Stator 100 according to embodiments of the present invention is described below with reference to Fig. 1-Fig. 3.As shown in Figure 1-Figure 3, according to the present invention The stator 100 of embodiment includes:Stator body 1 and insulating barrier 4.
As shown in figure 1, stator 100 can include stator body 1 and stator line bag 2, wherein stator body 1 can be by multilayer The stator punching of regulation shape is stacked to be formed, and stator punching can be sheet metal, and be formed by high velocity ram machine punching.Stator Line bag 2 is arranged on the top and bottom of stator body 1, and stator line bag 2 is used for the coiling of coil, further, as shown in figure 1, Outgoing line components 3 can be provided with stator line bag 2, after coil winding is completed, end turn outgoing line components is connected to 3, so as to complete the making of stator 100.
Further, as shown in Fig. 2 the middle part of stator body 1 is provided with rotor hole 13, circular hole centered on rotor hole 13 is used In the installation for realizing rotor, while having multiple teeth portion 11 on stator body 1, multiple teeth portion 11 are circumferentially-spaced along rotor hole 13 Groove portion 12 (i.e. line embedding groove) is limited between distribution, and adjacent two teeth portion 11.
Further, line embedding groove can be multiple, and multiple line embedding grooves are radially distributed around rotor hole 13, and rule The width of groove in the trend that tapered off from the edge of stator body 1 to center, meanwhile, the one of the center of circle of close rotor hole 13 of line embedding groove End is configured to semiclosed mouth structure, is so easy to winding of the coil on stator body 1 to arrange.
Further, line embedding groove can include the first sub- line embedding groove 121, the second sub- line embedding groove 122 and the 3rd sub- rule Groove 123, the first sub- line embedding groove 121, the second sub- line embedding groove 122 and the 3rd sub- line embedding groove 123 can be multiple, specifically, such as Shown in Fig. 2, the first sub- line embedding groove 121 on stator body 1 can be two, and the second sub- line embedding groove 122 can be six, remaining Be the 3rd sub- line embedding groove 123, the sub- line embedding groove 121 of two of which first respectively positioned at the radial direction two ends of rotor hole 13, and two the One sub- line embedding groove 121 is located along the same line, and the second sub- line embedding groove 122 includes two groups, and each group of the second sub- line embedding groove 122 is three It is individual, and each group of the second sub- line embedding groove 122 set adjacent to a first sub- line embedding groove 121, the 3rd sub- line embedding groove 123 also includes two Group, each group of two sub- line embedding groove at the two ends of the 3rd sub- line embedding groove 123 respectively with the first sub- line embedding groove 121 and the second sub- rule Groove 122 is set.
Alternatively, the wire casing depth of the first sub- line embedding groove 121 is less than the wire casing depth of the 3rd sub- line embedding groove 123, and second is sub The depth of line embedding groove 122 is minimum.That is, the bottom of the first sub- line embedding groove 121 to the center of circle of rotor hole 13 distance less than the The bottom of three sub- line embedding groove 123 to the center of circle of rotor hole 13 distance, the bottom of the second sub- line embedding groove 122 to the center of circle of rotor hole 13 away from From minimum, so, the distance at bottom to the edge of stator body 1 of the first sub- line embedding groove 121 and the second sub- line embedding groove 122 is unlikely In excessively near, so as to ensure the yoke portion reasonable wide at two, iron loss is so advantageously reduced, it is to avoid magnetic is close too high, ensure motor Performance.
Further, groove portion 12 (i.e. line embedding groove) has the contact surface being suitable to enamel-cover linear contact lay, such as each teeth portion 11 two side walls and root portion (i.e. near the end at the center of rotor hole 13), can be provided with insulating barrier 4 on contact surface, can Selection of land, insulating barrier 4 may be integrally formed on stator body 1 and covering contact surface.
So, stator 100 according to embodiments of the present invention, by the contact surface with enamel-cover linear contact lay in stator body 1 Upper setting insulating barrier 4, while the insulating requirements between enamel-covered wire and stator body 1 are met, it is possible to reduce to Stator Slots 12 space hold, greatly improves the effective area of Stator Slots 12.
Alternatively, insulating barrier 4 can be formed on the whole inner surface of groove portion 12, thus can effectively realize stator body Insulation between 1 and coil, it is safe, while avoid being caused to groove portion using insulating elements such as slot insulation in groove portion 12 12 space hold, so as to substantially increase the effective area of groove portion 12, lifting motor whole efficiency.
Further, insulating barrier 4 is also formed on two end faces 15 of stator body 1, i.e., in stator body 1 and stator line Bag 2 contact two end faces 15 up and down on can also coating insulating layer 4 so that it is more that slot insulation can be avoided to be higher by stator body 1 Shortcoming, and then stator line bag 2 is completely attached to stator body 1, reduce the usage amount of the paint line bag of end, Jin Er While reduces cost, winding loss, the whole efficiency of lifting motor are reduced.
Alternatively, the insulating barrier 4 on the end face 15 of stator body 1 at least covers stator line bag 2 and is contacted with end face 15 Region, further, the insulating barrier 4 on the end face 15 of stator body 1 is formed as annular (such as the institute of region I in Fig. 2 Show), the use of insulating materials thus can be reduced, reduce production cost.
Certainly, insulating barrier 4 can also be coated on the whole upper surface and lower surface of stator body 1, thus stator body 1 And the good insulating between stator line bag 2, stator 100 it is safe.
Alternatively, insulating barrier 4 can be coated on stator body 1 by Electrostatic Absorption mode, and the thickness of insulating barrier 4 can Think 0.02mm-0.5mm, such as thickness of insulating barrier 4 can be 0.05mm-0.3mm, so ensure stator body 1 and line Between circle and stator line bag 2 while good insulating properties, the use of insulating materials, reduces cost can be reduced.
Meanwhile, insulating barrier 4 can be the insulating barrier 4 with viscosity, and stator body 1 includes multiple stator punchings, so, many Individual stator punching can be integrally fixed by the insulating barrier 4 being formed on the inner surface of groove portion 12, so as to riveting parts can be avoided Use, mitigate the quality of stator 100, and the type of attachment of stator punching is simple.
As depicted in figs. 1 and 2, mounting hole 14 can be provided with stator body 1, mounting hole 14 can be four, four Respectively on four angles of stator body 1, so as to realize that stator 100 is fixed with the installation of rotor, and connection is firm for mounting hole 14 Lean on.
In sum, stator 100 according to embodiments of the present invention, by connecing in stator body 1 and enamel-cover linear contact lay Insulating barrier 4 is set in contacting surface, while the insulating requirements between enamel-covered wire and stator body 1 are met, it is possible to reduce to stator The space hold of groove portion 12, greatly improves the effective area of Stator Slots 12, while the usage amount of enamel-covered wire can be reduced, reduce around Group loss, lifting motor whole efficiency.
Present invention also offers a kind of motor, the motor includes above-mentioned stator 100, so as to have motor whole efficiency high The advantages of.
