Abstract
A fan motor with an increased amount of air drawn in toward fan blades so as to obtain a desirable airflow characteristic. A fan motor includes a rotor and a plurality of fan blades provided radially therefrom. Each fan blade is provided with an air intake part on a proximal side and a radial part on a distal side, including a first front surface on the former side and a second front surface on the latter side. The first and second front surfaces have different curvatures. Thus, air F can be impelled out toward a perimetric direction, and at the same time the intake of air toward the fan blades is promoted. Accordingly, the amount of air to be drawn in toward the fan blades is increased, thereby obtaining desirable airflow characteristic.
