Embodiment Construction
[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0048] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom...) in the embodiments of the present invention are only used to explain As shown in the figure), if the relative positional relationship between the various components, etc., if the specific posture changes, the directional indication will also change accordingly.
[0049] It should also be noted that when an element is referred to as being “fixed” or “disposed on” another element, the element may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0050] see Figure 1 to Figure 9 , the embodiment of the present inve...

The invention provides a winding method of a stator, the stator and a micro water pump. The stator comprises an iron core and a winding; the iron core comprises a yoke part and a plurality of tooth parts surrounding the yoke part, the plurality of tooth parts are divided into at least two groups, and the winding method comprises the following steps: providing an auxiliary part, wherein the auxiliary part comprises a wire hanging part; winding a wire on one group of tooth parts to form a one-phase winding; after one phase of winding is formed, enabling a wire to bypass the wire hanging part andbe wound on the other group of tooth parts, and forming the other phase of winding. According to the winding method of the stator provided by the invention, the two-phase winding can be in a tightened state, the winding is not loosened, and a winding post arranged on the yoke part in the existing scheme can be canceled, so that the thickness of the iron core can be reduced, the small-size designis facilitated, meanwhile, parts are reduced, and the cost is reduced.
Description
【Technical field】 [0001] The invention relates to the technical field of electric equipment, in particular to a stator winding method, a stator and a micro water pump. 【Background technique】 [0002] The stator is a common driving component, whose main function is to generate a rotating magnetic field, and drive the rotor to rotate through the principle of electromagnetic induction to output rotational motion. A common stator includes an iron core and a winding. The iron core includes a yoke and a plurality of teeth surrounding the yoke, and the winding is wound on the teeth. For two-phase and more than two-phase stators, the upper or lower surface of the yoke is usually equipped with winding posts. After winding one phase winding, the wire can be wound several times on the winding posts before winding another winding post. One-phase winding, so that the winding will not be loose. However, arranging the winding post on the upper surface or the lower surface of the yoke res...
