A fan motor driven is provided to reduce manufacturing costs by reducing the number of components and to reduce the thickness of a blade portion and a rotor by mounting the rotor in a hub of the blade portion. A fan motor(100) comprises a stator, a rotor and a plurality of blades(191). The rotor is mounted with a permanent magnet spaced from the stator in a radial direction. The blades are formed in the outer surface of the rotor in a circumferential direction. The blades and the rotor are integrally formed by injection molding.
