Abstract

A fan impeller structure and a manufacturing method thereof. The fan impeller structure includes a hub and multiple securing sections. The hub has a top section, an annular section and multiple recesses. The annular section axially extends from a circumference of the top section. The annular section and the top section together define a receiving space. The recesses are formed at a junction between the top section and the annular section. The securing sections are disposed in the receiving space and formed oppositely between the recesses. The manufacturing method of the fan impeller structure enables the manufacturing process to be simplified. Moreover, by using the securing sections, magnetic members can be quickly connected with and secured to inner circumference of the hub to save working time.
