<p>PROBLEM TO BE SOLVED: To provide a rotary electric machine in which the number of jumper wire is reduced and circulating currents between circuits are suppressed even though armature wound wire has two poles and four parallel circuits.SOLUTION: Upper coils 2 at an inner diameter side and lower coils 3 at an outer diameter side of a slot are connected to form armature wound wire. The armature wound wire has 2n phase belts per phase, and the phase belts are made of two parallel wound wire. An average position in a circumference direction of all of the upper coils and the lower coils constituting the phase belts is set as a center of the phase belts. When arrangements of a first and a second parallel wound wire in at least one phase belt are viewed in order from the arrangement closest to the center of the phase belts, the upper coils or the lower coils are arranged in the order of a first, a second, the first, the second, the second, the first, the second, the first, the second, the first, the second and the first parallel wound wire and the other lower coils or the other upper coils connected to the above coils are arranged in the order of the first, the second, the first, the second, the first, the second, the second, the first, the second, the first, the second and the first parallel wound wire.</p> |
