摘要： This invention relates to a method for braking a washing machine comprising the steps of: determining whether or not a motor is braking; transmitting a PWM (Pulse Width Modulation) control signal by setting up the initial phase and the duty ratio according to the voltage flows in the system when an operation mode determined by the previous step as a braking mode; comparing a capacity and a variance of the detected voltage with a reference voltage predetermined during the previous step; and controlling a motor driver by re-establishing the control phase and the duty ratio are re-established until the motor is stopped when the comparison result of the previous step indicates that the capacity and the variance of the voltage are lower than the predetermined reference level.

摘要： A method for braking a washing machine in accordance with the present invention comprising the steps of: setting up an initial data of a duty ratio corresponding to a detected speed and a rotating position; discharging a voltage of the capacitor filter during a duty-on cycle according to the duty ratio set up in the preceding step; and charging a voltage to the capacitor filter during duty-off cycle when the duty-on cycle of the preceding step is finished. As described above, the dynamic braking resistor is not used in the method for braking the washing machine according to the present invention so that the size and the production cost are reduced.
