A coil structure for a rotary electric machine includes phase coils for magnetic flux generation. Each of the phase coils includes a plurality of first element conductors, a plurality of second element conductors, a plurality of first crossover portions, and a plurality of second crossover portions. The plurality of second element conductors are provided in a plurality of second slots among slots. The second slots are provided in a circumferential direction of a stator at a pitch of a first predetermined interval. The second slots are shifted in phase by a second predetermined interval with respect to first slots in the circumferential direction of the stator. The first predetermined interval is set to be an interval equivalent to N times a unit pitch. The second predetermined interval is set to be an interval smaller than the first predetermined interval.

Coil structure for rotary electric machine

A rotary electric machine includes a three-phase coil including a first phase coil, a second phase coil, and a third phase coil for magnetic flux generation. A bridge conductor connecting an ath end and a bth end of the first phase coil, and a bridge conductor connecting the ath end and the bth end of the third phase coil are provided in a protruding shape on one side of a stator in a radial direction when viewed in a axial direction of the stator. A bridge conductor connecting the ath end and the bth end of the second phase coil is provided in a protruding shape on the other side of the stator in the radial direction when viewed in the axial direction of the stator. The bridge conductor of each coil in the three-phase coil is arranged at the same height position in the axial direction.

Rotary electric machine

In a stator constituting a rotary electric machine, a U-shaped first and second divided conductors are disposed at slots. The pitch of a pair of straight parts of the first divided conductor is set larger than that of a pair of straight parts of the second divided conductor. The second divided conductor is disposed on the inner side of the first divided conductor, more specifically, on the stator core side.
