    • In a method of manufacturing a self-start synchronous motor for preventing deterioration of permanent magnets used in a rotor, and also for enhancing the efficiency of the self-start synchronous motor, the self-start synchronous motor comprising a stator having a stator core and windings wound around the stator core, and a rotor having an outer diameter slightly smaller than an inner diameter of the stator and arranged inside of the stator. The rotor is provided with a rotor core, a plurality of conductor bars embedded in the outer peripheral portion of the rotor core over an entire periphery thereof, end rings provided on opposite end sides of the conductor bars and constituting a squirrel cage conductor in cooperation with the conductor bars, and a plurality of permanent magnets embedded in the rotor core and arranged at a position inner than that of an inner peripheral surface of the conductor bars. Further, the conductor bars and the end rings are electrically and mechanically joined together through frictional agitation joint.
    • 在制造用于防止转子中使用的永磁体的劣化的自启动同步电动机的制造方法中,为了提高自启动同步电动机的效率,该自启动同步电动机包括定子,该定子具有定子铁心和 缠绕在定子芯上的绕组和具有比定子的内径稍小的外径的转子,并且配置在定子的内部。 转子设置有转子芯,多个导体条,其在转子芯的整个外周上嵌入转子芯的外周部分,端环设置在导体条的相对端侧,并与 导体棒和嵌入在转子芯中的多个永磁体,并且配置在内导体棒的内周面的位置。 此外,导体条和端环通过摩擦搅动接头电连接和机械连接在一起。
