Abstract
A consequent-pole-type rotor includes a first rotor core having a first insertion hole, and a second rotor core having a second insertion hole, the second rotor core being stacked on the first rotor core such that the first insertion hole and the second insertion hole together form a space accommodating a permanent magnet. The first insertion hole has an opening at a first circumferential position of the first rotor core, and the second insertion hole is occluded at least at a second circumferential position of the second rotor core. The second circumferential position corresponds to the first circumferential position.
