Method for manufacturing a magnetic core of an electric vehicle motor
Abstract:
A method for manufacturing a magnetic core of an electric vehicle motor comprises: providing an electrical steel sheet and a release film; a heating step which heats the electrical steel sheet; an adhering step which adheres the release film to the heated electrical steel sheet; a removing step which removes the release film to leave the glue layer on the electrical steel sheet; a stacking step; a repeating step which repeats the heating step, the adhering step, the removing step and the stacking step to form a multi-layer structure having the electrical steel sheets and the glue layers interleaved stacked; and a solidifying step which heats the multi-layer structure to solidify the glue layers. Through the above steps, the thickness of the glue layer in the magnetic core would be uniform.
