Abstract

A rotary electric machine includes a rotor that rotates around a rotation axis serving as a center and has a plurality of salient poles protruding in directions perpendicular to the rotation axis, and a stator that includes an annular structural body disposed radially outside the rotor and surrounding the rotor, and 6×n windings provided along a circumferential direction of the structural body, a field signal for generating field magnetic flux and a drive signal for driving the rotor as a three-phase rotary electric machine being superimposed on each other to be input to each of the windings. n is a natural number equal to or larger than one.
