| Outline of Final Research Achievements |
In this study, a small and high-performance 5-DOF self-bearing motor is proposed and developed for a biventricular assist device. It possesses the function of a motor, two radial magnetic bearings, and an axial magnetic bearing. The rotor consists of two reluctance type rotors, two homopolar permanent magnets and a circular disc located in the middle position. The homopolar PMs generate high bias magnetic fluxes. Furthermore, in the radial control and the axial control, the fluxes don’t interfere at simultaneous control and the radial direction forces can be controlled without any rotating magnetic field information. The proposed motor models are analyzed by three dimensional finite element methods. From the results, the experimental setup are made and tested. The levitation tests are going on. However, the result of motor efficiency is low. Then a homopolar-consequent integrated type 5-DOF self-bearing motor is newly proposed.
