Problems solved by technology

[0002] In the motor in the related art, the grounding wire assembly is installed on the casing by screws. Since the casing is thin, the matching length between the screw and the screw hole on the casing is small, which is easy to slip and has poor reliability.
In addition, the screws protrude into the casing. In order to ensure a safe electrical clearance, the end of the stator needs to be processed very short, resulting in over-shaping of the end of the stator, resulting in a large proportion of inter-turn short circuits and a high rate of defective stators.

Abstract

The invention discloses an installation structure of a motor and its ground wire assembly. The installation structure of the ground wire assembly of the motor comprises: a casing; There are screw mounting holes on the board; the grounding wire assembly is provided with a through hole, and the grounding wire assembly is installed on the Support board. The installation structure of the grounding wire assembly of the motor according to the embodiment of the present invention has the advantages of not easy to slip teeth, reliable connection, capable of reducing inter-turn short circuit ratio and stator defective rate, and the like.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a motor ground wire assembly installation structure and a motor having the motor ground wire assembly installation structure. Background technique [0002] In the motor in the related art, the grounding wire assembly is mounted on the casing by screws. Since the casing is thin, the matching length between the screw and the screw hole on the casing is small, and the teeth are easy to slip and the reliability is poor. In addition, the screws protrude into the casing. In order to ensure a safe electrical clearance, the end of the stator needs to be processed very short, resulting in over-shaping of the end of the stator, resulting in a large proportion of inter-turn short circuits and a high rate of defective stators. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a cer...
