Abstract

A rotary electric machine includes a rotor, a stator, a bypass core, a flux regulation coil, and a controller. The bypass core is opposed to protruding portions, and the protruding portions are provided on opposite sides of magnets provided in a rotor core as viewed in a direction of magnetization of the magnets, and protrude toward the bypass core from a surface of the rotor to which the magnets are exposed. The flux regulation coil is configured to regulate the magnetic flux passing through the bypass core. The controller is configured to control a current applied to the flux regulation coil such that the magnetic flux passing through the bypass core when the current is applied to the flux regulation coil is smaller than the magnetic flux passing through the bypass core when the current is not applied to the flux regulation coil.
