Claim:
1. A rotor for a rotary electric machine, comprising: a rotor core; and a plurality of teeth, each of which is formed by a plurality of plate members including steel plates that are stacked together, and around which a rotor coil is wound, each of the plurality of teeth including a trunk portion extending in a radial direction from the rotor core, at least a portion of the plurality of teeth including a magnetic flux inducing section, the magnetic flux inducing section protruding between trunk portions of two of the teeth that are adjacent to one another, from at least a portion of a plurality of plate members that form at least one of the two teeth that are adjacent to one another, and the magnetic flux inducing section being formed by the plate members, a portion of the rotor coil is wound around the plurality of teeth in a position farther toward a radial distal end of the plurality of teeth than the magnetic flux inducing section, wherein the magnetic flux inducing section is a plurality of magnetic flux inducing portions that includes a plurality of one-side magnetic flux inducing portions that protrude from a plurality of locations in an axial direction of the trunk portion of one of the two teeth that are adjacent to one another, and a plurality of other-side magnetic flux inducing portions that protrude from a plurality of locations in the axial direction of the trunk portion of the other of the two teeth that are adjacent to one another, wherein the one-side magnetic flux inducing portions and the other-side magnetic flux inducing portions are fixed together.
