Abstract
An eccentric rotor equipped with a fan is included in an axial gap micro-fan motor for generating vibrations and cooling. The rotor has a first impeller section having a low specific gravity and a second impeller section having a high specific gravity. Each fan comprises a flat section at an upper surface of an axial gap magnet and an impeller section at a side of the magnet. The fans are assembled by concave-convex mating sections at the flat sections and are also bonded to and held by the axial gap magnet. Impeller blades of the fans are optionally formed as backward vanes.
