PURPOSE: A hybrid thrust magnetic bearing is provided to minimize the diameter of an axial direction disc and produce bias magnetic flux to a permanent magnet without unstable power in a disc radial direction. CONSTITUTION: A hybrid thrust magnetic bearing comprises a mover(110), a stator(120), and coils(130,140). The mover comprises thrust discs(111,112) and a permanent magnet(113). The thrust disc is extended from the rotary shaft of the rotation apparatus in the radial direction. The stator comprises multiple cores(121,122,123) and a main body(124) connecting the multiple cores. The coil is wound between the multiple cores. |
