Abstract:
A rotor includes a rotor core, a first magnet, a second magnet, a first pole partition line, and a second pole partition line. The first and second magnets are provided inside the rotor core and between the first and second pole partition line. The first magnet is closer to the first pole partition line than to the second pole partition line, and the second magnet is closer to the second pole partition line than to the first pole partition line. A distance between the first and second magnets at a position is wider as the position is closer to a circumference portion of the rotor core. The first magnet and the first pole partition line have a first minimum distance therebetween, the second magnet and the second pole partition line have a second minimum distance therebetween, and the first minimum distance is smaller than the second minimum distance.
