Kind Code:
A1
Abstract:
An aspect of a motor of the present invention comprises: a rotor rotatable about a central axis; and a stator opposed to the rotor in the axial direction. The rotor comprises: a frame yoke including a plurality of accommodation holes in a circumferential direction; a cover yoke provided on one side in the axial direction of the frame yoke; and a group of a plurality of magnets respectively accommodated in the plurality of accommodation holes, the other side of which in the axial direction is opposed to the stator. The group of a plurality of magnets comprises: a main magnet having a magnetization direction in the axial direction; and a plurality of sub magnets that are in contact with the main magnet, are arranged to surround at least a part of a periphery of the main magnet, and have a magnetization direction in the direction orthogonal to a contact surface of the main magnet.
