Benefits of technology

The present invention is a switched reluctance motor assembly designed to improve the flow of air passing through a diffuser by integrating guide vanes vertically. This reduces noise during operation.

Problems solved by technology

However, vibration or noise may occur at the time of driving the switched reluctance motor (SRM).
In particular, since the vacuum cleaner using the switched reluctance motor (SRM) requires a high suction power, a flow noise generated from the switched reluctance motor (SRM) may be very large.
However, the guide vanes that are each mounted over and under the diffuser as described above hinder the air flow from constantly flowing and disperse the air flow, such that the air flow generated from above the diffuser is dispersed while moving down, thereby increasing loss and noise.

Embodiment Construction

[0035]The objects, features and advantages of the present invention will be more clearly understood from the following detailed description of the preferred embodiments taken in conjunction with the accompanying drawings. Throughout the accompanying drawings, the same reference numerals are used to designate the same or similar components, and redundant descriptions thereof are omitted. Further, in the following description, the terms “first,”“second,”“one side,”“the other side” and the like are used to differentiate a certain component from other components, but the configuration of such components should not be construed to be limited by the terms. Further, in the description of the present invention, when it is determined that the detailed description of the related art would obscure the gist of the present invention, the description thereof will be omitted.

[0036]Hereinafter, preferred embodiments of the present invention are described in detail with reference to the accompanying...

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.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 10-2012-0134788, filed on Nov. 26, 2012, entitled “Switched Reluctance Motor Assembly” which is hereby incorporated by reference in its entirety into this application.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]The present invention relates to a switched reluctance motor assembly.[0004]2. Description of the Related Art[0005]Generally, a switched reluctance motor (SRM) called an SR motor has a structure in which both the stator and the rotor have a magnetic structure that is a salient, the stator is wound with a concentrated type coil, and the rotor is configured of only an iron core without any excitation device (winding or permanent magnet) and therefore, has an excellent competitive price.[0006]In detail, the switched reluctance motor (SRM) uses a reluctance torque depending on a change in magnetic reluctance to rotate a rotor and therefore, has low manufac...
