Patent attributes
A fan rotor mechanism includes a fan impeller, a case and an adhesive body. The fan impeller has a hub and multiple fan blades. The hub has a first top section and a first peripheral section together defining a receiving space for receiving the case. The case has a receptacle for receiving therein at least one magnetic component. The case and the magnetic component define therebetween a filling gap. The case is formed with at least one perforation in communication with the filling gap. The adhesive body is filled up in the filling gap. By means of the structural design of the fan rotor mechanism, the fan rotor mechanism is applicable to various magnetic components with different sizes. Therefore, is unnecessary to manufacture different sizes of molds for different sizes of cases so that the fan rotor mechanism has high universality and is manufactured at lower cost.
