<P>PROBLEM TO BE SOLVED: To provide an armature coil which is applied to a large capacity rotating electric machine having three-phase two-pole 72 slots having six parallel circuits. <P>SOLUTION: In the armature coil that is fitted into 72 slots, each of the phases has six parallel circuits that are divided into two phase belts; each of the parallel circuits consists of two coil pieces, an upper coil piece 15 and a lower coil piece 16, which are mutually and serially connected at the connecting-side coil end and the non-connecting-side coil end. The upper coil pieces of the first and fourth parallel circuits are connected, when indicating the relative positions of the upper and lower coils within one phase belt as positions counted sequentially from the pole center, to the third, fourth, seventh and twelfth positions from the pole center, and the lower coil pieces are connected to the first, sixth, ninth and tenth positions from the pole center; the upper and lower coil pieces of the second and fifth parallel circuits are connected to the fifth, eighth and eleventh positions from the pole center; the upper coil pieces of the third and sixth parallel circuits are connected to the first, sixth, ninth and tenth positions from the pole center, and the lower coil pieces are connected to the third, fourth, seventh and twelfth positions from the pole center. <P>COPYRIGHT: (C)2011,JPO&INPIT |
