Patent number: 9181979Abstract: A hybrid type permanent magnet bearing system which utilizes four permanent magnet rings to replace the mechanical bearings. These rings are divided into two separated groups along an axis, where each group has an inner ring and a separated outer ring. At least one permanent magnet ring has a surface facing the gap between the two groups but being not vertical to the axis. Hence, inside the gap, the magnetic field between these permanent magnet rings is not non-uniform over different directions, and then it may behave as the axial and radical bearing simultaneously.Type: GrantFiled: June 26, 2012Date of Patent: November 10, 2015Assignee: CHUNG YUAN CHRISTIAN UNIVERSITYInventors: Yi-Hua Fan, Ying-Tsun Lee, Chung-Chun Wang, Yi-Lin Liao

Patent number: 9163666Abstract: An axial passive magnet bearing system utilizes the friction-less characteristic of non-contact type permanent magnet bearing to minimize the disadvantages induced by frictions. For example, both the energy and material loses of the mechanical bearing. Two permanents magnet are made of permanent magnet materials and positioned over two opposite surfaces of two mechanical structures, where mechanical bearing(s) is located therebetween. Hence, the magnetic force between the two magnets can improve some disadvantages among the two mechanical structures and the mechanical bearings, such as friction and energy loss.Type: GrantFiled: June 15, 2012Date of Patent: October 20, 2015Assignee: CHUNG YUAN CHRISTIAN UNIVERSITYInventors: Yi-Hua Fan, Ying-Tsun Lee, Chung-Chun Wang, Yi-Lin Liao

Patent number: 9059610Abstract: An axial hybrid magnetic bearing (HMB) is disclosed herein. The HMB has a first electric magnet, a second electric magnet, and a rotor being between the two electric magnets. The rotor has a permanent magnet (PM) structure facing the two electric magnets by its two sides. By doing so, the power consumption can be lower by a bias magnetic flux provided by the PM structure; the equilibrium point of the rotor can be adjusted by the magnetic force of the two electric magnets, which will not change the magnetic characteristic of the PM structure.Type: GrantFiled: April 8, 2011Date of Patent: June 16, 2015Assignee: CHUNG YUAN CHRISTIAN UNIVERSITYInventors: Yi-Hua Fan, Kuan-Yu Chen, Ying-Tsun Lee, Yi-Lin Liao
