<p>PROBLEM TO BE SOLVED: To provide a stator and a rotary electric machine capable of diversifying wire-connection variation by restraining a potential difference between coils.SOLUTION: In a stator, a slot is formed to house a conductor 16 in a laminate manner from one side to the other side in a radial direction, and coils 161, 162 have slot housing parts housed in different slots, and turn parts projecting from the slot housing parts. The coils 161, 162 are constituted so that two layers, a 2n-1-th layer and a 2n-th layer are wound around a stator 12 and the coils 161, 162 of the 2n layer are connected to the coils 161, 162 of a 2n+1-th layer. According to this constitution, the coils 161, 162 are respectively wound twice, so as to electrically connect the coil 161 of a second layer and the coil 162 of a third layer. All of the coils 161, 162 have the identical length, and therefore, a potential difference between the coils 161, 162 becomes small. The coils 161, 162 can be arbitrarily connected to each other, so as to diversify wire-connection variation.</p> |
