Abstract
A stator assembly for an axial-flow fan motor for cooling electronic components consisting of a base, a stator, and insulating pins for connecting the base to the stator. The stator consists of a core covered by an insulating coating and a winding formed thereon from magnet wire. The stator also includes mounting holes formed in the core. The winding is electrically connected to the base through free ends of the magnet wire forming the winding. Each insulating pin has a first conductive end which is mounted to the base and a second non-conductive end which is received in one of the mounting holes on the stator. In the preferred embodiment, the base consists of a printed circuit board which includes circuitry for operating the motor within which the stator assembly is mounted. The method of securing the stator to the base is also disclosed.
