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.
