Beschreibung
Zusammenfassung:	A rotary machine includes a rotary shaft equipped with an axial disc; an axial magnetic bearing which supports the rotary shaft; a motor which rotates the rotary shaft; a turbine impeller mounted on one end portion side of the rotary shaft; a compressor impeller mounted on the other end portion side of the rotary shaft; a cooling gas flow passage through which a cooling gas for cooling the motor flows; and a housing which accommodates at least the motor, the axial magnetic bearing, and the axial disc. The motor is equipped with a rotor unit provided on the rotary shaft, and a stator unit facing the rotor unit, the axial disc is equipped with a pair of load receiving surfaces sandwiched between the axial magnetic bearings, and the cooling gas flow passage is equipped with a first flow passage between the rotor unit and the stator unit, and a second flow passage extending along at least one of the load receiving surface.
