モータ。 The motor is supported inside the wind body case via support legs at the outer periphery of the end face of its stator cover, and the rotor shaft is rotatably supported at the center of the stator, which is implanted on the outer periphery of the rotor. A plurality of blades are arranged on the intake side of the wind body case, and the inner surface of the wind body case is cylindrical, and the surface facing the blades has a shape in the axial direction so that the inner diameter decreases from the intake side to the discharge side. In a fan motor having a tapered structure, the blade has a taper in the axial direction at the same angle as the wind cylinder case taper so that its radial tip forms a uniform gap with the wind cylinder case inner diameter surface. A fan motor characterized in that the boundary between the front surface and the outer circumferential end surface of the blade and the boundary between the back surface and the outer circumferential end surface are each chamfered to have a semicircular cross section.
