Description

[0002] The motor stator skeleton is a key component of a motor stator, which not only plays a role in fixing and positioning coils, but also is a core element for controlling electromagnetic field distribution. A skeleton of the prior art is composed of multiple skeleton groups, the multiple skeleton groups are uniformly distributed along the axial direction of the stator, and each group contains two skeletons. Each skeleton is wound by a coil made of copper material.

[0003] In the winding process, two parts of each skeleton need to be wound by a copper wire respectively. After a copper wire completes the winding of two skeletons, it needs to be bent so as to make the side edges of the two skeletons close to each other and form a compact structure.

In order to avoid the copper wire from being broken during the bending process, the worker must control the speed of moving the skeletons, which not only reduces the working efficiency of bending the copper wire, but also makes the manually bent copper wire not regular and beautiful enough.
