Outline of Final Research Achievements

In two-axis actively positioned bearingless motors, radial axes x and y are actively positioned. Axial and tilting directions are passively stabilized. In one-axis actively positioned bearingless motors, only axial z is actively positioned, and the other axes are passively stabilized. These bearingless motors with reduced active positioning axes have simple control system and low cost. However, a resonant vibration is serious problem. Therefore, in this research, a novel vibration suppression method and a regulation system are proposed and verified in the experiments.
