    Abstract: A device for driving a plurality of motors and an electric apparatus having the same include a first 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 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 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-phase motor during the multi-phase motor operation.

    Abstract: The present disclosure provides a moving robot including: a body which forms an appearance, a traveler which moves the body, a boundary signal detector which detects a boundary signal generated in a boundary area of a traveling area, and a controller which controls the traveler so that the traveler performs pattern traveling in the traveling area, and when there is an island area in the traveling area, searches for a non-traveling area and controls the traveler so that the traveler continuously performs traveling of the non-traveling area. Accordingly, in a case where the pattern traveling is performed, when there is the island area in the traveling area, continuous traveling is performed by changing a length of the pattern traveling, and thus, the traveling of the traveling area can be completed without stopping the traveling or manually moving the moving robot. Therefore, batter efficiency is improved, and a time of a user and a cost can be reduced.
