Abstract: A compressor motor and a compressor including a compressor motor are provided. The compressor motor may include a stator and a rotor. The rotor may include a rotor core and a plurality of magnets disposed on a radially outer surface of the rotor core. The rotor core may include a plurality of seating grooves in which the plurality of magnets is respectively seated, and a plurality of protrusions that protrudes radially outward between the plurality of seating grooves. The magnet may slide axially between adjacent protrusions of the plurality of protrusions, an inner surface of the magnet may be seated in the seating groove, and at least a portion of a side surface of the magnet may contact a side surface of the protrusion. The side surface of the magnet may extend and protrude further radially outward than the side surface of the protrusion, and a fixing layer may be disposed in at least a partial area radially outward of the outer peripheral surface of the protrusion.
