Abstract
In a rotor, magnetic poles having a pair of first magnets and second magnets are provided along a circumferential direction. The magnetic pole includes a pair of first flux barrier portions radially outside the first magnets, and a pair of second flux barrier portions between the pair of first flux barrier portions in the circumferential direction. The first flux barrier portion has a first end close to the adjacent second flux barrier portion. The second flux barrier portion has a second end close to the adjacent first flux barrier portion. A relative position of the first end in the circumferential direction with respect to a circumferential center of the magnetic pole is different between the adjacent magnetic poles. A relative position of the second end in the circumferential direction with respect to the circumferential center of the magnetic pole is different between the adjacent magnetic poles.
