Abstract
A magnetic levitation bearing, a magnetic levitation rotor support assembly, and a compressor. The magnetic levitation bearing is used for supporting a rotor by interacting with a thrust disc on the rotor, and comprises: a radial stator core having an annular structure, which is disposed on a radial outer side of the thrust disc and corresponds to the thrust disc in an axial direction of the rotor, the radial stator core and the thrust disc being separated by a first radial gap X; and a radial control coil, which is disposed on the radial stator core and can generate a radial electromagnetic force to the thrust disc in a radial direction of the rotor.
