Abstract: A motor includes a stator, a rotor including an outer rotor core that includes a plurality of magnets arranged along a circumferential direction of the rotor, an inner rotor core that is located radially inward of the outer rotor core and that defines a shaft hole configured to receive a shaft, and an inner connecting portion that connects the outer rotor core to the inner rotor core and that is located at a central axis of a magnet from among the plurality of magnets. The inner connecting portion includes a radial rib that extends from the inner rotor core radially outward toward the outer rotor core, and an extension rib that extends from an outer end of the radial rib in the circumferential direction and that defines an angle with respect to the radial rib that is greater than or equal to 90 degrees.

Abstract: A motor including a stator includes a first stator core, and a second stator core that is independent from the first stator core and that is symmetric to the first stator core with respect to a vertical line that passes through a center of the stator. Each of the first and second stator cores includes a yoke, a center tooth that extends from a center of the yoke toward the center of the stator, and outer teeth that extend from a first end of the yoke and a second end of the yoke, respectively. The center tooth is located between the outer teeth, and a length of the outer teeth is greater than a length of the center tooth.
