    Abstract: A motor includes: an inner housing defining an accommodation space, an outer housing defining a flow path with the inner housing, an impeller disposed at a first side of the inner housing, a power portion that is disposed in the accommodation space and that includes a rotation shaft coupled to the impeller so as to be rotated together with the impeller, a bracket coupled to the inner housing at a second side of the inner housing and rotatably supporting the rotation shaft, and a printed circuit board (PCB) that is spaced apart from the bracket by a predetermined distance and that is electrically connected to the power portion. A circumference of the PCB includes a plurality of concave portions that are spaced apart from each other, and the plurality of concave portions are recessed toward a center of the PCB.

    Abstract: An electric motor assembly includes an outer housing with two sides open, an impeller provided in the outer housing, an inner housing disposed concentrically in the outer housing and spaced apart from the impeller, a stator provided in the inner housing, a rotor rotatably disposed in the stator, a first air flow path through which air flows in an axial direction between the inner housing and the outer housing based on rotation of the impeller, and a second air flow path through which air is joined with the air of the first air flow path via an inside of the inner housing and a gap between the impeller and the inner housing based on rotation of the impeller. Accordingly, cooling of the stator can be facilitated by the air flow paths.

    Abstract: A motor includes a stator and a rotor. The rotor includes: a plurality of rotor core segments arranged along a circumferential direction of the rotor on the inner side or the outer side of the stator and spaced apart from one another to define a plurality of permanent magnet arrangement slots between the plurality of rotor core segments; a plurality of permanent magnets inserted into the plurality of permanent magnet arrangement slots, respectively; a first frame that couples the plurality of rotor core segments to the plurality of permanent magnets, the first frame being made of a first material; and a second frame that surrounds the plurality of rotor core segments, the plurality of permanent magnets, and the first frame and that couples the plurality of rotor core segments, the plurality of permanent magnets, and the first frame to one another. The second frame is made of a second material different from the first material.

    Abstract: A motor including a stator includes a first stator core, and a second stator core that is independent from the first stator core and that is symmetric to the first stator core with respect to a vertical line that passes through a center of the stator. Each of the first and second stator cores includes a yoke, a center tooth that extends from a center of the yoke toward the center of the stator, and outer teeth that extend from a first end of the yoke and a second end of the yoke, respectively. The center tooth is located between the outer teeth, and a length of the outer teeth is greater than a length of the center tooth.

    Abstract: A display device that includes a housing with at least one Printed Circuit Board (PCB) and a plurality of rollers disposed in the housing. The display device also includes a display unit which, in turn, includes a display panel and a module cover. The display device further includes a driving unit that is connected to the display panel and the module cover. The driving unit moves the display panel and the module cover between a first state and a second state. In the first state, the panel and module cover are wound around at least one of the plurality of rollers, and in the second state they are unwound from the at least one of the plurality of rollers and exposed by being drawn out from the housing.

    Abstract: A display device is disclosed. The display device includes: a housing; at least one roller configured to be positioned within the housing; a display portion including a display panel and a module cover; and a telescopic bar, one end of which is fixed to the interior of the housing and the other end is fixed to the bottom end of the display portion, wherein the display panel and the module cover are either in a first state where the display panel and the module cover are kept wound around the at least one roller or in a second state where the display panel and the module cover are kept unwound from the at least one roller, in contact with each other, and exposed out of the housing. The telescopic bar supports the back of a display portion in conjunction with the display portion, thereby allowing the display portion to remain flat.
