<p>PROBLEM TO BE SOLVED: To provide a rotary electric machine coil capable of suppressing small a maximum potential difference between different-phase coils in a spiral coil end portion when forming the coil end portion.SOLUTION: A target concentric winding part 40a is a concentric winding part to be wound around a target slot 12a in which a coil side connectable to a connection terminal 90 is disposed. The target concentric winding part 40a is disposed so as not to include a concentric winding part of the same phase but is not the target concentric winding part 40a, in a circumferential direction between the target concentric winding part 40a and another target concentric winding part 40a of the same phase. An arrangement pattern of the target slot 12a of multiple phases is set to a pattern that minimizes variance in the circumferential direction C between target concentric winding parts 40a of phases different from each other and being adjacent in the circumferential direction C, among a plurality of arrangement patterns that make the order of arranging phases in the circumferential direction C for the target slot 12a of multiple phases equal to the order of arranging phases in the circumferential direction C for a slot 12 of multiple phases.</p> |
