Abstract: Disclosed is a motor comprising a stator and a rotor, wherein the rotor comprises a plurality of rotor cores and a plurality of magnets, and wherein the magnet is configured to have a face facing the center of rotation of the rotor exposed. Accordingly, a motor may minimize a non-magnetization area and enable a magnet to be fully magnetized, when it comes to post magnetization of the magnet.
