Method for manufacturing stator Coyle and stator Coyle and rotary electric machine having stator Coyle

摘要

Problem to be solved: to provide a stator Coyle for preventing the removal of an insulating varnish impregnated in a junction portion of a stator Coyle, a method of manufacturing the stator Coyle, and a rotary electric machine having a stator.Solution: a junction portion 20 to which the Coyle conductor 1 is welded to the end 50 of the Coyle is provided, and the exposed part 1a is provided from the end face 1b of the parasitic conductor 1 to the first predetermined distance L1, and the first depression 4a is at the end of the exposed part A second depression 4b is provided at a second predetermined distance L2 longer than the first predetermined distance L1 from the end face 1b, and an insulating varnish 5 is impregnated in the end portion 50.Diagram
