Embodiment 1

[0062] In this example, if Figure 1-Figure 9 As shown, the motor includes an iron core 1 and a winding. The iron core 1 can be roughly formed into a closed circular ring structure, and the iron core 1 includes 12 segmented iron cores 11 arranged in sequence along the circumferential direction. Each segmented iron core The core 11 includes a yoke portion 111 and a tooth portion 112 connected radially along the iron core 1, and an iron core slot 110 is formed between two adjacent tooth portions 112. In the circumferential direction of the iron core 1, each segmented iron core 11 The width of the yoke portion 111 is larger than that of the corresponding tooth portion 112 , and the winding is placed in the core slot 110 and wound on the tooth portion 112 of each segmented iron core 11 . Wherein, the rotor of the motor is located inside the stator, the iron core 1 is a stator iron core, and the outer peripheral wall of the iron core 1 is formed in a circular shape.

Embodiment 2

[0070] Such as Figure 10 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1, wherein the same components use the same reference numerals, the difference is that when the iron core 1 is in the unfolded state, the seven segmented iron cores 11 are distributed in a straight line 1. The five segmented iron cores 11 are distributed in an arc shape, and the iron core slots 110 between the five segmented iron cores 11 are set outward.

Embodiment 3

[0072] Such as Figure 11 As shown, the structure of this embodiment is substantially the same as that of Embodiment 2, wherein the same components use the same reference numerals, the difference is that when the iron core 1 is in the unfolded state, the nine segmented iron cores 11 are distributed in a straight line , The three segmented iron cores 11 are distributed in an arc shape, and the iron core slots 110 between the three segmented iron cores 11 are set outward.

Abstract

The invention discloses a manufacturing method of a motor. The motor comprises an iron core and a winding, wherein the iron core comprises a plurality of blocked iron cores which are sequentially arranged along a circumferential direction in an end-to-end way, and the winding is arranged in an iron core groove and is wound around a tooth part of each blocked iron core. The manufacturing method ofthe motor comprises the following steps of arranging a plurality of detachable auxiliary tools at outer sides of the plurality of blocked iron cores in one-to-one correspondence, wherein two adjacentauxiliary tools can be pivotally connected; rotating the plurality of auxiliary tools so that the iron cores are in unfolded states; performing winding on each blocked iron core to form the winding; and rotating the plurality of auxiliary tools so that the iron cores are switched to be in closed states, wherein the iron cores are of annular structures when the iron cores are in closed states. Themanufacturing method of the motor is simple in process and is convenient to implement, the disassembly and the assembly of the blocked iron cores are facilitated, and the manufacturing cost of the motor is reduced.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a manufacturing method of a motor. Background technique [0002] Segmented iron core is a commonly used stator core structure, which can increase the slot fill rate and improve winding efficiency, and is widely used in home appliances such as fans and air-conditioning compressors. Among them, the assembly and splicing of the segmented iron core is more troublesome, and there are many manufacturing steps. In order to solve the above problems, a hinged iron core is used in the related art. However, the manufacture of the hinged iron core is relatively difficult, the manufacturing cost is high, and the manufacturing efficiency is low. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a motor manufacturing method, which is simple in process ...
