    • A brushless rotary machine such as a brushless motor or a brushless generator is provided with first and second shafts. A rotor is fixed to the first shaft and rotated with the rotation of the first shaft, and magnetized when the rotor is fed with DC current. AC generator is mounted to the second shaft and generates AC current with rotation of the second shaft. The first and second shafts are separated and coupled to each other by a coupling mechanism having a space between the first and second shafts. In the space is provided a rectifier which is electrically coupled with the AC generator and the rotor, rectifies AC current generated by the AC generator into DC current and supplies the DC current to the rotor, thereby to magnetize the rotor.
    • 诸如无刷电动机或无刷发电机的无刷旋转机器设置有第一和第二轴。 转子固定在第一轴上并与第一轴的旋转一起旋转,当转子被供给直流电流时,转子被磁化。 交流发电机安装在第二轴上,并通过第二轴的转动产生交流电流。 第一和第二轴通过在第一和第二轴之间具有空间的联接机构分离并彼此联接。 在空间中设置有与交流发电机和转子电耦合的整流器,将由交流发电机产生的交流电流整流为直流电流,并将直流电流提供给转子,从而磁化转子。
