| Outline of Final Research Achievements |
For further downsizing, energy saving, simplification, and cost reduction, three types of new structures and topologies for a magnetically levitated motor system have been developed. Type 1: a single-drive bearingless motor which employs only one three-phase inverter and one set of three-phase winding, where a d-axis current produces suspension force. Type 2: a magnetic bearing motor system using a zero-phase current for 1-DOF controlled magnetic suspension. The zero-phase is connected between the neutral point of the star connected three-phase winding and the middle point of the power source. Type 3: a 2-DOF controlled bearingless motor using zero-phase current for single-phase motor drive. The three-phase winding is used for 2-DOF magnetic suspension. In all types, experimental apparatus and machines were built and tested. The test results have demonstrated the usefulness and effectiveness of the proposed novel three concepts of the magnetically levitated motor system.
