Abstract: Embodiments of the invention provide an electric blower, including a diffuser having a cover and an impeller sequentially disposed at one side in a shaft direction thereof, a front disposed at the other side in the shaft direction of the diffuser, and an elastic body mounted between the front and the diffuser to support the diffuser.

Abstract: Embodiments of the invention provide an impeller for an electric blower including an upper plate integrated with a blade portion which is provided with a coupling protrusion, and a lower plate provided with a coupling hole corresponding to the coupling protrusion of the blade portion. The upper plate integrated with the blade and the lower plate are made of a thermoplastic resin, and the coupling protrusion of the blade portion is inserted into the coupling hole of the lower plate and is fused and fixed.

Abstract: Embodiments of the invention provide an impeller for an electric blower. The impeller includes a hub and a shroud disposed to correspond to the hub so that an internal space and an outlet are formed between the hub and the shroud and including an inlet formed therein to introduce air and a disk part formed from the inlet toward an outside. The impeller further includes a blade disposed in the internal space between the shroud and the hub, whereby a distance from a leading edge of the blade positioned at the inlet side to the center of the inlet is the same as a minimum distance from a rim of the inlet to the center of the inlet.

Abstract: Disclosed herein is a fan module including an impeller cover having an intake member formed therein and covering one side of a housing, an impeller accommodated within the impeller cover and rotatably coupled to a rotational shaft of a motor accommodated in the housing, and a leakage reduction member positioned in an inner surface of the impeller cover to reduce a flow leakage between the impeller cover and the impeller.

Abstract: Disclosed herein is a switched reluctance motor assembly, including: a rotating shaft forming a rotating center of a motor; a rotor part rotatably coupled on the rotating shaft; a front part mounted over the rotor part to support a first bearing part of the rotating shaft; a diffuser part having a plurality of integrated guide vanes mounted at an outer side thereof while being coupled with the axial upper portion of the front part; and an impeller part coupled with the axial upper portion of the diffuser and coupled with the rotating shaft. According to the preferred embodiments of the present invention, it is possible to reduce the noise generated at the time of driving the motor by manufacturing the guide vanes mounted in the diffuser of the switched reluctance motor so as to be vertically integrated.

Abstract: Disclosed herein is a switched reluctance motor comprising: an outer rotor provided with a plurality of salient poles protruded at equidistance along an inner peripheral surface thereof; and a stator provided in the outer rotor, including a plurality of stator cores including a pair of stator salient poles protruded toward the salient pole of the outer rotor and a stator yoke connecting and supporting stator salient poles to each other, and having phase windings in which coils are wound around the stator salient poles, wherein a magnetic flux generated by applying a current to the phase winding flows through the pair of stator salient poles and the salient pole of the outer rotor.
