<p>PROBLEM TO BE SOLVED: To obtain a rotary electric machine comprising a stator in a winding wire structure in which options for the number of serial turns can be enlarged.SOLUTION: In a coil, N pieces of lead wires which are wave winding wires divided in two or more locations in a circumferential direction are put into one slot. Within a unit to be conducted by the divided wave winding wire, the lead wires are connected in series or in parallel in the almost same dividing location in the circumferential direction of a lead wire end portion. In each of phases, divided units of the divided wave winding wires mounting in partial slots in slots of an entire rotary electric machine and partial slots different from each other are connected in series with each other. The number of total serial turns of the divided units connected in series in each phase is the predetermined number of serial turns which does not exceed a terminal voltage upper limit value of the rotary electric machine. The numbers of total serial turns of the divided units connected in series in the phases are equal to each other and within a unit conducted by the divided wave winding wire, in the almost same division location in the circumferential direction of the lead wire end portion, all the lead wires are connected in series.</p> |
