Rotor and motor

A rotor comprising:

• first and second rotor cores, each including a generally disk-shaped core base and a plurality of claw-poles, wherein the claw-poles are arranged at equal intervals on an outer circumference of the core base, each of the claw-poles projects toward an outer side in a radial direction and extend in an axial direction, the core bases of the first and second rotor cores are opposed to each other, and the claw-poles of the first and second rotor cores are alternately arranged in a circumferential direction;
• a disk magnet arranged between the core bases in the axial direction, wherein the disk magnet is magnetized in the axial direction so that the claw-poles of the first rotor core function as first poles and the claw-poles of the second rotor core function as second poles;
• and
• a rectifying magnet including at least one of an inter-pole magnet portion and a back-surface magnet portion, wherein the inter-pole magnet portion is located in a gap formed in the circumferential direction between the claw-poles of the first rotor core and the claw-poles of the second rotor core, and the back surface magnet portion is located in a gap formed at back surfaces of the claw-poles, wherein
• the rectifying magnet and the disk magnet are formed from different materials, and
• the rectifying magnet is integrated with the disk magnet in a post-process.
