Abstract

PURPOSE:To make it possible to rotate in a floating state of a rotor as far as a superconductive state is maintained by cooling by a coolant by forming an incline providing the couple force to the rotor consisting of a floating superconductor in conjunction with the magnetism of a magnet. CONSTITUTION:When a rotor 1 previously have its temperature lowered to less than the critical temperature is put on a central axis of the permanent magnet 1 or the liquid nitrogen is supplied to the rotor 1 put on the central axis of the permanent magnet 5 from a liquid nitrogen supply device 3 to lower the temperature of the rotor 1 to less than the critical temperature, a radially repeated wavy incline is provided to the surface of the rotor 1, so the rotor 1 is floating over the permanent magnet 5, but, at the same time, the rotation starts to commence. The liquid nitrogen 2 is supplied from the liquid nitrogen supply device 3, and the rotor 1 continues to rotate in a state of floating as far as the rotor 1 is kept under the critical temperature.
