The invention discloses an embedded electromagnetic-elastic foil gas mixing bearing, which comprises an electromagnetic bearing arranged in a bearing base, wherein the electromagnetic bearing is provided with a left end cover and a right end cover in an axial direction, an elastic foil bearing is embedded and sleeved between the left and right end covers and a rotor journal, the electromagnetic bearing is provided with a magnetic pole which has a coil, the left and right end covers are arranged in a branch opening at the root of the magnetic pole to form a bearing base of a foil bearing; and the bearing base of the oil bearing is provided with a groove, a top elastic foil and a bottom elastic foil are inserted into the groove, and when the coil is switched on, an electromagnetic field is formed between a pole shoe of the magnetic pole and the rotor journal, so that the pole shoe attracts the rotor journal. At a low speed, a rotor is supported by the electromagnetic bearing; when the rotating speed reaches a certain value, a gas film between the top foil and the journal generates a dynamic pressure; and at a high speed, the rotor is individually supported. The embedded electromagnetic-elastic foil gas mixing bearing has the characteristics of low power consumption, high precision, high bearing capability and compact structure.
