The present invention relates to a laundry treatment device having a motor drive device, and this. Motor drive according to an embodiment of the invention the device is, by the switching operation for converting DC power into AC power, and outputting the converted AC power to the motor inverter, and the output current detecting unit for detecting an output current flowing in the motor , on the basis of the output current to be detected, and a control for the inverter control unit, the control unit, and varies the carrier frequency, based on the carrier frequency variable, and varying a voltage command value, based on a variable carrier frequency and the voltage command value and it outputs the inverter switching control signals to the inverter. Accordingly, it is possible to reduce the motor noise during driving.
