Abstract

The laundry treatment machine includes an inverter to convert direct current (DC) voltage into alternating current (AC) voltage and to output the AC voltage to a motor. The laundry treatment machine includes an inverter controller to control the inverter to supply current corresponding to a direction opposite to back electromotive force generated from the motor to the motor so as to align the motor during a starting operation of the motor. It is feasible to rapidly align a rotor of the motor during the starting operation of the motor.
