摘要
The present invention relates to an electromagnetic enable dynamic pressure gas bearing comprising an electromagnetic bearing (1) and an elastic foil bearing (3) enclosed between an electromagnetic bearing (1) and a rotor shaft (2), characterized in that said elastic foil bearing 3 includes an upper layer elastic foil 31 and a lower layer elastic foil 32. The upper layer elastic foil 31 is a nonmagnetic material and a plurality of independent magnetic material regions are formed on the surface of the upper layer elastic foil 31 The present invention also provides an electromagnetic inertia dynamic pressure gas bearing. The electromagnetic interference active type gas bearing of the present invention has a simple structure, a low requirement for precision, a structure of a gas-magnetic coupling bearing, an adjustable magnetic flat foil and a low-cost pressure sensor, The low speed bearing force existing in the operation of the gas bearing is low and the controllability due to the leakage of the lubricating air due to the eccentricity due to the bearing perturbation is solved.
