    Abstract: Disclosed herein are a motor driving apparatus (220) and a home appliance including the same. The motor driving apparatus (220) and the home appliance include an inverter (420) to convert a direct current (DC) power into an alternating current (AC) power through a switching operation and to output the converted AC power to a motor (230), an output current detector (E) to detect an output current flowing through the motor (230), a controller (430) to control the inverter (420), wherein, during a first interval after the motor (230) stops, the controller (430) controls a phase current of a predetermined frequency to flow through the motor (230) to estimate a position of a rotor of the motor (230), and estimates the position of the rotor of the motor (230) based on the detected output current while the phase current of the predetermined frequency flows through the motor (230). Thereby, the sensorless motor driving apparatus (220) can easily estimate the position of the motor rotor.

    Abstract: The present disclosure relates to a drain pump driving apparatus and a laundry treatment machine including the same. A drain pump driving apparatus according to an embodiment of the present disclosure includes a controller configured to drive a motor, during drainage, based on an output current and a direct current (DC) terminal voltage with a first power when a lift is at a first level and to drive the motor with the first power when the lift is at a second level that is greater than the first level, wherein the lift is a difference between a water level of a water introduction part through which water flows into a drain pump and a water level of a water discharge part through which the water is discharged out of the drain pump. Accordingly, water pumping can be performed smoothly even if the lift is changed during the drainage.
