Description
Technical field
The present invention relates to rotor, especially a kind of novel rotor with salient pole formula electric machine structure.
Background technology
The motor of rotor with salient pole formula structure has utilization in a lot of occasions, such as switched reluctance machines, the exchange of electrical excitation
Synchronous motor etc.；Particularly apply to switched reluctance machines, owing to its rotor structure is simple, rotor does not has Exciting Windings for Transverse Differential Protection and
Permanent magnet, thus can preferably be applicable to the more severe occasion of environmental requirement；But due to the structure of rotor with salient pole formula, electricity can be made
Machine wind moussing loss operationally strengthens, and wind moussing loss can increase with the increase of rotating speed, reduces the efficiency of motor.
Existing method is directly to carry out plastic packaging, when plastic packaging material runs with rotor, plastic packaging material on rotor core
It is easily thrown out of because of self excessive centrifugal force, affect the security and stability of motor.
Content of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of novel rotor with salient pole formula electric machine structure.
The technical solution used in the present invention is:
A kind of novel rotor with salient pole formula electric machine structure, including rotor yoke and be evenly distributed on rotor yoke week edge multiple
Salient pole, is rotor slot between Adjacent salient poles, is provided with a plastic-sealed body and at least for preventing plastic-sealed body from getting rid of in this rotor slot
The madial wall laminating of the fixed card slot going out, this plastic-sealed body lateral wall and rotor slot and fixed card slot thereof.
Further, the fixed card slot in described either rotor groove has three, and this three fixed card slots are respectively arranged at and turn
The bottom of pilot trench and two side.
Further, described plastic-sealed body is molded into one by the plastic packaging material of the upper and lower end parts of rotor and rotor slot portion.
Further, described plastic-sealed body is internal is hollow lumen.
The minimum widith H1=of described salient pole*/, wherein,For the air gap flux density of rotor with salient pole formula motor,For electricity
Machine rotor tooth square,Close for rotor tooth magnetic.
Beneficial effects of the present invention:
The present invention is applicable to the motor of all of rotor with salient pole formula, and fixed card slot design can lock plastic-sealed body, effectively reduce
The risk that when motor runs, rotor plastic packaging material is thrown out of；The hollow design of plastic-sealed body can reduce traditional rotor plastic packaging and bring
The increase degree of centrifugal force and rotary inertia.
Brief description
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, required in embodiment being described below make
Accompanying drawing be briefly described.Obviously, described accompanying drawing is a part of embodiment of the present invention, rather than all implements
Example, those skilled in the art is under the premise of brief description, it is thus achieved that other designs and accompanying drawing:
Fig. 1 is the schematic diagram of tradition salient pole type rotor lamination structure；
Fig. 2 is the schematic diagram of salient pole type rotor lamination structure of the present invention；
Fig. 3 is the stereogram of rotor with salient pole formula electric machine structure of the present invention；
Fig. 4 is the sectional view of rotor with salient pole formula electric machine structure of the present invention.
Detailed description of the invention
It with reference to shown in Fig. 2-Fig. 4, is a kind of novel rotor with salient pole formula electric machine structure of the present invention, including rotor yoke 1
And it is evenly distributed on multiple salient poles 2 on 1 week edge of rotor yoke, it is rotor slot 3 between Adjacent salient poles 2, arrange in this rotor slot 3
Have a plastic-sealed body 4 and three fixed card slots 5 for preventing plastic-sealed body 4 from throwing away, this plastic-sealed body 4 lateral wall and rotor slot 3 and
The madial wall laminating of its fixed card slot 5.
The design of above-mentioned fixed card slot 5 can lock plastic-sealed body 4, effectively reduces rotor plastic packaging material when motor runs and is got rid of
The risk going out；This three fixed card slots 5 are respectively arranged at bottom and the two side of rotor slot 3, certainly, the number of fixed card slot 5
Being three preferred as just the present embodiment, limiting not as concrete, other numbers are also applied for the present invention.
As the improvement further of the technical program, described plastic-sealed body 4 is moulded by the upper and lower end parts of rotor and rotor slot 3
Envelope material is molded into one, and plastic-sealed body 4 inside is hollow lumen 6, is effectively increased the plastic packaging intensity of rotor；Due to cavity
Being formed, capsulation material is saved, and reduces plastic packaging cost；Due to the formation of cavity, the plastic package rotor band effectively reducing
The increase of the rotary inertia coming.
Such as Fig. 2, the minimum widith H1=of rotor with salient pole 2*/, wherein,Air gap magnetic for rotor with salient pole 2 formula motor
It is close,For rotor tooth square,Close for rotor tooth magnetic, depending on this value is according to rotor silicon steel material.
As described above, the present invention is applicable to the motor of all of rotor with salient pole 2 formula, fixed card slot 5 design can lock moulds
Envelope body 4, effectively reduces the risk that when motor runs, rotor plastic packaging material is thrown out of；The hollow design of plastic-sealed body 4 can reduce
The centrifugal force that traditional rotor plastic packaging brings and the increase degree of rotary inertia.
The foregoing is only the preferred embodiments of the present invention, the present invention is not limited to above-mentioned embodiment, as long as with
Essentially identical means realize that the technical scheme of the object of the invention broadly falls within protection scope of the present invention.
