Abstract: The present disclosure relates to a motor. The motor can include a stator defining an interior space, a rotor disposed in the interior space of the stator. The rotor can include a body defining a structure and a plurality of magnets disposed in the plurality of cavities. In some embodiments, the structure defines a plurality of cavities in the body of the rotor, the plurality of cavities includes at least a first cavity and a second cavity, the first cavity is spaced radially outward from the second cavity, and a thickness of the first cavity is larger than a thickness of the second cavity. In some embodiments, at least some of the cavities of the plurality of cavities have a magnet from the plurality of magnets disposed therein.
