  • Patent number: 8084983
    Abstract: There are provided a laundry treatment machine and a method of controlling the same. A temperature around a motor is sensed and the range of current input to the motor in accordance with the sensed temperature is limited in stages. Therefore, the surrounding of the motor can be prevented from being overheated. In addition, since the range of the current input to the motor is limited in stages, when the current applied to the motor is limited, abnormal noise is not generated and the torque of the motor can be maximized.
    Type: Grant

  • Publication number: 20090064722
    Abstract: There are provided a laundry treatment machine and a method of controlling the motor of the laundry treatment machine. In the laundry treatment machine and the method of controlling the motor of the laundry treatment machine, when it is sensed that the motor is overloaded, the motor is driven by setting the rotation starting point of the motor back from the previously set position. Therefore, the motor is prevented from being restrained due to the overload of the motor so that it is possible to prevent the abnormal noise of the motor from being generated, to prevent the temperature from rising, and to improve the mobility of the motor.
