Abstract
A rotor having rotation salient poles, a stator having fixed salient poles with a plurality of field winding sets, K control signal output sections outputting signals by detecting a plurality of sections to be formed on a cylindrical body or a disk pivoted to the rotor by a plurality of sensors installed to correspond to the fixed salient poles with the plurality of sections to be detected are opposed to a track formed in a circumferential direction, and a power-feeding control section having control circuits operating according to control signals, controlling directions and intensities of excitation currents, where the rotation salient poles are opposed to at least two salient poles, and the excitation currents are controlled with magnetic fields in the same direction occur in rotation salient poles of the salient poles advanced by at least one and magnetic fields disappear in rotation salient poles.
