Abstract
An electrical rotating machine comprises: a stator including armature pole coils 14 capable of generating magnetic flux when energized; an inner rotor driven to rotate when the magnetic flux passes therethough; and an outer rotor in a magnetic path of the magnetic flux that passes through the first rotor, the outer rotor having portions of different materials, in permeability, which are situated along the periphery of the outer rotor, the inner rotor having a plurality of salient poles situated along the periphery of the inner rotor and wound by wound coils 34 which induce induced current when linked by the magnetic flux generated by the armature pole coils.
