Abstract
A fan motor with an improved inhaling structure so as to enhance ventilation efficiency and performance, as well as cooling performance. An outer housing member has a respective face opposite to a drive unit . An intake hole of an arbitrary diameter is provided in a first face of the outer housing member , while another intake hole of an arbitrary diameter is provided in a second face thereof. Thus, a substantial amount of air is taken in from the two faces of the outer housing member , thereby drastically improving the ventilation efficiency. Even though an inhaling passage is not ensured substantially on a top face of the outer housing member , the air is able to be inhaled even through a slight clearance due to the other intake hole , thus improving the cooling performance. The air taken in from the intake holes and of the outer housing member is smoothly discharged toward the exhaust direction of a fan , without striking on walls of a casing and a cover
