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.

摘要： An inverter device provided on a washing machine for controlling a permanent magnet motor being provided with a rotor magnet including a first permanent magnet and a second permanent magnet having a level of coercivity smaller than the first permanent magnet. An excitation current is produced to vary the amount of magnetism of the second permanent magnet to execute a dehydrate operation with a magnetic flux of the rotor magnet reduced and to execute an operation being specified to operate at a lower maximum rotation count compared to the dehydrate operation with the magnetic flux of the rotor magnet increased. When the amount of magnetism of the second permanent magnet is varied while rotation of the permanent magnet motor is stopped, a phase of the excitation current for varying the amount of magnetism is switched depending on a rotation stop position of the rotor.
