摘要： 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.

摘要： The present disclosure relates to a motor driving device and a laundry treatment apparatus. The motor driving device may include an inverter to convert DC power into AC power according to a switching operation and to output the converted AC power to a motor, an output current detector to detect an output current flowing through the motor, and a controller to control the inverter based on the detected output current. The controller changes a carrier frequency, changes a voltage command based on the changed carrier frequency and outputs an inverter switching control signal to the inverter based on the changed carrier frequency and the changed voltage command. Accordingly, noise may be reduced during operation of the motor.
