A high-speed electric machine (10), comprises a rotatably mounted rotor (11) which, separated by an air gap (14), is surrounded concentrically by a stator (12) with two winding overhangs (18,19), and comprises means (20, . . . ,29) for cooling the rotor (11) and stator (12), by means of which a cooling medium, especially cooling air, is sent on a circuit through the rotor (11) and the stator (12), and the heat picked up by the cooling medium or the cooling air in the process is extracted again in a cooler (20). In such a machine, improved and more cost-effecting cooling is achieved by the cooling medium or the cooling air being guided on two largely mutually independent, preferably parallel, first and second cooling circuits (24 and 25) for the stator (12) and the rotor (11).
