Abstract
A fan motor includes a pair of fans axially mounted to both sides of a rotary shaft of the motor. The motor includes an inner rotor placed inside a stator wound with windings and an outer rotor placed outside the stator. The motor thus has a dual-rotor structure where the inner rotor and the outer rotor are held such that both the rotors can rotate on the rotary shaft.
