其目的是通过大力发展永磁辅助凸极同步电机技术要素的研究，解决研究与实际应用之间所谓的“死亡之谷”。(1)通过对永磁体和极鞋形状的优化，找到了输出功率最大的机器结构。一个设计指南，以提高永磁辅助机器的性能，以充分发挥潜力已被发现。(2)考察了变频器驱动的弱磁场条件下永磁体的有效性和健康性。永磁体增加转矩的效果不仅存在于正常条件下，也存在于弱磁场条件下。建立了在逆变器驱动的弱磁场条件下进行测量的实验装置。永磁体的有效性和健康性已得到证实。

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.
