Abstract: A rotating electric machine includes a rotor, a stator, formed by stacking perforated-disk-shape stator cores, surrounding the rotor, arranged with a gap from the rotor, a first stator cooling duct to allow the cooling gas to flow from an inner side toward outer side of the stator, a second stator cooling duct to allow the cooling gas to flow from an outer side to an inner side of the stator, a plurality of support plates for supporting the stator and providing sectioning between the first and second flow paths, and a flow control part configured to suppress a flow of the cooling gas passing through the gap part where the outer end part of the stator core and the inner end part of the support plate face each other.

Abstract: A channel connecting a first opening formed on one side surface of a rotor and a second opening formed on the other side surface of the rotor is provided, and a first distance from a rotating shaft to the center of the first opening and a second distance from the rotating shaft to the center of the second opening are differentiated. A differential pressure is generated between the first opening and the second opening provided in the rotor by the differentiating the distances from the center of the rotating shaft to the first opening and the second opening, a flow of air is generated by the differential pressure from one surface or the other surface of the rotor to the other surface or the one surface, whereby the stator in proximity to the rotor may be cooled.
