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 a traveler so that the traveler performs pattern traveling a plurality of times in the traveling area, and controls the traveler so that a traveling angle during first pattern traveling and a traveling angle during second pattern traveling are different from each other. Accordingly, when the pattern traveling is performed a plurality of times, the pattern traveling is performed at angles different from each other based on a reference axis, and it is possible to minimize an area which cannot be mowed and improve efficiency.

Abstract: A motor assembly includes a shaft configured to form a rotational axis of a motor, a rotor coupled to the shaft, and a plurality of cores provided along the circumference of the rotor and configured to form a magnetic path. The cores are spaced apart from the outer circumferential surface of the rotor by a predetermined distance and configured to surround at least a portion of the outer circumferential surface of the rotor, and each comprise: a pole shoe having a first surface parallel to the radial direction of the rotor; and a pole arm extending from the pole shoe toward the radially outer side of the rotor. Among the plurality of cores, the first surfaces formed on the pole shoes of adjacent cores are symmetrical with respect to the radial direction of the rotor.

Abstract: The present disclosure provides a moving robot including a body which forms an appearance, a traveler which moves the body with respect to a traveling surface in a traveling area, a sensing unit which acquires environment information of the traveling area, and a controller which sets a parameter tailored to the traveling area according to the environment information and performs pattern traveling of the traveling area. Accordingly, even when information on an environment in which the moving robot is installed is not obtained from a manufacture in advance, the moving robot can directly obtain information on the corresponding environment and set an optimum parameter according to the environment to increase efficiency.

Abstract: A device for driving a plurality of motors and an electric apparatus includes a first 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 configured to control the inverter. For starting the single phase motor during operation of the multi-phase motor, the controller is configured to perform, during an alignment period, an alignment of a rotor of the single-phase motor and perform, during a voltage compensation period, a voltage compensation 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.
