PROBLEM TO BE SOLVED: To provide a fan motor which prevents generation of eddy current loss, generated in a coil yoke and improves efficiency. SOLUTION: In this fan motor 1, a rotor is provided with a shaft 5, a first impeller 2 and a second impeller 3 which are constituted of a magnetic material fixed to both ends of the shaft 5, and a rotor magnet 12 fixed to at least one of the impellers 2, 3. A stator is provided with a substrate 16 which is constituted of nonmagnetic material disposed between the first impeller 2 and the second impeller 3, and coils 6, 7 formed at positions on the substrate 16 which face the rotor magnet 12.
