Abstract

A rotary electric machine includes: a rotor; a shaft that penetrates the rotor along a rotation axis and is pivotally supported by a bearing; a stator accommodating the rotor inside; a rotor cover attached to an axial end surface of the rotor; and a casing having a flow passage for supplying oil to the bearing. The rotor cover has an oil receiving portion that forms a concentric clearance with respect to the shaft and receives the oil from the bearing in the clearance, and an oil distribution passage that communicates with the axial end surface of the rotor from the oil receiving portion. The rotary electric machine supplies the oil guided to the clearance to the oil distribution passage by centrifugal force to cool the rotor.
