This invention relates to a method and apparatus for controlling the speed of a washing machine motor by varying the number of revolutions and changing direction of rotation of the motor to control the water current of the washing machine. The invention detects the actual speed of the washing machine motor at every half cycle of ordinary use power frequency, determines speed error by comparing the detected actual speed with an ordered speed, determines a speed state from the speed error, calculates a proportional integration value according to the determined speed state, and scales the calculated proportional compensation value into an angular value. The washing machine's motor speed is controlled using the scaled angular value.
