Abstract:
Stator for rotary electric machine has stator core and stator coil. The stator core has plural slots. The stator coil has a one-side conductor segment, a first other-side conductor segment, and a second other-side conductor segment. In the one-side conductor segment, a first leg and a second leg are inserted in first and second slots from one axial end side of the stator core. In the first other-side conductor segment, a third leg is inserted in the first slot from another axial end side of the stator core. In the second other-side conductor segment, a fourth leg is inserted in the second slot from the other axial end side of the stator core. The stator coil is formed such that the opposing legs are joined in each of the slots and a plurality of the one-side conductor segment and a plurality of the other-side conductor segment are sequentially joined.
