STATOR OF ROTARY ELECTRIC MACHINE

摘要

A stator of a rotary electric machine includes a stator core that includes a plurality of slots; and a plurality of conductor segment coils that each have a U-shape. A sectional area of the U-shaped portion of the conductor segment coil that protrudes out from one side in the axial direction of the stator core is larger than a sectional area of a tip end portion of the conductor segment coil that protrudes out from the other side in the axial direction of the stator core; and the sectional area of the tip end portion of the conductor segment coil that protrudes out from the other side in the axial direction of the stator core is larger than a sectional area of an in-slot portion of the conductor segment coil.
