Claims

[Scope of Claim for Utility Model Registration] A stator having a stator core with an approximately rectangular outer shape, and a cylindrical portion located at the opening edge of one end of the cylindrical portion housing the rotor disposed inside the stator. an air passage formed between a case main body having an annular flat part projecting outward from the cylindrical part, an inner surface of the cylindrical part, and an outer surface of the stator core having a corner part closely disposed on the inner surface of the cylindrical part; , a case end plate fixed to the annular plane part and having a bearing support part in the center; a centrifugal fan attached to the rotor shaft of the rotor passing through the bearing support part; and the annular plane part. It has a plurality of air inlets and a wind introduction slanted wall that gradually approaches the annular plane part toward the air inlets, and has a plurality of rectifying air channels connected to the air inlets on the inner surface. A rectifying disk made of synthetic resin is formed between the centrifugal fan and the opening at one end of the case body, and is disposed to cover the opening at one end; and a fan cover attached to an opening edge of one end of the case body to cover the centrifugal fan, the rectifying circle facing the inner surface of the fan cover across the wind introduction slanted wall. Along the board wind introduction wall,
At the connection between the wind introduction wall and the wind introduction slanted wall, there is provided an air guide groove whose inlet is located on the circumferential wall of the rectifying disc that is in contact with the inner surface of the fan cover, and whose outlet communicates with the air inlet. An electric blower characterized by the following:
