PROBLEM TO BE SOLVED: To further reduce operation vibration and operation noise in spite of a structure that a stirring body and a revolving tub are rotatively driven by a brushless motor by a direct drive method. SOLUTION: This washing machine is provided with the revolving tub rotatably provided in an outer tub, the stirring body rotatably disposed in the revolving tub, the brushless motor 20 rotatively driving the stirring body or the stirring body and the revolving tub by the direct drive method, a Hall IC 31 detecting the rotation position of the rotor of the brushless motor 20 and outputting a position sensor signal, a control means 67 forming a nearly sinusoidal excitation signal based on the position sensor signal from the Hall IC 31, and a motor exciting means 58 exciting the brushless motor 20 based on the excitation signal from the control means 67.
