摘要:
The electric rotating machine includes a rotor relatable around a rotating shaft disposed horizontally, a stator core formed with slots, and a stator coil constituted of in-slot portions each of which is accommodated in a corresponding one of the slots, and turn portions each of which connects corresponding adjacent two of the in-slot portions at a position outside the stator core. The turn portions form a coil end projecting axially outward from an end surface of the stator core at each of both axial end sides of the stator core. The coil end is formed in a cylindrical shape including an axial end surface of a flat shape, and inner and outer peripheral surfaces of a circular shape. The electric rotating machine further includes a coolant supply section to supply coolant to an upper part of the outer peripheral surface of the coil end.
