Abstract

PURPOSE:To perform a wide range of controls corresponding to the sorts of garments to be washed and prevent uneven washing and damages on the garments by a method wherein a controller calculates and stores the average values of the speed and angle of a motor in preparatory operation, and washing operation is carried out after the speed and angle of an agitator are set based on the stored data. CONSTITUTION:During preparatory operation, the motor speed and angle signals respectively detected by a speed detecting circuit 27 and an angle detecting circuit 28 of a speed/angle detector 21 are input to a controller 26 which calculates and stores the average values of the speed and angle. A DC brushless motor 24 has a characteristic of a linear relationship between the rotational frequency and the torque, and the rotational frequency and the torque of the motor 24 decrease with a reduction in the applied voltage. Then, the controller 26 sets a rotational frequency and angle suitable for the load based on the stored rotational frequency and angle, controls the applied voltage to the motor 24 by a voltage control circuit 25 so as to obtain the set values, and outputs the controlled voltage to the motor 24.
