A rotor for an electric machine includes a pole core having a coolable magnetisable rotor section which is made of a super-conducting material. The rotor section has a rotationally symmetric geometry. The pole core is formed as a cylinder and the rotor section is arranged on an outer surface of the cylinder so as to be encircling.
