Abstract

The invention provides a connecting structure for a control panel, a motor control panel, a stator assembly and a motor, relates to the technical field of motors, and solves the technical problems inthe prior art that the motor control panel and the stator assembly are soldered by tin soldering, so that the production efficiency is low, and the soldering process is harmful to human body. The connecting structure for the control panel comprises matching pins and inserting pins, one of the matching pins and the inserting pins are arranged on the motor control panel, and the other one are arranged on the stator assembly. When all the inserting pins make contact with the corresponding matching pins respectively, the electric connection between the motor control panel and the stator assembly can be achieved. According to the present invention, the quick connection between the motor control panel and the stator assembly is realized.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a connection structure for a control board, a motor control board, a stator assembly and a motor. Background technique [0002] In existing brushless DC motors with a plastic-encapsulated structure, the motor control board is either included in the stator assembly and injection-molded together with the stator assembly; or placed between the end cover and the stator assembly after the injection molding of the stator assembly is completed. For the former, since the motor control board will be under pressure during the injection molding process, there are hidden dangers of damage and failure, and the scrap rate is high; for the latter, after the injection molding of the stator assembly is completed, the motor control board is placed on the stator assembly, and U, The V and W three-phase pad holes need to be matched with the three-phase terminals of the stator assembly and welded sepa...
