    • An electric motor comprising an inner periphery side rotor provided with inner peripheral permanent magnets with unlike poles, which are disposed alternately along a circumferential direction of the inner periphery side rotor, an outer periphery side rotor provided with outer peripheral permanent magnets with unlike poles, which are disposed alternately along a circumferential direction of the outer periphery side rotor, and a rotating device that varies a relative phase between the inner periphery side rotor and the outer periphery side rotor by rotating at least the inner periphery side rotor or the outer periphery side rotor around the rotational axis. The outer peripheral side rotor is arranged such that a rotational axis thereof is coaxial with a rotational axis of the inner periphery side rotor. The rotating device sets a variable width of the relative phase between the inner periphery side rotor and the outer periphery side rotor within a range of an electrical angle of below 180°.
    • 一种电动机,包括内周侧转子,该内周侧转子设置有沿着内周侧转子的周向交替设置的具有不同极的内周永磁体,外周侧转子设置有具有不同极的外周永久磁铁, 沿外周侧转子的圆周方向交替设置旋转装置,该旋转装置至少使内周侧转子或外周侧转子旋转,从而使内周侧转子和外周侧转子之间的相对相位变化 围绕旋转轴。 外周侧转子的旋转轴与内周侧转子的旋转轴线同轴配置。 旋转装置在电角度低于180°的范围内设定内周侧转子和外周侧转子之间的相对相位的可变宽度。
