Abstract
Object of the present invention lies on improving a system stability by reducing an allowable eccentricity of laundry below a preset value when a spinning speed reaches to a maximum even if a voltage higher than a rated voltage is applied, by varying a maximum limit of a lead angle with a voltage applied to a drum type washing machine. For achieving the object of the present invention, in a method for controlling a spinning speed of the present invention, a maximum value of a lead angle is set to vary with an applied voltage after detection of the applied voltage.
