Abstract
A rotating electric machine includes a rotor, a stator, a cooling device and a pair of cooling liquid collection tanks. The stator includes an annular stator core and a stator coil. The stator core is disposed radially outside the rotor so as to surround the rotor. The stator coil is mounted on the stator core so that a pair of coil ends of the stator coil protrude axially outward respectively from opposite axial end faces of the stator core. The cooling device is configured to supply cooling liquid to vertically upper parts of the coil ends of the stator coil. Each of the cooling liquid collection tanks is arranged to surround a vertically lower part of a corresponding one of the coil ends so as to collect and temporarily reserve therein the cooling liquid moved from the upper part to the lower part of the corresponding coil end.
