Abstract:
A laundry treatment machine includes a drum, a motor to rotate the drum, 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 an alignment current to the motor so as to align the motor during a starting operation of the motor and to supply a torque current for rotating the motor to the motor together with the alignment current after the motor is aligned. Such a laundry treatment apparatus prevents a reverse rotation phenomenon of the drum due to load.
