Abstract

PURPOSE:To provide a high-speed rotary body having a simple structure wherein centripetal action is effected by use of a disc motor alone. CONSTITUTION:A rotary body 2 driven by a disc motor is centripetally supported by lower bearings 41, 42 and upper bearings 3. The disc motor comprises a disc rotor 51 and a stator 52, playing a conbined role of rotary and centripetal actions. Magnetic bearings air used for the upper bearing 3. The lower bearings comprise a bearing plate 41 and balls 42 for giving radially moving functions, and the lower structure being markedly simplified as compared to an apparatus using a magnet device for causing centripetal actions as the lower bearings.
