotor axial is stacked, each rotor
There is multiple lamination slots 113 for being evenly distributed and extending along rotor axial, the lamination of multiple rotor packs 112 on lamination 112
The corresponding iron core slot 111 to be formed and extended along rotor axial that is stacked together of groove 113.At least one side patch of first bonding jumper 121
The inwall for being placed in iron core slot 111 is set up, the second die cast metal structure 122 is fixed in remaining space die casting, when can reduce die casting fixation
The amount that second metal liquid of molten condition is penetrated between rotor pack 112, rotor transverse current can be effectively reduced,
So as to reduce cross-path loss.The position for the inwall that first bonding jumper 121 is attached to iron core slot 111 is not limited in accompanying drawing
Shown, it can also be that multiple sides are attached on the inwall of iron core slot 111.Because the first bonding jumper 121 is close to iron core slot
111 inwalls, reduce the contact area of the second metal liquid and rotor pack, reduce the second metal liquid and penetrate into rotor and fold
The total amount of piece 112, so as to reduce the cross-path loss of motor, further improve electric efficiency.It should be noted that iron core 11
Structure be not limited thereto, to avoid the second metal liquid from penetrating into rotor pack, it can also use as shown in Figure 3 one
Body formula core structure.
In one embodiment, rotor 1 also includes 1 turn of short-circuited conducting sleeve 13 and rotor driven being fixedly arranged on Compound cage 12
Dynamic rotating shaft 14.Short-circuited conducting sleeve 13 can be fixed on the both ends of rotor 1 by the way of die casting or welding.
In one embodiment, the first bonding jumper 121 can be copper bar, and the second die cast metal structure 122 is cast aluminium die casting knot
Structure.However, the first bonding jumper can also use other lower metals of resistivity, the second die cast metal structure can also use molten
Other metals of low, the easy casting forming of point, the present invention are not limited thereto.
Rotor manufacturing process of the present invention is as follows：
1st, rotor pack 112 is laminated neat (integral type rotor core is without this step) using rotor laminated tooling；
2nd, the first bonding jumper 121 is embedded in by iron core slot 111 by embedded frock；
3rd, the die casting of the first bonding jumper 121 in step 2 is fixed in rotor core groove 111 by die casting frock, formed multiple
Mate bar 12, and die casting or weld out short-circuited conducting sleeve 13；
4th, rotating shaft 14 is pressed into the rotor of step 3 by rotor shaft tooling；
5th, to step 4 rotor fine turning outer circle, cage rotor is made.It should be noted that the motor rotor construction can be with
Applied to asynchronous squirrel-cage motor, but the invention is not limited in this.
As shown in figure 5, the motor 3 of the present invention, including above-mentioned rotor 1 and stator 2, rotor 1 are arranged at stator 2
In.The structure of rotor 1 has elaborated in the embodiment above, will not be repeated here.Rotor 1 is rotatable
Be arranged in stator 2, there is running clearance between stator 2 and rotor 1.Stator 2 includes stator core and stator winding,
Stator core is formed by silicon steel plate stacking, and stator winding is in stator core slot.Stator core can also be determined using integral type
Sub- iron core.
The die casting in the iron core slot of rotor of the motor of the present invention is fixed to be formed by the first bonding jumper and the second metal pressure
Cast the composition metal cage bar of structure composition, the manufacturing cost that rotor can be reduced while the electric energy damage for reducing rotor
Consumption, improve motor working efficiency.
Finally, it is to be noted that, herein, the relational terms of such as first, second, third and fourth or the like
It is used merely to make a distinction an entity or operation with another entity or operation, and not necessarily requires or imply these
Any this actual relation or order be present between entity or operation.Moreover, term " comprising ", "comprising" or its is any
Other variants are intended to including for nonexcludability, so that process, method, article or equipment including a series of elements
Not only include those key elements, but also the other element including being not expressly set out, or also include for this process, side
Method, article or the intrinsic key element of equipment.In the absence of more restrictions, limited by sentence "including a ..."
Key element, it is not excluded that other identical element in the process including the key element, method, article or equipment also be present.
The illustrative embodiments of the disclosure are particularly shown and described above.It should be appreciated that the disclosure is unlimited
