1. A salt spray resistant structure of fan motor assembly, comprising:
a silicon steel sheet assembly having an upper side and a lower side and an outer side and an inner side connected between the upper and lower sides, the inner side circularly defining a connection hole;
an insulation support assembly including an upper insulation support and a lower insulation support, the upper and lower insulation supports being respectively disposed on the upper and lower sides of the silicon steel sheet assembly, a winding assembly being wound on the upper and lower insulation supports and electrically connected with a circuit board, a first extension section protruding from one side of the upper insulation support into the connection hole to cover a part of the inner side; and
an encapsulation layer integrally encapsulating the insulation support assembly, the winding assembly, the silicon steel sheet assembly and the circuit board, the first extension section and the inner side, which are not encapsulated by the encapsulation layer, being fitted with a bearing cup, an outer side of the bearing cup directly covering the other part of the inner side.
