Abstract: A washing machine includes a tub; a drum arranged in the tub; and a motor mounted on the rear wall, the motor including a stator and a rotor. The stator includes a stator core, a first insulator and a second insulator. The rotor includes a rotor frame including a bottom, air inlets formed at the bottom, and a side wall extended from the bottom. The first insulator is disposed between the stator core and the bottom of the rotor frame, the first insulator including at least one heat dissipation hole. The second insulator is disposed between the stator core and the rear wall of the tub, the second insulator including at least one guide member to position the second insulator on the rear wall of the tub. The guide member is exposed through the dissipation hole when the stator is coupled to the rear wall of the tub.
