PROBLEM TO BE SOLVED: To provide, as a stator coil of a rotary electric machine, a stator coil configured such that insulation characteristics of a crank part provided at a swollen part of a coil end part are prevented from decreasing in a process of forming the coil end part.SOLUTION: Of a coil end part 120 connecting a linear part 7C of a stator coil 11 inserted into a slot of an iron core 10 of a stator, a hypotenuse part 7D is provided with a swollen part 7A, and a curvature-reduced part 110C is provided which is formed at a predetermined distance from both sides of a crank part 110 formed at the swollen part 7A.SELECTED DRAWING: Figure 5 |
