| Research Abstract |
The purpose is to resolve the so-called "valley of death" between the research and the practical application by significantly developing the study on the technology elements of permanent-magnet-assisted salient-pole synchronous machines. (1) The machine structure in which the output power is maximized has been found by optimizing the shapes of the permanent magnets and the pole shoes. A design guide to improve the performance of the permanent-magnet-assisted machine to the fullest potential has been found. (2) The effectiveness and healthiness of the permanent magnets under field-weakening conditions driven by inverters are examined. The effect of increasing the torque by the permanent magnets exists not only under normal conditions but under field-weakening conditions. The experimental setup to perform measurements under field-weakening conditions driven by inverters has been built. The effectiveness and healthiness of the permanent magnets have been confirmed.
