Abstract

A heat dissipating fan includes a stator and a rotor. The stator includes a bearing and a winding structure, wherein the bearing is disposed in the winding structure. The rotor includes a fan wheel, a ring-shaped casing and a magnetic member, wherein the ring-shaped casing is disposed in the fan wheel and the magnetic member is disposed in the ring-shaped casing. The fan wheel has an axle inserted into the bearing such that the winding structure is located within the magnetic member. At least one protruding portion protrudes from one side of the ring-shaped casing inwardly and is extended below the winding structure so as to hold the magnetic member and interfere with the winding structure.
