PROBLEM TO BE SOLVED: To endure mechanical stress and thermal stress, which a rotor or a stator receives during building-up and during operation, by preparing a sufficient thermal barrier between a superconductive magnetic field coil and a mounting stage for magnetic field coil support structure. SOLUTION: The rotor 1 for a superconductive electrical machine includes a mounting stage 2 substantially maintained at an environment temperature during operation of the electrical machine, and a magnetic field coil support structure 3. Two or more superconductive magnetic field coils 4 are maintained at an ultra-low temperature during operation of the electrical machine and are supported by magnetic field coil support structure 3. At least one coupling component 5 is used for fixing the magnetic field coil support structure 3 to the mounting stage 2. In order to separate the mounting stage and the magnetic field coil support structure firmly by a vacuum gap along the axial directional length, the magnetic field coil support structure 3 is preferably fixed to the mounting stage 2 at a first axial edge portion and a second axial edge portion of the magnetic field coil support structure and the mounting stage by using two or more coupling components 5 extending substantially in circumference direction.
