摘要:
A system and method of controlling a motor-driven washing machine, the method comprising the steps of initiating a wash cycle by operating a motor provided in the washing machine according to a washing option selected by a user, generating a motor-brake signal to brake the operation of the motor when a motor-interruption command is generated and measuring a brake period which represents a total length of time it takes to completely stop the operation of the motor, determining malfunction of the motor based on whether the measured brake period exceeds a predetermined period of time and displaying a warning message on a display unit, the message indicating the determined malfunction of the motor.

A system and method of controlling a motor-driven washing machine, the method comprising the steps of (S933) determining whether a first current speed of a motor (912) is greater than a first predetermined speed (W1) if a motor-interruption of the motor (912) is generated during a spin cycle, the motor (912) rotating a washing tub containing a load of clothes to be dehydrated during the spin cycle, and (S934) braking the motor (912) in motion by shorting power terminals of the motor (912) for a first predetermined period if the first current speed is greater than the first predetermined speed (W1).

摘要:
Provided is an apparatus and method for controlling a washing/drying system including a washing machine and a dryer used in one pair. Since the washing machine can communicate with the dryer according to a wireless communication regulation, the dryer can operate more conveniently. According to the apparatus and method, convenience in using the washing machine and the dryer together is further enhanced.
