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.
