Description
Technical field
The utility model relates to axial cloth and equates electrode structure switched reluctance machines field, relates in particular to a kind of interior core stamping with angle modulation double wedge that is applied to this field motor.
Background technology
Conventional motors as asynchronous machine, magneto, switched reluctance machines be all circumferential cloth phase, each phase winding is equidistantly evenly distributed on iron core circumference, alternate mechanical angle forms by point phase winding, size is adjusted by number of poles.
But equate electrode structure switched reluctance machines for axial cloth, if the patent No. is that axial cloth as described in " 2015206867706 " equates as described in electrode structure switched reluctance machines, motor has multipair stator core and rotor core, and along motor shaft to paired distribution, a pair of iron core forms a phase, alternate mechanical angle need to be adjusted by outer iron core and motor casing, or need to adjust by interior iron core and motor shaft, but the interior core stamping of conventional art does not have corresponding design requirement, thereby design a kind of interior core stamping that can be conducive to form alternate mechanical angle, also be the technical problem of being badly in need of solution.
Summary of the invention
In order to improve the deficiencies in the prior art and the function that realizes new technology, the purpose of this utility model is to provide a kind of interior core stamping with angle modulation double wedge, this interior core stamping with angle modulation double wedge coordinates installation by double wedge is set at endoporus with the transposition of motor shaft groove, thereby facilitates the each phase iron core of motor to form alternate mechanical angle.
The utility model is that the technical scheme that its technical problem of solution adopts is: a kind of interior core stamping with angle modulation double wedge, equate electrode structure switched reluctance machines for axial cloth, number of motor phases is q, q >=3 are also natural number, it laminates into iron core and is installed on motor shaft, described motor shaft cylindrical is provided with multiple grooves that are used to form alternate mechanical angle, the corresponding alternate mechanical angle of adjacent described groove angle, the described interior core stamping cylindrical with angle modulation double wedge is provided with salient pole, quantity is P, P >=4 are also even number, the described interior core stamping endoporus with angle modulation double wedge is provided with double wedge, described double wedge forms alternate mechanical angle for coordinating to install with described groove transposition.
Further, described double wedge quantity < P.
Further, described double wedge is rectangular teeth.
Further, described double wedge root is provided with the groove of stepping down.
Principle of the present utility model is: equate electrode structure switched reluctance machines for axial cloth, the interior iron core of the outer iron core adjustment of can aliging and motor shaft form alternate mechanical angle, the described interior core stamping with angle modulation double wedge laminates into iron core, each phase iron core coordinates installation by described double wedge with described groove transposition, just can form alternate mechanical angle.
The beneficial effects of the utility model are: respective shaft equates electrode structure switched reluctance machines to cloth, have opened up a kind of simple interior core stamping structure, can facilitate the each phase iron core of motor to form alternate mechanical angle.
Brief description of the drawings
Fig. 1 is the three-phase installment state schematic diagram of the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment.
In figure, the implication of mark is: 10. the interior core stamping with angle modulation double wedge, 11. salient poles, 12. double wedges, 13. grooves of stepping down, 20. motor shafts, 21. grooves.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 and embodiment illustrated in fig. 2 in, a kind of interior core stamping 10 with angle modulation double wedge, equate electrode structure switched reluctance machines for axial cloth, number of motor phases is q, q >=3 are also natural number, q=3 in embodiment, it laminates into iron core and is installed on motor shaft 20, motor shaft 20 cylindricals are provided with multiple grooves 21 that are used to form alternate mechanical angle, the corresponding alternate mechanical angle of adjacent notches 21 angles, alternate mechanical angle is 360 °/qP, interphase cycle angle is 360 °/P, because arbitrary phase iron core rotates through k(k=0, 1, 2, ) behind individual interphase cycle angle, iron core is alignment again just, therefore the corresponding alternate mechanical angle of adjacent notches 21 angles can have multiple choices, be adjacent notches 21 angle=360 °/qP ± k*360 °/P, need k can get different value according to structure, k=1 in embodiment, interior core stamping 10 with angle modulation double wedge is provided with salient pole 11 at cylindrical, quantity is P, P >=4 are also even number, P=8 in embodiment, interior core stamping 10 with angle modulation double wedge is provided with double wedge 12 at endoporus, double wedge 12 forms alternate mechanical angle for coordinating to install with groove 21 transpositions, in embodiment, adjacent notches 21 angles are 60 °.
In the utility model embodiment, double wedge 12 quantity are 1 < 8, and less double wedge quantity can make processing and assembling simple.
In the utility model embodiment, double wedge 12 is rectangular teeth, compares involute teeth, lance tooth processing simply, and bearing torque is large.
In the utility model embodiment, double wedge 12 roots are provided with the groove 13 of stepping down, and can make motor casing groove without chamfering.
The principle of the utility model embodiment is: equate electrode structure switched reluctance machines for axial cloth, the interior iron core of the outer iron core adjustment of can aliging and motor shaft form alternate mechanical angle, the described interior core stamping with angle modulation double wedge laminates into iron core, each phase iron core coordinates installation by described double wedge with described groove transposition, just can form alternate mechanical angle, in embodiment, A, B, C tri-phase iron core replace and are assembled to respectively on 3 grooves 21 with same double wedge 12, and A, B, C tri-phase iron core have just formed alternate mechanical angle.
The beneficial effect of the utility model embodiment is: the axial cloth of corresponding three-phase equates electrode structure switched reluctance machines, has opened up a kind of simple interior core stamping structure, can facilitate motor tri-phase iron core to form alternate mechanical angle.
The above is only the utility model description preferred embodiment; should be understood that the finiteness due to literal expression; and objectively there is unlimited concrete structure; for this area those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection domain of the present utility model.
