Abstract
A high-efficiency magnetic inductor rotary machine in which eddy current loss is reduced even if driven at super-high-speed rotation, and a fluid transfer apparatus that uses the same. In the magnetic inductor rotary machines, first and second stator cores are disposed coaxially such that circumferential positions of teeth are aligned, and first and second rotor cores are fixed coaxially to a rotating shaft such that salient poles are offset by a pitch of half a salient pole circumferentially, and are disposed on an inner peripheral side of the first and second stator cores. A salient pole width of the salient poles of the first and second rotor cores is configured so as to be greater than an opening width of slots of a stator.
