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.

Abstract: An insulator is configured to couple to a top portion of a stator core and includes: a main body that has a ring shape; a plurality of insulating teeth that protrude toward a center portion of the main body and that are configured to couple to a plurality of teeth of the stator core, respectively; and a plurality of guide tabs that protrude from an outer circumferential surface of the main body at positions corresponding to the plurality of insulating teeth. The plurality of guide tabs are configured to guide (i) phase coils that are wound around the plurality of insulating teeth and (ii) neutral coils along the outer circumferential surface in a circumferential direction. Each of the plurality of guide tabs defines a plurality of guide grooves, each of the plurality of guide grooves being configured to seat at least one of the phase coils or the neutral coils.
