Rotor

A rotor comprising:

• a rotor core formed by stacking electromagnetic steel sheets having anisotropy, the anisotropy meaning that magnetic characteristics of each of the electromagnetic steel sheets in a first direction along a rolling direction are different from magnetic characteristics of each of the electromagnetic steel sheets in a second direction obtained by rotating the first direction by 90°, the rotor core having 4n (n is a natural number) magnetic pole portions formed along a circumferential direction;
• and
• magnets mounted in the rotor core in each of the magnetic pole portions,
• wherein 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
• wherein 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.
