Embodiment Construction

[0026] see in conjunction Figure 3 to Figure 5 As shown, according to an embodiment of the present application, a winding assembly includes:

[0027] There are multiple in-phase windings; all the in-phase winding groups are provided with a first set of windings and a second set of windings;

[0028] Both the first group of windings and the second group of windings include at least two adjacent same-phase windings;

[0029] All the same-phase windings in the first group of windings are wound by the first winding sequence, and all the same-phase windings in the second group of windings are wound by the second winding sequence; The first winding sequence and the second winding sequence are opposite winding directions.

[0030] The same-phase winding in this application refers to the winding formed by winding enameled wires of the same phase. In a stator or motor, the enameled wires of the same phase will be wound on multiple stator teeth at intervals. The windings wound in th...

Abstract

The invention provides a winding assembly, a stator assembly and a motor. The winding assembly comprises a plurality of in-phase windings, wherein all the in-phase windings are divided into a first group of windings and a second group of windings; each of the first group of windings and the second group of windings comprises at least two adjacent in-phase windings; all the in-phase windings in the first group of windings are formed by winding first winding wires in sequence, and all the in-phase windings in the second group of windings are formed by winding second winding wires in sequence; and the first winding sequence and the second winding sequence are opposite in winding direction. According to the winding assembly, the in-phase windings are grouped, and the winding directions of each group are set oppositely, so that the winding mode of the in-phase windings is changed, and the number of cross slots of the bridging wires of the in-phase windings is greatly reduced, so that the bridging wires can be shortened, the copper consumption at the bridging wires is reduced, the wiring operation is simpler, and the working efficiency is improved.

Description

technical field [0001] The application belongs to the technical field of motors, and in particular relates to a winding assembly, a stator assembly and a motor. Background technique [0002] At present, the existing stator structure includes a stator core, a skeleton, and a stator winding. Several teeth protrude from the side wall of the stator core, and a wire groove is formed between two adjacent teeth. The stator winding is embedded in the wire groove and Wound on the teeth, there are various winding methods and wiring methods of the stator winding, among which the most conventional two-way parallel connection winding method starts from the starting point of the winding, and the winding direction of all the teeth is the same, clockwise or counterclockwise; such as figure 1 with 2 As shown, the winding wire head of each phase winding of the stator is combined with the diagonal phase wire head in parallel and is the input end of the phase winding, and the winding wire tai...
