Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase Mutually combination.
In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower, top, bottom " is usually needle For direction shown in the drawings either for it is vertical, on vertical or gravity direction for each component mutual alignment relation Word is described.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Present embodiments provide for a kind of stator cores 11.As shown in Figure 1, the stator core 11 includes iron core outer ring portion 117.The first stator tooth 111 and second for being formed with opposed type arrangement in the iron core outer ring portion 117 and inwardly stretching out toward each other Stator tooth 112, and between the first stator tooth 111 and the second stator tooth 112 and the first rotor arranged in parallel peace Fill hole 113 and the second rotor mounting hole 114.The hole line of centres side of the first rotor mounting hole 113 and the second rotor mounting hole 114 Direction is stretched out to perpendicular to the opposed type of the first stator tooth 111 and the second stator tooth 112.
When the winding mode of stator winding is reasonable, the unique stator odontoid of stator core 11 can be guided effectively by fixed The magnetic induction line trend for the stator field that sub- winding energization generates, that is, enable the magnetic induction line to be distributed in first turn relatively independently In sub- mounting hole 113 and the second rotor mounting hole 114.In this way, in the first rotor mounting hole 113 and the second rotor mounting hole 114 In two rotor assemblies accordingly installing can be pivoted independently of each other under electromagnetic action, and put down from two rotor assemblies Two motor shafts that row stretches out need not be also driven by the mechanical structure of additional form, effectively low to have subtracted when motor works Noise.In addition, the structure of the stator core 11 of present embodiment is more simple compared with structures such as machine drivings, life is advantageously reduced Difficulty is produced, to improve production efficiency and reduce production cost.
Under some specific work condition environments, it may be necessary to which two motor shafts of motor all have roughly the same output work Rate.At this point, the first stator tooth 111 of stator core 11 and the second stator tooth 112 can be preferably arranged to shape it is identical and about Hole line of centres symmetrical structure, so that stator field be made to be evenly distributed on the first rotor mounting hole 113 and the installation of the second rotor In hole 114, that is, there is roughly the same magnetic field shape and magnetic density.At this point, the global shape of stator core 11 is also more It is well-balanced, it is ensured that motor has the shape of preferable inner space utilization rate and generous beauty.
Specifically, the addendum line 118 of the first stator tooth 111 includes the portion perimeter circular arc line of the first rotor mounting hole 113 With the portion perimeter circular arc line of the second rotor mounting hole 114, and in the shape phase of the first stator tooth 111 and the second stator tooth 112 Together and about in the symmetrical situation of the hole line of centres, the tooth top wire shaped of the two is also identical.The shape of the addendum line can Make that there is smaller air gap between stator tooth and rotor assembly, is more advantageous to distribution of the stator field in rotor mounting hole.
Further, the tooth crest of the first stator tooth 111 is equipped with towards the first rotor mounting hole 113 and the second rotor and installs The center corner 115 that intermediate air gap between hole 114 extends.It should be noted that the center corner 115 is exactly by the At the top of the portion perimeter circular arc line cutting teeth of the portion perimeter circular arc line of one rotor mounting hole 113 and the second rotor mounting hole 114 And formed.When two portion perimeter circular arc lines intersect or is tangent, the top of center corner 115 is formed as pointed shape Shape;When two portion perimeter circular arc lines are non-intersecting, the top of center corner 115 is then formed as approximate angular shape, this When two portion perimeter circular arc lines between spacing should not be too large, otherwise will cause stator field at center corner 115 Magnetic density is excessive, so that the stress between two rotor assemblies be caused to interfere.
In addition, tooth crest is additionally provided with the tooth boot portion 116 for being formed in the two sides of center corner 115, the tooth boot portion 116 is in packet Extend around shape along the periphery circular arc line of the first rotor mounting hole 113 or the second rotor mounting hole 114.The setting of tooth boot portion 116 Be conducive to expand overlay area of the stator field in the first rotor mounting hole 113 or the second rotor mounting hole 114, it is ensured that rotor Assembly can improve the job stability of motor sustainedly and stably rotate at high speed.
It can be seen from the above, to avoid two rotor assemblies in the first rotor mounting hole 113 and the second rotor mounting hole 114 Stress interference is generated, the stator field distribution at center corner 115 should be reduced to the greatest extent.In addition to as far as possible by center corner 115 are set as except tip shape, can also be by the middle apex of the heart of the center corner 115 of the first stator tooth 111 and the second stator tooth 112 Corner 115 is preferably arranged to the structure that interval disconnects.Under this structure, two can exist between apex of the heart corner 115 among the above compared with Big air gap, and the magnetic conductivity of air gap is smaller for the magnetic conductivity of stator core 11, to make the first rotor mounting hole 113 and the second transitional region between rotor mounting hole 114 almost without covering stator field, avoid two rotor assemblies it Between there is the case where stress interference, it is ensured that two rotor assemblies can pivot independently of each other.
But the spacing of two centers corner 115 is also unsuitable too small, otherwise can be covered on the first rotor mounting hole 113 Or second effective stator field region in rotor mounting hole 114 becomes smaller.Hereby, in the present embodiment by the first stator tooth The spacing of 111 center corner 115 and the center corner 115 of the second stator tooth 112 is preferably arranged to 5mm~8mm.
Further, identical as the shape of the second stator tooth 112 in the first stator tooth 111 and symmetrical about the hole line of centres In the case where, two rotor assemblies being mounted in the first rotor mounting hole 113 and the second rotor mounting hole 114 in order to prevent exist It is interfered when rotation, in the radius R of the first rotor mounting hole 113, the radius r of the second rotor mounting hole 114 and hole It is set as meeting relationship between the length s of heart line: s > r+R.
