Claim:
1. A washing machine comprising: a tub provided with a rear wall; a drum arranged in the tub; and a motor mounted on the rear wall of the tub to drive the drum, the motor including a stator and a rotor, wherein the stator comprises a stator core, a first insulator and a second insulator disposed on an opposite side of the first insulator so as to cover the stator core, wherein the rotor comprises a rotor frame including a bottom, air inlets formed at the bottom, and a side wall extended from the bottom, wherein the first insulator comprises a plurality of heat dissipation holes arranged in a circumferential direction of the first insulator to dissipate heat of the stator core, wherein the second insulator is disposed between the stator core and the rear wall of the tub, the second insulator including a plurality of guide holes arranged in a circumferential direction of the second insulator to be coupled to a plurality of guide protrusions protruded from the rear wall of the tub, and wherein each of the guide holes is exposed through one of the plurality of heat dissipation holes while the first insulator and the second insulator are coupled to each other.
