The invention relates to a superconductive synchronous electric motor to be applied in the field of electric power drives, in the power machine building industry, in the industry for electric transport and naval transport means. According to the invention, the motor consists of an outer cylindrical enclosure (1) accommodating therein another rotor cylindrical enclosure (2) and a three-phase stator winding (4), the space therebetween being vacuumed to a minimum pressure of 10torr, the rotor enclosure (2) rotating about its own symmetry axis by means of a rotor shaft (5) and it is supplied with cryogenic agent by a cryogenic cooling system (7), the rotor enclosure (2) containing the support of some superconductive coils (3, 9) generating an intense magnetic field and which are cooled by the cryogenic agent through some access openings (11), the cryogenic agent outlet being ensured through some discharge orifices (13) and through a clearance between an access pipe (10) and the rotor shaft (5), returning to the cooling cryogenic system (7). |
