Abstract
The invention discloses a rotor plastic package mechanism of a novel switched reluctance motor. The rotor plastic package mechanism comprises a rotor yoke part and a plurality of salient poles, wherein the plurality of salient poles are evenly distributed on the periphery of the rotor yoke part; rotor slots are arranged between adjacent salient poles; a plastic package body is arranged in each rotor slot; the outer side wall of each plastic package body is laminated with the inner side wall of the corresponding rotor slot; and a hollow inner cavity is formed in each plastic package body. Only the outside of the rotor slots is plastically packaged, so that the quality of a molding compound is reduced to the maximal extent while the plastic package strength is ensured; and the material cost of the motor is reduced.
Description
Technical field
The present invention relates to switched reluctance machines, especially a kind of novel switched reluctance motor rotor plastic package mechanism.
Background technology
Switched reluctance machines, as a kind of New-type electric machine, has obtained sufficient utilization in many occasions, owing to rotor structure is very simple, rotor does not has winding, magnet steel or magnet ring；The rotor operation frequency of switched reluctance machines is identical with the energising frequency of stator；Switched reluctance machines, just with the reluctance torque of motor, does not has permanent magnetic field, need not weak magnetic at a high speed；Therefore, switched reluctance machines is especially suitable for applying to occasion at a high speed.
As it is shown in figure 1, the rotor of existing switched reluctance machines uses salient-pole structure 20, making motor in the running, the wind moussing loss of motor can increase along with the increase of rotating speed.For high-speed electric expreess locomotive, the wind moussing loss accounting of motor is higher, has a strong impact on the efficiency of motor.Switched reluctance machines, when high-speed cruising, causes the air agitation within machine cavity serious, produces serious aerodynamic noise.
In order to improve this problem, the rotor plastic packaging of traditional switched reluctance machines is all to use overall plastic packaging part 10 to fill rotor slot, so increase the rotary inertia of switch reluctance machine rotor, slowed down switched reluctance machines mechanical speed response, make motor in application scenarios such as quick acceleration and deceleration, occur in that the delayed of machinery, be not easy to the quick control of motor.The most overall plastic packaging also can increase the material cost of switched reluctance machines.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of novel switched reluctance motor rotor plastic package mechanism.
The technical solution used in the present invention is:
A kind of novel switched reluctance motor rotor plastic package mechanism, including rotor yoke and multiple salient poles of being evenly distributed on rotor yoke week edge, it it is rotor slot between Adjacent salient poles, a plastic-sealed body it is provided with in each rotor slot, fit with rotor slot medial wall in each plastic-sealed body lateral wall, and plastic-sealed body inside is hollow lumen.
The size of described plastic-sealed body is mated with rotor slot, and plastic-sealed body is injection mo(u)lding.
Beneficial effects of the present invention:
The present invention uses half plastic package structure, border just for rotor slot carries out limited plastic packaging, in the case of meeting the intensity of plastic packaging, the quality of plastic packaging part can be effectively reduced, reduce the high-speed cruising of the rotary inertia of rotor, beneficially switched reluctance machines to greatest extent, and owing to being half plastic packaging, the most significantly reduce in the usage amount of capsulation material, save the material cost of motor plastic package.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described.Obviously, described accompanying drawing is a part of embodiment rather than whole embodiment of the present invention, and those skilled in the art is under accompanying drawing illustrates premise, it is thus achieved that other designs and accompanying drawing:
Fig. 1 is the schematic diagram of Conventional switched reluctance rotor plastic package mechanism；
Fig. 2 is the top view of switch reluctance machine rotor plastic package mechanism of the present invention；
Fig. 3 is the axonometric chart of switch reluctance machine rotor plastic package mechanism of the present invention.
Detailed description of the invention
With reference to shown in Fig. 2, Fig. 3, a kind of novel switched reluctance motor rotor plastic package mechanism for the present invention, including rotor yoke 1 and multiple salient poles 2 of being evenly distributed on 1 week edge of rotor yoke, it it is rotor slot between Adjacent salient poles 2, the plastic-sealed body 3 of an injection mo(u)lding it is provided with in each rotor slot, the size of each plastic-sealed body 3 is mated with rotor slot to fit with rotor slot medial wall in plastic-sealed body 3 lateral wall, and plastic-sealed body 3 inside is hollow lumen 4.
This plastic-sealed body 3 is molded into one by the plastic packaging material of the upper and lower end parts of rotor Yu rotor slot portion, and is internally formed described hollow lumen 4 in rotor slot, is effectively increased the plastic packaging intensity of rotor；Due to the formation of hollow lumen 4, capsulation material is saved, and reduces plastic packaging cost；Due to the formation of hollow lumen 4, the increase of the rotary inertia that the plastic package rotor effectively reduced brings.
As mentioned above, the present invention uses the hollow plastic-sealed body 3 of half plastic package structure, border just for rotor slot carries out limited plastic packaging, in the case of meeting the intensity of plastic packaging, the quality of plastic packaging part can be effectively reduced, reduce the rotary inertia of rotor to greatest extent, be conducive to the high-speed cruising of switched reluctance machines, and owing to being half plastic packaging, the most significantly reduce in the usage amount of capsulation material, save the material cost of motor plastic package.
The foregoing is only the preferred embodiments of the present invention, the present invention is not limited to above-mentioned embodiment, as long as realizing within the technical scheme of the object of the invention broadly falls into protection scope of the present invention with essentially identical means.
