要約(日本語): In this paper, the feasibility study for a new type of bearingless motor is carried out by FEM analyses and experiments. The feature of the proposed bearingless motor is using a rotor with rectifier coil, which makes the rotor act as a permanent magnet. The optimum geometrical dimensions of the proposed bearingless motor are determined by comparing the rotor torques at various rotor tooth lengths. The dimension with which the motor has relatively minimum fluctuation and sufficient torque is chosen to build a test machine. In order to generate the radial forces, a control current arrangement is proposed. FEM analyses are also used for evaluating the property of the proposed arrangement. The radial force control for the proposed bearingless motor has been verified by experimental results.
