Pure oil-free air suspension compressor based on horizontal shaft magnetic suspension

The invention relates to the technical field of air compressors, and discloses a pure oil-free air suspension compressor based on horizontal shaft magnetic suspension. The compressor comprises a shell fixed to an external environment, a stator fixedly arranged in the shell through a clamping groove, a rotor movably arranged in the center of the stator, a central suspension rotating shaft penetrating through the center of the rotor, and a suspension unit arranged in the shell and used for enabling the central suspension rotating shaft to suspend; and the suspension unit comprises two composite suspension bearings which are arranged on two sides of the stator correspondingly and are movably connected with the central suspension rotating shaft. The compressor not only can solve the problems of complex control and high manufacturing cost of the magnetic suspension bearing, but also can greatly improve the bearing capacity of the air suspension bearing, and solves the problem of weak impact resistance of the air s
