Abstract
A rotor includes at least one first permanent magnet and at least one second permanent magnet. The at least one first permanent magnet forms part of an outer peripheral surface of the rotor and is magnetized to have polar anisotropy. The at least one second permanent magnet is adjacent to the at least one first permanent magnet in a circumferential direction of the rotor and has lower magnetic force than magnetic force of the at least one first permanent magnet.
