Abstract
A rotor having an axial direction includes at least a pair of rotor cores arranged in the axial direction, and a field magnet located between the rotor cores and magnetized in the axial direction. Each of the rotor cores includes a plurality of claw poles extending in the axial direction. Each of the rotor cores includes a magnetic flux controlling section, which appropriately causes a magnetic flux to flow to the claw poles.
