Beschreibung
Zusammenfassung:	A surface magnet rotor includes a shaft member extending along a rotational axis, and a magnet portion formed around the shaft member and forming opposite magnetic poles arranged along a circumferential direction. A cross-section of the shaft member includes an intermediate line extending from the rotational axis to a center point in the circumferential direction between a d-axis and a q-axis of the magnet portion. In the cross-section, a first cross-sectional area delimited by the d-axis and the intermediate line is different from a second cross-sectional area delimited by the q-axis and the intermediate line.
