As depicted in figs. 1 and 2, some teeth portion A2 that existing stator core comprises ring-shaped yoke portion A1 and stretches out from ring-shaped yoke portion A1 toward inner side, line embedding groove A3 is formed between adjacent two teeth portion A2, there is following weak point in existing stator core construction: 1) the width b in ring-shaped yoke portion is wider, volume circle difficulty, is not suitable for the volume circle scheme adopting conventional bar shaped stator punching; 2) the line embedding groove A3 of stator core is little, under the stator punching deployed condition of bar shaped, the spacing d of adjacent two teeth portion is excessive, in process of production, be the stator punching of arrangement two bar shapeds in one piece of iron core steel plate, the stator punching of two bar shapeds is staggered and merged together mutually, and the teeth portion of one of them stator punching extend into inside the gap between adjacent two teeth portion of another stator punching, if the spacing of adjacent two teeth portion is too large, raw-material waste can be caused in process of production.
Summary of the invention:
The purpose of this utility model is to provide the motor of a kind of stator core and application thereof, and this stator core construction and production technology simply, can reduce raw-material use, lower production cost, improve the market competitiveness;
This electric machine structure is simple and production technology is simple, and production cost is low, and the market competitiveness is strong.
The purpose of this utility model is achieved by following technical proposals.
A kind of stator core, comprise yoke portion annulus and teeth portion annulus, described teeth portion annulus rolls up circle by the first bar shaped stator punching to form, comprise yoke portion and past several projecting inward teeth spaced apart inside yoke portion, form line embedding groove between adjacent two teeth, teeth portion annulus is nested in inside yoke portion annulus and is spliced to form stator core.
Yoke portion annulus described above rolls up circle by the second bar shaped stator punching to form.
Yoke portion annulus inner circumferential described above distributes several otch, and otch is included in V-notch under the second bar shaped stator punching deployed condition and circular hole composition.
The distance range of adjacent 2 teeth described above is between 6.0mm to 7.00mm.
The distance range of line embedding groove bottom land described above and yoke portion outer ledge is between 0.5mm to 1.5mm.
The connecting portion of the first bar shaped stator punching described above and the second bar shaped stator punching volume circle rearward end is fixed together by welding.
A kind of motor, comprise rotating shaft, permanent magnet rotor component, stator module and case component, permanent magnet rotor component and stator module form magnetic lotus root and close, stator module comprises stator core and is wound on coil windings on stator core, and described stator core is the structure of claim 1 to 6 described by any one.
The utility model compared with prior art, has following effect:
1) the teeth portion annulus described in rolls up circle by the first bar shaped stator punching to form, comprise yoke portion and past several projecting inward teeth spaced apart inside yoke portion, line embedding groove is formed between adjacent two teeth, teeth portion annulus is nested in inside yoke portion annulus and is spliced to form stator core, this stator core construction and production technology simple, raw-material use can be reduced, lower production cost, improve the market competitiveness;
2) yoke portion annulus rolls up circle by the second bar shaped stator punching to form, and compared to the stator core of traditional structure, at utmost can reduce raw-material use in Shangdi, reduce production cost;
3) yoke portion annulus inner circumferential distributes several otch, and otch is included in V-notch under the second bar shaped stator punching deployed condition and circular hole composition, and structure is simple, is instant rolledly coiled into circle;
4) distance range of line embedding groove bottom land and yoke portion outer ledge is between 0.5mm to 1.5mm, effectively prevent because yoke portion is too thick and cause the first bar shaped stator punching to be difficult to be wound into circle, ensure that the first bar shaped stator punching is easily wound into circle, technique is simple, and production efficiency is high;
5) connecting portion of stator punching volume circle rearward end is fixed together by welding, and structure is simple, and reliability is high.
