Abstract (en)
The balance of the laundry sticking to an inner peripheral surface of a drum of a drum washing machine having a drum rotating on a substantially horizontal axis is adjustedbefore spin-drying. A brushless DC motor is adopted for a drum drive motor. The motor current is separated into a d-axis current and a q-axis current to carry out speed control by vector control for controlling these currents independently. Before spin-drying, the rotating speed is increased (S1) up to a speed at which the laundry sticks firmly to the inner peripheral surface of the drum. Then, the machine enters the rotating speed slow-down operation mode (S2) in which the rotating speed is gradually decreased. The balance of the laundry inside the drum is judged to be proper during the speed slow-down, the rotating speed is increased to enter a spin-drying mode (S8). The balance of the laundry inside the drum is judged on the basis of the fluctuation width of the q-axis current. <IMAGE>
