Description

Technical Field

[0001] The utility model relates to a tool, in particular to a flat wire paint removal tool for motors. Background Art

[0002] As automotive drive motors develop towards high performance, high efficiency and high power density, flat wire motors have been gradually applied to new energy vehicles due to their high slot fill rate and good NVH characteristics.

[0003] Since the thickness and rigidity of the flat wire are different from those of ordinary copper wire, it must first be bent into a certain shape and then installed into the stator slot, and then the welding process can be carried out. Before welding, the paint on both ends of the flat wire needs to be removed.

[0004] In the prior art, paint is generally removed from a flat wire by a scraper. However, the position of the scraper is fixed in the prior art, and the flat wire is moving. Due to the different thicknesses and completeness of the flat wire itself, the fixed scraper may not completely remove the paint when removing the paint. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a suggested tooling, so that the flat wire can be pulled, so that the paint on its surface can be removed.

[0006] The technical solution of the utility model is as follows:
