Abstract: A device for driving a plurality of motors and an electric apparatus having the same include a first 5 capacitor and a second capacitor; an inverter connected to a DC terminal; a multi-phase motor connected to the inverter; a single-phase motor serially connected with the multi-phase motor; and a controller to control the inverter, wherein, for 10 starting the single phase motor during operation of the multi-phase motor, the controller controls to perform an alignment period for alignment of a rotor of the single-phase motor and a voltage compensation period for compensating a voltage change of a DC 15 terminal neutral point between the first capacitor and the second capacitor based on the alignment of the rotor of the single-phase motor. Accordingly, it is possible to stably start the single-phase motor while reducing the rotational torque ripple of the multi 20 phase motor during the multi-phase motor operation. 220x 420a 420b 420c 420d INVERTER INVERTER INVERTER [INVERTER Ma Mb Mc Md COMPRESSOR DRUM FAN PUMP MOTOR M OTOR MOTOR MOTOR

Abstract: The present disclosure provides a control method capable of, by using a current value of a nozzle, determining whether a nozzle is separated from a vacuum cleaner and whether the nozzle is reconnected to the vacuum cleaner after separation. To this end, a vacuum cleaner may comprise a nozzle connectable to a suction unit for suctioning dust. The nozzle may comprise a rotary cleaning unit for applying pressure to a cleaning target surface so as to separate a foreign substance therefrom, and a nozzle motor for driving the rotary cleaning unit. In order to drive the nozzle, a voltage having been controlled by a pulse width modulation (PWM) method is applied, and a measurement unit included in the vacuum cleaner may measure a current value of the nozzle, the current value depending on the applied voltage.

Abstract: The present invention relates to a washing machine, and more specifically to a drum washing machine allowing a tub to be easily cleaned, and to a method for cleaning the tub of the drum washing machine. To that end, the present invention, with respect to a method for controlling a washing machine comprising washing and rinsing cycles, provides a method for controlling the washing machine comprising: a first water supplying step for supplying washing water to the interior of a tub while a drum is rotating at a water-supplying RPM; and a first wash step, executed following the completion of the first water supplying step, for accelerating the rotation of the drum from the water-supplying RPM to first-wash RPM so that a circulatory flow is created in which the washing water falls from the top of both ends of the tub while circulating along the inner circumferential surface of the tub due to the rotational power of the drum.
