Zusammenfassung:	A motor driving apparatus and a laundry treatment machine including the same are disclosed. The laundry treatment machine includes a washing tub, a motor to rotate the washing tub, and a driving unit to drive the motor, wherein the driving unit includes an inverter to convert direct current (DC) voltage into alternating current (AC) voltage and to output the AC voltage to the motor and 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. Consequently, it is possible to rapidly align a rotor of the motor during the starting operation of the motor.
