Abstract
A rotor of a motor includes a first rotor that includes a first rotor core and a plurality of first magnets that are coupled to an outer circumferential surface of the first rotor core, a second rotor that includes a second rotor core and a plurality of second magnets that are coupled to an outer circumferential surface of the second rotor core, and a third rotor that is stacked between the first rotor and the second rotor and includes a third rotor core and a plurality of third magnets that are coupled to an outer circumferential surface of the third rotor core, wherein magnetic fluxes of the plurality of third magnets are less than magnetic fluxes of the plurality of first magnets or second magnets.
