PROBLEM TO BE SOLVED: To provide a fan motor with an axial fan and motor integrated capable of improving blowing efficiency and reducing noises by optimizing design factors for determining performance and noises of the fan such as heights of blades and the fan housing, an inner and outer diameter ratio of the fan, number of the blades, a camber rate, pitch angle, and sweep angle. SOLUTION: This fan motor comprises a hub 53 provided with the motor 51 inside, a plurality of blades 55 attached to the hub 53, a fan housing 57 formed in a form surrounding the blades 55, wherein the blades 55 is positioned higher than the fan housing 57, and in order to increase volume of air sucked by the blades 55, the blades 55 are projected to the outside in the direction of the axis of the fan housing 57, the number of the blades 55 are eight, the inner and outer diameter ratio is 0.40-0.45, and the pitch angle, sweep angle, and camber rate of the blades are formed relatively large.
