Embodiment Construction

[0019] see figure 1 , a method for processing a motor stator core provided by an embodiment of the present invention includes:

[0020] Step S1, dipping and dripping paint on a plurality of electrical steel laminations.

[0021] Step S2, performing hot pressing on a plurality of electrical steel laminations to obtain electrical steel laminations.

[0022] Step S3, drilling and wire-cutting the electrical steel stack to obtain the stator core block.

[0023] Step S4, performing laser welding on the stator core block to obtain the stator core.

[0024] Specific Embodiments of the Application Due to the dipping and dripping of multiple electrical steel laminations, a paint film is formed on the surface of the electrical steel laminations to protect the electrical steel laminations, avoid corrosion, and ensure the performance of the motor stator core , because multiple electrical steel laminations are hot-pressed to obtain electrical steel lamination blocks, so there is no need...

Abstract

The invention discloses a machining method of a motor stator core, and belongs to the technical field of motors. The machining method of the motor stator iron core comprises the following steps: carrying out paint dipping and paint dripping on a plurality of electrical steel laminations; carrying out hot pressing on the plurality of electrical steel laminations to obtain an electrical steel laminated block; punching and linear cutting are carried out on the electrical steel laminated block to obtain a stator iron core block; and performing laser welding on the stator iron core block to obtain the stator iron core. According to the machining method of the motor stator core, corrosion can be avoided, and the performance of the stator core is ensured.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a processing method for a stator core of a motor. Background technique [0002] In the motor research and development stage, and when using ultra-thin silicon steel sheets with a thickness of less than 0.1mm to produce motor cores, it is usually necessary to use wire cutting to process motor stator cores. However, the conventional wire-cutting process for motor stator cores usually uses electrical steel laminations to be welded at the edge or clamped by tooling fixtures for wire-cutting processing; then the processed motor stator pieces are cleaned and wiped one by one; The finished lamination tooling is used for sorting and lamination, and then the motor stator laminations are tightened with bolt locks with the lamination tooling; and then the laminated motor stator laminations are welded with an argon arc welding machine. [0003] However, due to the conventional processing tec...
