Abstract
A rotary electric machine includes: a stator; a rotor; a control device that causes the stator to generate a rotating magnetic field; and a magnetic flux supply element supported by a rotary shaft so as to be rotatable relative to the rotary shaft, disposed radially inward of the rotor across a gap, and having auxiliary magnets. Each auxiliary magnet is formed such that opposite end portions thereof in the circumferential direction are radially opposed to holding magnets when the relative rotation angle of the magnetic flux supply element is a strengthening angle. The control device executes field weakening control or field strengthening control, thereby changing the relative rotation angle of the magnetic flux supply element.
