PURPOSE: A driving device of a fully automatic washing machine is provided to cool the heat generated from a stator assembly by forming a plurality of fan members at a top end ring of a rotor assembly. CONSTITUTION: A driving device of a fully automatic washing machine includes a drying shaft, a washing shaft, a clutch housing, a stator assembly, a rotor, and a rotor frame. The drying shaft is formed with a top drying shaft, a bottom drying shaft, and a drum for connecting the top drying shaft to the bottom drying shaft. The washing shaft is formed with a top washing shaft, a planetary gear for transmitting torque to the top washing shaft, and a bottom washing shaft. The clutch housing is used for covering the drying shaft. The stator assembly is formed with a core and a coil part. The rotor is located around an outer circumference of the stator assembly. The rotor frame is used for fixing the rotor. The rotor is formed with a rotor core, a metal bar(514), a top end ring(516), and a bottom end ring(518). The rotor core is formed by stacking plural steel plates having plural holes. The metal bar(514) is used for filling the holes of the rotor core. A plurality of fan members are formed at the top end ring(516). The top end ring and the bottom end ring(518) are connected to both ends of the metal bar in order to form a closed circuit of the secondary current. The top end ring includes a plurality of fan members(516a).
