【 摘 要 】

Paper describes design and testing of the 200 kW synchronous motor with 2G HTS field coils. The superconductivity motor with two different temperature conditions of the stator and the rotor was designed and initially tested. This decision was dictated by the need to ensure high rotation speed. Design with the fully submersible cryo-rotor, in this case, was not justified because of the large friction losses in liquid nitrogen. So, more complex construction of the rotor with rotating cryostat based on super-insulation was used. A special rotating inlet pipeline for the transportation of nitrogen liquid in the location of the HTS coils was developed.
