Abstract
A fan motor includes a stationary portion, a rotary portion, and an impeller. The rotary portion is configured to rotate about a center axis with respect to the stationary portion through a bearing mechanism. The impeller is configured to rotate together with the rotary portion. The stationary portion includes an armature including a coil positioned around the center axis, a metal base plate arranged below the armature, and a circuit board located above or below the base plate and provided with a lead wire electrically connected to the outside. The base plate and the lead wire are isolated from each other by a protection member. By installing the protection member between the metal base plate and the lead wire, the lead wire is prevented from making direct contact with the inner peripheral edge of the metal base plate.
