摘要： The present subject matter relates to methods and apparatus for controlling operation of a washing machine motor. Different control algorithms may be used during different time periods of operation of the motor where each algorithm is configured to provide different operating characteristics of the motor based on the needs of the washing machine system. The method and apparatus both provide for changing from one motor control algorithm to another algorithm while the motor is spinning. For certain type motors, a time period may be established between operation of the motor under a first or second control algorithms where no energy is supplied to the motor but the motor is permitted to continue to spin. During this period of time for these type motors, magnetic fields in the motor are permitted to subside prior to application of the second control algorithm.

摘要： Provided is a driving device for a full automatic washing machine in which a clutch unit can stop rotation of a dehydration axis without having a particular brake unit, since the clutch unit is closely adhered to a first dehydration axis and a bushing when the rotation of the dehydration axis is controlled according to a wash or dehydration stroke in a full automatic washing machine. In addition, since a clutch coupler of the clutch unit moves at a wash or dehydration stroke in a driving device of a washing machine to thus be attached to and detached from a clutch gear which controls rotation of the first dehydration axis, and to thereby control a rotational force which is transferred to an inner tub, the washing machine is embodied to have a simple clutch coupling structure. Further, a double-rotor and a single-stator of a brushless direct-current (BLDC) motor which is applied to a driving device of a washing machine are insert-molded into a waterproof structure, to thus maximize a contact area of a bulk molding compound (BMC) molding material to thereby maximize durability.
