Abstract: Disclosed herein are a motor driving apparatus (220) and a laundry treatment machine (100) including the same. The motor driving apparatus (220) includes an inverter (420) to convert a direct current (DC) voltage into an alternating current (AC) voltage and to output the AC voltage to the motor (230), an output current detector (E) to detect output current flowing in the motor (230), a filter (570) to filter the detected output current, and an inverter controller (430) to control the inverter (420). The inverter controller (430) outputs an inverter switching control signal based on high-frequency signal injection, estimates a position of a rotator of the motor (230) based on the filtered output current and a delay compensation value for compensating for filtering delay of the filter (570), and outputs the inverter switching control signal based on the estimated position, thereby compensating for a delay error due to the filter (570) upon position estimation through high-frequency signal injection in a sensorless method.
