  • Base structure for cooling fan
    Patent number: 9071093
    Abstract: A base structure for cooling fan includes a seat, a circuit board and a motor assembly. The seat has an inner side served as a supporting surface. The circuit board has a first side attached to a top of the supporting surface and an opposite second side having a plurality of electronic elements provided thereon. The motor assembly includes a plurality of stacked silicon steel plates located on the circuit board and above the electronic elements. With the first side of the circuit board being attached to the supporting surface of the seat and the electronic elements on the second side of the circuit board being located in spaces between the motor assembly and the circuit board, more silicon steel plates can be stacked in the motor assembly to enable upgraded motor working efficiency and reduced electric current needed by the cooling fan to operate.
