    • A rotor body for an electric motor is comprised of connecting outer peripheral portions of first and second flange members made of electrically conductive material to the opposite ends of a plurality of connection members made of electrically conductive material of weak magnetic material arranged at predetermined distances therebetween in the circumferential direction with bolts and by supporting induction magnetic poles made of soft magnetic material between the connection members which are adjacent in the circumferential direction. Coupling portions of the first and second flange members and the connection member are electrically insulated by insulation coating so that an eddy current flowing in a closed circuit comprised of the first flange member, the connection member, the second flange member and the other connection member can be reduced and heat dissipation and energy loss accompanied by the eddy current can be minimized at the time of an operation.

    • An electric motor (M) includes first and second stators (12L, 12R) on the outside forming a rotating magnetic field, an outer rotor (13) disposed inside the first and second stators (12L, 12R) and having first and second induced magnetic poles (38L, 38R), and an inner rotor (14) disposed inside the outer rotor (13) and having first and second permanent magnet (52L, 52R). The phases of the first and second induced magnetic poles (38L, 38R) of the outer rotor (13) are displaced from each other by only half of a predetermined pitch, and the phases of the first and second permanent magnets (52L, 52R) of the inner rotor (14) are displaced from each other by only the predetermined pitch. Accordingly, the first and second stators (12L, 12R) facing the first induced magnetic poles (38L) and the second induced magnetic pole (38R) can be made to have the same phase and polarity, thus simplifying the structures of the first and second stators (12L, 12R).
    • 电动机(M)在外部包括形成旋转磁场的第一和第二定子(12L,12R),设置在第一和第二定子(12L,12R)内的外转子(13),并具有第一和第二感应磁 (38L,38R)和设置在外转子(13)内部并具有第一和第二永磁体(52L,52R)的内转子(14)。 外转子(13)的第一和第二感应磁极(38L,38R)的相位彼此偏移预定间距的一半,并且第一和第二永磁体(52L,52R)的相位 内转子(14)彼此偏移预定的间距。 因此,可以使面对第一感应磁极(38L)和第二感应磁极(38R)的第一和第二定子(12L,12R)具有相同的相位和极性,从而简化了第一和第二定子 定子(12L,12R)。
