Abstract

PURPOSE:To shorten the size in an axial direction as well as to eliminate rotational oscillations to enhance the density of magnetic flux by forming pneumatic bearings in spaces between the outer face of a cylinder of a rotor element and the inner face thereof and between opposing faces perpendicular to the axial direction provided thereon. CONSTITUTION:A cylindrical rotor element 14 is fixed on a rotary shaft 12, on the periphery of the outer face 14a thereof a stator element 16 is provided through a gap 34, and an end-plate-shaped thin plate members 18a, 18b are fixed on both ends thereof. Compressed air is introduced into air flow passages 24, 26, 28, annular deep grooves 30, 32, shallow grooves 38, 40, and a gap 34 from an air inlet 22 and discharged from an air flow passage 36. Thrust and radial pneumatic bearings are thus formed respectively by groove passages 38, 40 and the gap 34. it is therefore possible to dispensed with any rolling bearing so as to shorten the size in the axial direction as well as to shut off rotational oscillations, and shorten the gaps 34 between the elements 14, 16 so as to enhance the density of magnetic flux.
