ABSTRACT:
A rotor shaft provided with a fan is rotatably supported by pneumatic bearings for the purpose of high speed rotation with low noise. The rotor shaft provided with the fan can also be supported at one end by a resilient bearing so as to provide high speed rotation even if the concentricity of the bearings is low.
