Abstract
A motor includes a cylindrical rotor core, and a magnet group including first magnets and second magnets alternately arranged along a circumferential direction of the rotor core. A first magnetic flux line generated in the first magnets extends along a radial direction of the rotor core, and a second magnetic flux line generated in the second magnets is inclined with respect to the first magnetic flux line. The rotor core includes an inner portion located on a radially inner side of the magnet group and an outer portion located on a radially outer side of the magnet group. The outer portion includes a first iron core that covers the first magnet from the radially outer side, and a second iron core that covers at least a portion of the second magnet in the central axis direction of the rotor core from the radially outer side.
