ROTOR AND MOTOR INCLUDING SAME

Disclosed are a rotor that is capable of more efficiently using magnetic flux from magnets and a motor including the same. The rotor includes a plurality of rotor cores, a plurality of magnets magnetized such that magnetic flux is formed in the circumferential direction, the magnets and the rotor cores being alternately arranged in the circumferential direction, a coupler connected to a shaft, and a rotor frame including a coupler base connected to the coupler, an extension base extending from the coupler base in the radial direction, and a rotary base extending from the extension base in the axial direction of the shaft for supporting the rotor cores and the magnets while surrounding the rotor cores and the magnets, wherein the coupler base, the extension base, and the rotary base are integrally formed by injection molding, and the rotor frame is coupled to the coupler, the rotor cores, and the magnets, and wherein the extension base is provided with crossing ribs that cross in the radial direction.
