摘要： Device and method for detecting malfunction of a clutch in a washing machine, the device including a clutch including a coupling for transmission of a power from a motor to a washing shaft or a spinning shaft, a clutch motor (60) for providing a power to the coupling, a switch for controlling the coupling, and a cam (600) fitted to be rotatable with the clutch motor for turning on/off the switch in response to the rotation, a power supplying part for supplying a voltage to the motor and the clutch motor (60), a pulse counting part for counting a number of pulses of a voltage supplied to the clutch motor from the power supplying part, and a microcomputer for repeating a process in which the clutch motor is stopped for a second set time period (S20) and operated again if the switch is not switched for a first set time period from a time the clutch motor is put into operation, and informs to a user that the clutch is in malfunction if the switch is not switched while the process is repeated equal to or more than a set times, thereby determining the clutch of being out of order and informing a result of the determination to a user.

摘要： ABSTRACTA method of controlling a motor-driven washing machine and a control system that controls a motor or any other components of the washing machine are disclosed. The method includes the steps of generating an interruption command for braking a motor in motion during a wash cycle, applying a phase-reversed voltage to a voltage input terminal of the motor in motion, and electrically shorting the input terminal of the motor for a predetermined period of time if a second phase-reversed voltage generated by the motor is higher than or equal to a critical voltage level. Using such method, a motor-clutch mechanism is prevented from generating a noise and from being damaged during a wash cycle.
