Switched reluctance motor assembly

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.

What is claimed is: 
     
         1 . A switched reluctance motor assembly, comprising:
 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 coupled 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 part and coupled with the rotating shaft.   
     
     
         2 . The switched reluctance motor assembly of  claim 1 , further comprising:
 a housing enclosing an outer side of the rotor part and formed to include a first bearing part and a second bearing part coupled of bottom of the rotor part; and   a cover member coupled with the axial upper portion of the housing to cover the diffuser part and the impeller part.   
     
     
         3 . The switched reluctance motor assembly of  claim 1 , wherein the guide vane is formed to guide air sucked by the impeller part into the motor. 
     
     
         4 . The switched reluctance motor assembly of  claim 1 , wherein the guide vane is protruded outwardly in a circumferential direction in a form in which an upper portion of the guide vane encloses the impeller part. 
     
     
         5 . The switched reluctance motor assembly of  claim 1 , wherein the guide vane is protruded so as to be inclined axially downwardly in a state in which a lower portion of the guide vane is connected with an upper portion thereof. 
     
     
         6 . The switched reluctance motor assembly of  claim 1 , wherein a connecting part that connects an upper portion of the guide vane with a lower portion thereof forms a curved surface. 
     
     
         7 . The switched reluctance motor assembly of  claim 6 , wherein the guide vane has an inner side extending axially downwardly from the inner side of the connecting part and formed in a curved surface to guide a flow of sucked air axially downwardly. 
     
     
         8 . The switched reluctance motor assembly of  claim 1 , wherein a flow of air flowing out along the upper portion of the guide vane continuously flows in the axial lower portion thereof through a connecting part. 
     
     
         9 . The switched reluctance motor assembly of  claim 1 , wherein the diffuser part includes:
 a disk-shaped diffuser body coupled over the rotating shaft;   an upper guide vane protruded over an outer circumferential surface of the diffuser body; and   a lower guide vane integrally formed with the lower portion of the upper guide vane.   
     
     
         10 . The switched reluctance motor assembly of  claim 9 , wherein the number of upper guide vanes and the number of lower guide vanes are the same. 
     
     
         11 . The switched reluctance motor assembly of  claim 9 , wherein the diffuser part further includes a connecting guide vane disposed at a connecting part extending axially from the upper guide vane and the lower guide vane. 
     
     
         12 . The switched reluctance motor assembly of  claim 11 , wherein the connecting guide vane is connected with the lower guide vane while an outer side of the connecting guide vane contacts an outer diameter of the upper guide vane. 
     
     
         13 . The switched reluctance motor assembly of  claim 11 , wherein a point where an inner surface of the connecting guide vane meets an extension of the lower guide vane is formed in a curved surface to continuously guide a flow of air. 
     
     
         14 . The switched reluctance motor assembly of  claim 9 , wherein air flowing out along the upper guide vane continuously flows through the connecting guide vane and flows in the lower guide vane.
