Abstract

The invention discloses a radially decoupling hybrid magnetic bearing, comprising: a mounting seat, a stator system and a rotor system, the mounting seat is configured with an installation space; the stator system is arranged in the installation space, and comprises a first stator iron core, a stator The magnetic isolation sleeve, the first permanent magnet, the second stator core, the second permanent magnet and the stator magnetic isolation ring, the first stator winding and the second stator winding are respectively wound on the first stator core and the second stator core, wherein A rotor installation cavity is enclosed between the first stator winding, the second stator winding and the second stator iron core; the rotor system is accommodated in the installation cavity. The hybrid magnetic bearing of the present invention eliminates the bias current, reduces the power consumption of the magnetic bearing, and at the same time can realize radial two-degree-of-freedom control, thereby effectively improving the high-precision translation control of the rotor.

Description

technical field [0001] The invention relates to the technical field of non-contact magnetic suspension bearings, in particular to a radial decoupling hybrid magnetic bearing. Background technique [0002] Compared with traditional medium and low-speed motors, high-speed motors have the advantages of high speed and high power density. They can be directly connected to high-speed loads, eliminating the need for traditional mechanical gear speed-up devices. The energy-saving effect is remarkable, and they are widely used in blowers and compressors. , machine tool spindles and other high-speed occasions, the market prospect is broad. The support bearings commonly used in high-speed motors include mechanical bearings, oil film bearings, air bearings and magnetic suspension bearings. Mechanical bearings are limited by contact friction and wear and cannot work for a long time; oil film bearings require a special oil circulation system with complex structures and frequent leakage. ...
