Abstract
The utility model relates to a mosaic-type stator core mainly composed of a core outer ring obtained through non-oriented electrical steel stamping or splicing and a tooth space made of oriented electrical steel. An inner side of the core outer ring is provided with a cooperative yoke portion used for splicing the tooth space. Compared with the prior art, the mosaic-type stator core is designed to be small-size by use of high magnetic sense of the oriented electrical steel in a certain rolling direction, and to be highly efficient by use of low iron loss of the oriented electrical steel in a certain rolling direction; by use of mosaic process, the mosaic-type stator core allows full play to the advantages of performance of the non-oriented electrical steel and the oriented electrical steel, and therefore enables a more flexible structure, a greatly simplified punch die and an improved utilization rate of electromagnetic steel.
Description
Technical field
The utility model relates to a kind of stator core, especially relates to a kind of spliced stator core.
Background technology
Stator core about electric rotating machine is used has proposed multiple implementation method in the prior art.Disclose a kind of stator core in the TOHKEMY 2006-352991 patent documentation, at an end of banded iron core blank depressed part has been set, at its opposite end face protuberance has been set, made under its situation that is deformed into tubular its chimeric connection.But, because at present the electromagnetic steel plate that generally uses of motor industry mostly is non-oriented electrical steel, its under B50 maximum magnetic flux thoroughly mostly about 1.7T.Under big electric current operating mode, electric machine iron core magnetic saturation phenomenon is serious.Be unfavorable for the raising of motor output torque, the motor iron loss also will significantly improve, and restrict the motor high efficiency, the miniaturization design.
The utility model content
The purpose of this utility model is exactly to provide a kind of miniaturization, high efficiency, structure that the spliced stator core of flexibility is more arranged for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of spliced stator core comprises:
The iron core outer shroud: obtained by non-oriented electrical steel punching press or splicing, the inboard arranges the yoke portion that cooperates;
Teeth groove: obtain by there being oriented electrical steel to make, be fastened in the cooperation yoke portion of iron core outer shroud inboard.
Described iron core outer shroud is the outer shroud that direct punching press obtains.
Described iron core outer shroud is the outer shroud that the segmented that obtains of stamping-out connects.
Described iron core outer shroud is the outer shroud that the chain type that obtains of stamping-out connects.
Described iron core outer shroud is circle, quadrangle, hexagon or other shape.
The inboard of described iron core outer shroud is provided with the cooperation yoke portion that doubly several cards of 3 are established teeth groove.
Described cooperation yoke portion is provided with 6,9 or 12 etc.
Described teeth groove is to have oriented electrical steel to control at 30 ° of teeth groove that obtain with interior making by the steel rolling direction.
Compared with prior art, the utlity model has following advantage:
(1) utilization has oriented electrical steel necessarily rolling the high magnetic strength that makes progress, and reaches the miniaturization purpose of design;
(2) utilization has oriented electrical steel necessarily rolling upwards low iron loss, reaches the high efficiency purpose of design;
(3) stator core adopts splicing process, gives full play to non-oriented electrical steel and the advantage performance that oriented electrical steel is arranged, and structure more has flexibility.
(4) simplify punching machine mold greatly, improve the electromagnetic steel plate utilance.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of spliced stator core, its structure as shown in Figure 1, this stator core mainly is made up of iron core outer shroud 1 and teeth groove 2.Wherein, iron core outer shroud 1 is obtained by non-oriented electrical steel punching press or splicing, and the inboard arranges the yoke portion that cooperates.Teeth groove 2 obtains by there being oriented electrical steel to make, and is fastened in the cooperation yoke portion of iron core outer shroud 1 inboard.The present embodiment utilization has oriented electrical steel necessarily rolling on direction, have high magnetic strength, low iron loss characteristic, be made into the teeth groove 2 of electric machine iron core, the iron core outer shroud 1 in the outside adopts non-oriented electrical steel to make and realizes non-oriented electrical steel and have the mixing of oriented electrical steel to use.For adopting teeth groove 2, its structure has been utilized as oriented electrical steel and has obtained with interior making at 30 ° by the control of steel rolling direction as shown in Figure 2.For the iron core outer shroud 1 that uses, can be the outer shroud that direct punching press obtains, as shown in Figure 3, or the outer shroud that connects of the segmented that obtains of stamping-out, as shown in Figure 4, also can be the outer shroud that chain type that stamping-out obtains connects, as shown in Figure 5.In addition, iron core outer shroud 1 can adopt circle, quadrangle, hexagon or other shape, and the inboard is provided with the cooperation yoke portion that doubly several cards of 3 are established teeth groove, for example can be 6,9,12 etc.In the present embodiment, the annulus that the iron core outer shroud 1 of employing obtains for direct punching press, inside is provided with six and cooperates yoke portion, is arranged with six teeth groove 2.
Claims (8)
1. a spliced stator core is characterized in that, this stator core comprises:
