Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, stator core of the present invention and motor are further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, a kind of stator core, comprises teeth portion 1 and yoke portion 2;
Teeth portion 1 is torus, and arranges some stator rabbets 3;
Yoke portion 2 is tubular;
Yoke portion 2 is set in teeth portion 1, and removably connects with teeth portion 1;
The material of teeth portion 1 is high permeability material.
Be set in teeth portion 1 by adopting yoke portion 2, and to removably connect such frame mode with teeth portion 1, the material of teeth portion 1 is high permeability material costly, the iron loss of teeth portion 1 can be reduced, and yoke portion 2 can adopt the common material that cost is comparatively cheap, under guarantee motor performance prerequisite, can reduce costs like this.
As a kind of embodiment, the material of teeth portion 1 is silicon steel.
The material of teeth portion 1 is silicon steel, can improve the torque density of motor, reduces the iron loss of teeth portion 1, and cost is relatively cheap simultaneously.
As a kind of embodiment, the excircle of teeth portion 1 is arranged connection bump 4;
The inwall in yoke portion 2 is arranged connecting groove 5;
Connection bump 4 is suitable with connecting groove 5, and embeds in connecting groove 5, for teeth portion 1 being fixedly connected with yoke portion 2.
Embedded in connecting groove 5 by connection bump 4 and teeth portion 1 is fixedly connected with yoke portion 2, the fastness making to connect between teeth portion 1 and yoke portion 2 can be ensured, thus ensure that the normal operation of motor, what also make the installment work in teeth portion 1 and yoke portion 2 become is more simple, convenient simultaneously.
As a kind of embodiment, the quantity of connection bump 4 is at least 2, is distributed on the excircle of teeth portion 1;
The quantity of connecting groove 5 is identical with the quantity of connection bump 4, and with connection bump 4 one_to_one corresponding.
2, teeth portion 1 and yoke portion can be made like this to be fixedly connected with more stable, more to efficiently avoid the phenomenon that relative displacement appears getting loose or producing in teeth portion 1 and yoke portion 2, ensure that the normal operation of motor.
As a kind of embodiment, the shape of connection bump 4 is trapezoidal and/or rectangle and/or arc;
The shape of the connection bump 4 that the shape of connecting groove 5 is corresponding with it is suitable.
The processing and fabricating of connection bump 4 and connecting groove 5 can be made like this to become more simple.
As a kind of embodiment, as shown in Figure 3, some stator rabbets 3 are arranged on the excircle of teeth portion 1.
As a kind of embodiment, as shown in Figure 2, some stator rabbets 3 are arranged on the inner periphery of teeth portion 1.
