ABSTRACT:
A method and apparatus for braking a washing machine, capable of enhancing a braking reliability and a braking efficiency by simultaneously or selectively applying a mechanical band brake and an electrical brake. In the washing machine, a shaft of a driving motor and a central shaft of the dehydrating tub are formed on a straight line in a single shaft structure, and a reduction gear unit, a band brake assembly and a clutch assembly are axially and successively installed. When a door of the washing machine is opened, the dehydrating tub is braked by electrically stopping the motor or by operating the band brake assembly. On the other hand, when the door is closed, the dehydrating tub is braked only by electrically stopping the motor.
