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.

The invention discloses a motor and a grounding wire component mounting structure thereof. The grounding wire component mounting structure of the motor comprises a main case, a support plate and a grounding wire component, wherein the support plate is arranged on the outer wall surface of the main case, and screw mounting holes are formed in the support plate; through holes are formed in the grounding wire component, and the grounding wire component is mounted on the support plate through screws which penetrate through the through holes and are matched in the screw mounting holes. The grounding wire component mounting structure of the motor has the advantages that the screws do not easily loose, connection is reliable, and the ratio of interturn short-circuit and the defective rate of stators can be reduced.
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...
