An electrical steel sheet (300) is formed such that centerlines of four magnetic poles (salient poles) of a rotor core (111) coincide with a direction of easy magnetization (ED1) or (ED2). In addition, the electrical steel sheets (300) are laminated such that the directions of easy magnetization (ED1) and (ED2) are aligned.
