Abstract
A rotating electric machine includes a hollow cylindrical stator core and a stator coil mounted on the stator core. The stator core has a plurality of slots that are arranged in a circumferential direction of the stator core. The stator coil is formed of a plurality of substantially U-shaped electric conductor segments to include at least one Δ-Y connection. The Δ-Y connection includes a Δ-connected first three-phase winding and a Y-connected second three-phase winding. The first three-phase winding includes three phase windings that are Δ-connected to define three terminals of the first three-phase winding therebetween. The second three-phase winding includes three phase windings that are respectively connected to the three terminals of the first three-phase winding. Further, the number of turns of the first three-phase winding and the number of turns of the second three-phase winding are respectively set to two different odd numbers.
