Embodiment
Core of the present utility model is to provide a kind of stator core, with the noise reduced in electric machine rotation process. Another core of the present utility model is to provide a kind of stator of this stator core and have motor and the compressor of this stator of having.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only the utility model part embodiment, instead of whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in figures 3 to 6, the utility model discloses the stator core of a kind of stator, comprise the teeth portion along stator outer shroud axial distribution, and this teeth portion comprises the teeth portion main body being connected with stator outer shroud 1 and is arranged in the first crown 21 and the 2nd crown 22 of teeth portion main body both sides, wherein, first crown 21 is greater than the end face of the 2nd crown 22 away from stator outer shroud 1 to the distance of axis stator away from the end face of stator outer shroud 1 to the distance of axis stator, and the first crown 21 is adjacent with the 2nd crown 22 of adjacent teeth portion, i.e. the first crown 21 and the 2nd alternate layout of crown 22. First crown 21 is set to be greater than by the application the end face of the 2nd crown 22 away from stator outer shroud 1 away from the end face of stator outer shroud 1 to the distance of axis stator to the distance of axis stator, the end face of the first crown 21 can be made to be greater than the distance of end face to rotor periphery of the 2nd crown 22 to the distance of rotor periphery, thus increase the air gap length between stators and rotators, in this sense of rotation, reach the reactive force reducing and being subject to, slow down the time of the first crown by power, reduce the impact on motor performance; In addition, make uniform force, avoid that the position by power sudden change occurs, thus reduce noise.
For the relative position of the first crown 21 and the 2nd crown 22, can arrange according to the direction of motor rotor, concrete, as shown in Figure 3 and Figure 4, when stator rotates counterclockwise, the first crown 21 crown of first process in whole teeth portion in turning direction; As shown in Figure 5 and Figure 6, when stator rotates clockwise, the first crown 21 is the crown of first process in whole teeth portion in turning direction.
In further embodiment, the end face away from stator outer shroud 1 of the first crown 21 is tilted to stator outer shroud 1 direction to the side away from teeth portion main body by the side near teeth portion main body.
