Abstract
A rotor core has installation portions in which first magnets, which are permanent magnets, are arranged. The installation portions are larger than the first magnets. The first magnets are divided into a first group and a second group. The first magnets in the first group are fixed to the installation portions to be offset in the positive rotational direction of the rotor toward the pseudo magnetic poles or the different magnetic poles. The permanent magnets in the second group are fixed to the installation portions to be offset in the inverse rotational direction of the rotor toward the pseudo magnetic poles or the different magnetic poles.
