Description
Technical field
The utility model relates to technical field of motors, specifically a kind of switched reluctance machines structure for reducing vibration noise.
Background technique
Switched reluctance machines have obtained fast in recent years because the advantages that its structure is simple, the range of speeds is wide receives significant attention
Still since the double-salient-pole structure of its own and the nonlinearity of winding current are brought, torque pulsation is big, noise is big for speed development
The drawbacks of, it is limited in the application of numerous areas, and vibration noise is as caused by torque pulsation, if by torque pulsation
The problem of solve, can exert far reaching influence to traditional motor speed regulation system.
Utility model content
The utility model aim is to provide a kind of switched reluctance machines structure for reducing vibration noise, to solve existing switch
The reluctance motor big problem of vibration noise in the process of running.
Technical solution used by the utility model is a kind of switching magnetic-resistance for reducing vibration noise in order to achieve the above objectives
Electric machine structure, structure optimization include stator, rotor two large divisions, and the stator teeth is inserted with magnetic barrier, and tooth tip two sides, which increase, to be had
Pole shoe, tooth tip two sides pole shoe lower section are provided with arc groove, and magnetic barrier is inserted in the rotor tooth of the rotor.
In above-mentioned technical proposal, the stator magnet barrier is that air magnetic hinders, and is distributed in inside each stator tooth.
In above-mentioned technical proposal, in the two sides of stator tooth tip, width is greater than the stator facewidth for the pole shoe addition.
In above-mentioned technical proposal, the arc groove is below pole shoe, stator tooth two sides are symmetrical.
In above-mentioned technical proposal, the rotor magnetic barrier is that air magnetic hinders, and is distributed in inside each rotor tooth.
By using above-mentioned technical proposal, switched reluctance machines obtain good operation characteristic, and stator tooth is inserted into magnetic barrier can
To increase magnetic flux density in tooth to increase torque, and be conducive to motor radiating, it is changeable that stator tooth top two sides increase pole shoe
Energization pole magnetic flux path and size increase polar arc to reduce magnetic circuit saturation, reduce torque pulsation and reduce vibration noise, stator tooth
Arc groove is opened in two sides can weaken radial Reeb, reduce motor oscillating；Magnetic flux radial component becomes tangential when rotor tooth insertion magnetic barrier
Component is to reduce torque pulsation, achievees the purpose that increase average torque, reduces motor oscillating.
Detailed description of the invention
Attached drawing 1 is a kind of switched reluctance machines structural schematic diagram for reducing vibration noise of the utility model.
In figure: 1, stator, 2, stator tooth magnetic barrier, 3, arc groove, 4, pole shoe 5, rotor, 6, rotor tooth magnetic barrier.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Referring to Figure of description 1, the electric machine structure point of a kind of switched reluctance machines structure reducing vibration noise, optimization is fixed
Son, rotor two large divisions；The stator teeth is inserted with magnetic barrier, and tooth tip two sides, which increase, pole shoe, below the pole shoe of tooth tip two sides
It is provided with arc groove, magnetic barrier is inserted in the rotor tooth of the rotor.
The stator structure is inserted with magnetic barrier inside each stator tooth, and each stator tooth tip two sides, which increase, pole shoe, and
And arc groove is provided with below the pole shoe of tooth tip two sides.
By using above-mentioned technical proposal, switched reluctance machines obtain good operation characteristic, and stator tooth is inserted into magnetic barrier can
To increase magnetic flux density in tooth to increase torque, and be conducive to motor radiating, it is changeable that stator tooth top two sides increase pole shoe
Energization pole magnetic flux path and size increase polar arc to reduce magnetic circuit saturation, reduce torque pulsation and reduce vibration noise, stator tooth
Arc groove is opened in two sides can weaken radial Reeb, reduce motor oscillating；Magnetic flux radial component becomes tangential when rotor tooth insertion magnetic barrier
Component can be such that torque pulsation reduces, and achieve the purpose that increase average torque, reduce motor oscillating.
The magnetic barrier being inserted into inside stator tooth can increase magnetic flux density and increase average torque, and can be in motor operation
Hinder export heat by magnetic, edge effect and magnetic circuit saturated phenomenon often occur for motor stator tooth crest, in motor stator tooth
Increased pole shoe can change magnetic flux path, disperse the magnetic flux density of tooth top, and weakening torque ripple reduces vibration noise, in stator
Arc groove is opened in tooth two sides, and magnetic flux can be allowed more excessively to pole shoe, can also to weaken surface radial direction flux density, reduce motor vibration
It is dynamic；Insertion air magnetic barrier can become the radial component of magnetic flux tangential component inside rotor tooth, go back while increasing torque
Weakening radial force reduces motor torque ripple, achievees the purpose that reduce vibration noise with this.
This embodiment is just an exemplary description of this patent, does not limit its protection scope, those skilled in the art
Member can also be changed its part, as long as it does not exceed the essence of this patent, within the protection scope of the present patent.
