| Research Abstract |
A novel 5-DOF actively controlled self-bearing motor that combines the functions of a motor, two radial AMBs, and an axial AMB has been proposed. It is possible to downsize and high efficiency with maintaining high performance simultaneously. With the derivation of theoretical control forces, prototype of the first IPM type 5-DOF self-bearing motor was made based on the three dimensional magnetic field analyses. The experimental results showed that the prototype rotor generates considerable cogging torque and the stable rotation with levitation. Therefore the flux recovery type permanent magnets configuration has been proposed and second IPM type one is made. It achieved a major reduction of the cogging torque. In addition, the proposed flux recovery type one improved the fundamental motor characteristics.
