Abstract

A three-phase brushless fan is disclosed. In the three-phase brushless fan, an outer shell member includes an axis part, and winding columns are disposed around the axis part, and the rotating module includes a fan, an axis coupling part pivoted to the axis part, and a magnetic element having south and north magnetic portions; a circuit board electrically connected to coils formed by winding a conductive wire on the winding columns. The number of the coils is three or a multiple of three, and the number of the coils is not equal a total amount of the south and north magnetic portions. As a result, winding the conductive wire to form the multiple coils can omit the operation of placing coils on the circuit board and save labor cost in welding two head ends of conductive wires on the circuit board one by one.
