Abstract
A motor generator serving as a rotating electric machine includes: a rotor; a rotor shaft rotating with the rotor; and end plates and provided at opposite ends, respectively, of the rotor. The rotor shaft has oil channels and provided independently of each other and passing oil therethrough. The end plates and have oil channels and communicating with the oil channels and, respectively, and guiding oil to the rotor. The oil channels and are formed so as to avoid passing oil in a stream having vector components facing one another, as seen in the axial direction of a center axis, on the route of the channels. The oil channels and are formed so as to avoid passing oil in a stream having vector components facing one another, as seen in the axial direction of the center axis, on the route of the channels. The rotating electric machine thus allows the rotor to be cooled uniformly.
