An outer rotor type fan structure includes a stator assembly, an outer rotor assembly, a front lateral shielding sheet and an impeller. The stator assembly includes a stator core and a plurality of coils. The outer rotor assembly corresponds to and covers the stator assembly. The outer rotor assembly includes a plurality of magnets and a rotor yoke. The plurality of magnets is disposed corresponding to the plurality of coils. The front lateral shielding sheet is a metallic sheet, the front lateral shielding sheet is disposed between the stator assembly and the outer rotor assembly, and the front lateral shielding sheet corresponds to and covers the plurality of coils. The impeller includes a plurality of blades. The rotor yoke drives the plurality of blades rotating. Thereby, the outer rotor type fan structure can be shielded and the fan can operate properly. |
