    Abstract: A washing machine and a control method thereof, capable of reducing noise by performing a zero-current control during the braking of a motor, and checking whether a vibration sensor is installed on a tub in a weight detection state in the beginning of a spin-drying. The zero-current control is performed by driving a current regulator with a command current set to “0 A”, so that the current flowing at the motor decreases and thus noise is reduced. In a washing machine having a vibration sensor fixedly attached to a tub, a fixation state of the vibration sensor with respect to the tub is checked in advance by use of measurement data of the vibration sensor at a weight detection stage in the beginning of the spin drying so that the frame touch caused by an erroneous detection of vibration or a failure of vibration detection may be prevented.

    Abstract translation: 一种洗衣机及其控制方法，其能够通过在电动机的制动期间进行零电流控制来降低噪声，并且在旋转开始时检查在重量检测状态下是否将振动传感器安装在桶上， 烘干。 通过将电流调节器的指令电流设置为“0 A”来执行零电流控制，使得流过电动机的电流减小，从而降低噪声。 在具有固定在桶上的振动传感器的洗衣机中，通过在旋转开始时的重量检测阶段使用振动传感器的测量数据，预先检测振动传感器相对于桶的固定状态 干燥，从而可以防止由错误的振动检测或振动检测失败引起的框架触感。

    Abstract: A washing machine and a control method thereof capable of determining whether a driving motor is locked. A pulsator is rotatably mounted in a spin basket, a driving motor generates rotational force, a clutch transmits the rotational force to the pulsator or the spin basket, a driving circuit supplies a driving current to the driving motor, and a control unit controls the driving circuit and the clutch so that the pulsator rotates in a forward or reverse direction and rotation of the spin basket is stopped in a washing or rinsing process. The control unit controls the driving circuit so that a motor lock detection current is supplied to the driving motor, and controls the clutch so that, if a rotating speed of the driving motor is less than a reference speed, the rotational force is transmitted only to the pulsator.
