Abstract
A fan includes a metal plate, multiple cylindrical coils, a frame and an impeller. Multiple teeth annularly arranged and connected with each other are formed on the metal plate. Each cylindrical coil is arranged between adjacent teeth, and each end of the cylindrical coil is arranged toward corresponding tooth. The frame is arranged on a surface of the metal plate and extended along an edge of the metal plate. A flow channel and an air outlet connected to the flow channel are formed by the frame. The impeller is arranged in the flow channel. A stator structure of the fan is simplified by forming the teeth on the metal plate.
