PURPOSE:To prevent the shaft vibration without generating any heating and braking torques with the repulsion force of Meissner effect located between the plate made of a superconducting body which is fixed to a rotary shaft and the magnet set fixed to a housing by opposing to these both faces. CONSTITUTION:Plates 3, 4 made of superconducting bodies are fixed vertically to a rotary shaft 2 thereto, the respective both faces are opposed and the magnets 5a-5c, 6a-6c and 7a-7c forming the magnetic field in the thickness directions of the plates 3, 4 or in the reverse direction each other are fixed to a housing 1. Consequently a noncontact support is executed with the repulsion force caused by a Meissner effect, the generation of heating and braking torques by an eddy current is eliminated, the rotary state is stabilized and a shaft vibration can be restrained. |
