Abstract

A rotor core of a rotating electric machine includes a cooling passage. The cooling passage includes an upstream end that opens in a first end surface of the rotor core and a downstream end that opens in a second end surface of the rotor core. The rotating electric machine is further equipped with a rectifying structure for converting the flow direction of gas an axial direction and a circumferential direction of the rotor. The rectifying structure is fixed to a non-rotating portion in a casing so as to face a rotor in an axial direction.
