PURPOSE: A driving device of a fully automatic washing machine is provided to prevent the damage of a bottom projection part of a core by forming a rib of a bottom insulator at an inner side of a coil of a higher position than the bottom projection part of the core. 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 stator assembly is formed with a core, a coil, a top insulator, a bottom insulator(460b), and an inner insulator in order to generate the rotary magnetic field. The core is formed by stacking a plurality of doughnut-shaped steel plates. The coil is wound around a pole(426). The top insulator is combined with a top end of the core. The bottom insulator(460b) includes a rib(470). The inner insulator is used for preventing the contact between the core and the coil. |
