Abstract
In a rotary electric machine, a stator coil includes in-slot portions each contained in a corresponding one of slots of a stator core. The stator coil includes turn portions each connecting one end of a corresponding one of the in-slot portions projecting from one axial end of the stator core with one end of a corresponding alternative one of the in-slot portions projecting the one axial end of the stator core. The turn portions provide an end portion of the stator coil. A coolant guide is placed to cover a circumferential outer part of the end portion of the stator coil from radially outside thereof and provided with holes therethrough. The coolant guide guides a coolant therealong in a circumferential direction of the end portion of the stator coil while guiding, through the holes, a part of the coolant to the end portion of the stator coil.
