PURPOSE:To perform controls of a wide range and prevent garments from being unevenly washed and damaged by a method wherein a controller is provided with a numeric data entry device, by which the rotational speed and angle of an impeller are set, and a display on which those data are indicated. CONSTITUTION:When a motor 24 is started to perform washing, the magnetic pole position information is input to a controller 26 by a magnetic pole position detector 20 through a magnetic pole position detecting circuit 23, and the controller 26 makes a transistor module 22 perform on-off controls of six built-in transistors through a base driving circuit 23 and energize three-phase coils of U, V and W phases corresponding to the magnetic position information. When the rotational speed and angle of an agitator impeller are set in the controller 26 by the numeric data entry device, those input data are indicated on a numeric data display. When those data are within specified values, the controller 26 sets a rotational speed and an angle suitable for those data, controls the voltage to be applied to a motor 24 by a voltage control circuit 25 so as to achieve the set value, and outputs the controlled voltage to the motor 24. |
