Title:
MAGNETIC LEVITATION BEARING, MAGNETIC LEVITATION ROTOR SUPPORT ASSEMBLY, AND COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/119973
Kind Code:
A1
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 acting with a thrust disc (2) on the rotor, and comprises: a radial stator iron core (5) in an annular structure which is provided on the radial outer side of the thrust disc (2) and corresponds to the thrust disc (2) in an axial direction of the rotor, the radial stator iron core (5) and the thrust disc (2) being separated by a first radial gap X1; and a radial control coil (4) which is provided on the radial stator iron core (5) and can generate radial electromagnetic force to the thrust disc (2) in a radial direction of the rotor. The magnetic levitation bearing can generate controllable radial electromagnetic force to the thrust disc in a radial direction of the rotor, and therefore, higher flexibility of the bearing can be designed, and the application range of the bearing can be effectively widened.
