Abstract:
Apparatus for supporting a rotor with respect to a stator comprisinga rotor having a plurality of closed rotor short-circuited loops each wound as a coil superconductive wire having zero electrical resistance at a temperature below a superconductivity transition temperature and each mounted on a shaft of the rotor in a plane perpendicular to an axis of the rotor, a stator enclosing the rotor and having a plurality of closed stator loops each wound as a coil of the superconductive wire and each spaced and mounted on the stator between ones of the rotor closed short-circuited loops so as to be off-center of the rotor axis,a cooling agent for cooling the closed rotor and stator closed loops to a temperature below the superconductivity transition temperature, and apparatus for energizing the cooled closed rotor and stator loops and establishing magnetic linkages therebetween forming a bearing supporting a rotation of the rotor in a stable equilibrium free state within the stator.
