Abstract
Each of a plurality of permanent-magnet pairs is configured with a pair of permanent magnets that are arranged in a v-shaped manner in such a way that the distance between the portions of the permanent magnets, facing each other at the outer side in the radial direction of the rotor core, is smaller than the distance between the portions thereof, facing each other at the inner side in the radial direction of the rotor core; a magnetic-field pole is formed of part, of the rotor core, that is situated between the adjacent permanent-magnet pairs.
