Abstract:
In a rotary electric motor a first stator core and a second stator core are disposed coaxially so as to be separated by a predetermined distance axially and such that circumferential positions of teeth are aligned, and a first rotor core and a second rotor core on which salient poles are disposed at a uniform angular pitch circumferentially are fixed coaxially to a rotating shaft so as to be positioned on inner peripheral sides of the first stator core and the second stator core, respectively, and so as to be offset circumferentially by a pitch of half a salient pole from each other. A first permanent magnet that is magnetically oriented such that a direction of magnetization is radially inward is disposed on an outer peripheral surface of a core back of the first stator core, and an outer peripheral surface of the first permanent magnet and the outer peripheral surface of the core back of the second stator core are linked by a frame that is made of a magnetic material.
