Description

Technical Field

[0001] The utility model relates to a stator lead-out line clamping tool. Background Art

[0002] At present, the stator in the motor includes a stator core and a stator winding. The stator winding can be formed by winding a flat wire. After the stator winding is completed, the lead wire on the stator winding needs to be twisted and formed to be twisted into a desired shape. In order to improve the quality of the lead wire twisting and forming, it is necessary to fix the root of the lead wire during the twisting process.
