    摘要： The present invention relates to a motor assembly comprising a core with an improved structure. An embodiment of the present invention provides a motor assembly comprising: 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.

    摘要： The present disclosure provides a control method for automatically detecting what kind of nozzle is a nozzle mounted on a cleaner by using different starting current profiles. The cleaner may include a suction unit for suctioning dust, and various nozzles which are detachable from the suction unit. The nozzle may include a rotation cleaning unit which is accommodated in the nozzle to clean a surface to be cleaned, and a nozzle driving unit for driving the rotation cleaning unit. The nozzle may exhibit different starting current profiles depending on the number of rotations or reduction ratio of the nozzle driving unit, or whether an auxiliary control unit is included.

    摘要： Disclosed is a washing machine comprising a main drum rotatably mounted in the tub, a sub drum mounted inside the main drum to be relatively rotatable with respect to the main drum, an outer shaft for rotating the main drum, an inner shaft for rotating the sub drum and disposed inside the outer shaft, and a driving motor. The driving means is configured to rotate the main drum and the sub drum in different directions and/or with different rotational speeds. The washing machine further comprises a main drum spider to connect the main drum to the outer shaft to transfer a driving force of the driving means to the main drum, and a sub drum spider to connect the sub drum to the inner shaft to transfer a driving force of the driving means to the sub drum, wherein the two spiders are arranged to be independently rotatable.
