The invention describes a rotor (17) of an electrical machine (13) having a first housing (1) and a second housing (2), which is arranged in the interior of the first housing (1) with a cavity (18) with respect to the first housing (1). A liquid cryogen (9) can be introduced into the second housing (2) through a first opening (4) formed on the second housing (2). The vaporised cryogen (10) can be introduced into the cavity (18) through a second opening (5) formed on the second housing (2). The vaporised cryogen (10) can flow out from the cavity (18) through a third opening (6) formed on the first housing (1). In addition, the invention describes an electrical machine (13), a device for cooling and an aircraft. The invention also relates to an associated method for cooling a rotor (17).
