摘要： A direct drive washing machine is disclosed which is capable of performing a washing operation by efficiently converting electric energy supplied into an electric motor (10) into mechanical energy or with less vibration and noise. When a washing operation is carried out with efficient energy conversion, an acceleration time and a deceleration time of an agitator (8) rotated by the motor (10) are controlled on the basis of a measured value of a vibration sensor (25) or a measured value of clothes weight so that vibration of a water-receiving tub (4) becomes maximum. On the other hand, when a quiet washing operation with less vibration is carried out, the acceleration time and the deceleration time of an agitator (8) rotated by the motor (10) are controlled on the basis of the measured value of the vibration sensor (25) or the measured value of clothes weight so that vibration of the water-receiving tub (4) becomes minimum.
