Abstract
A rotor includes a rotor core formed by stacking electromagnetic steel sheets having anisotropy, which means that magnetic characteristics of the electromagnetic steel sheets in a first direction along a rolling direction are different from magnetic characteristics of the electromagnetic steel sheets in a second direction obtained by rotating the first direction by 90°, the rotor core having 4n magnetic pole portions formed along a circumferential direction, and magnets mounted in the rotor core in each of the magnetic pole portions. The 4n magnetic pole portions include a first magnetic pole portion formed in a region including the first direction and a second magnetic pole portion formed in a region including the second direction, and a total magnetic flux amount of the magnets per pole of the second magnetic pole portion is larger than a total magnetic flux amount of the magnets per pole of the first magnetic pole portion.
