Abstract
A three-phase stator structure includes a plurality of laminated substrates, each of which is provided with a tracing layer, a plurality of through holes, and a plurality of electrical connection vias. The tracing layer consists of a plurality of induction coils, which are respectively arranged around an outer side of one of the through holes. The electrical connection vias are internally provided with an electrically conducting material, with which the induction coils on one substrate can be extended and electrically connected to the induction coils on an adjacent substrate. Every through hole has a metal rod inserted therein to enable upgraded magnetic force of the induction coils. A fan using the three-phase stator structure is also disclosed. With the three-phase driven stator structure, the fan can be slimmed while maintain good inductive-excited magnetic force and accordingly, high rotational speed and sufficient air volume.
