Abstract: A salt spray resistant structure of fan motor assembly includes a silicon steel sheet assembly, an insulation support assembly and an encapsulation layer. An inner side of the silicon steel sheet assembly defines a connection hole. A winding assembly is wound on the silicon steel sheet assembly and electrically connected with a circuit board. A first extension section protrudes from the silicon steel sheet assembly into the connection hole to cover a part of the inner side. A bearing cup covers the other part of the inner side. The encapsulation layer encapsulates the insulation support assembly, the winding assembly, the silicon steel sheet assembly and the circuit board so as to achieve salt spray resistant effect.

Abstract: A motor stator structure includes a main body and multiple stopper plates. The main body has multiple magnetic poles and a shaft hole. The magnetic poles outward extend from the main body. Each magnetic pole has a free end outward extending from the main body. The shaft hole passes through the main body between two ends thereof. The stopper plates are respectively correspondingly assembled with the free ends of the magnetic poles. In the motor stator structure, the windings are more densely wound on the magnetic poles to enhance the magnetization efficiency.

Abstract: A rotor magnetic component structure and a fan motor device thereof. The fan motor device includes a stator having a radial magnetic face and a sensor member disposed under the stator. The rotor magnetic component structure includes a main body composed of multiple N poles and multiple S poles, which are alternately arranged. A magnetic force border line is formed between each N pole and each S pole. The magnetic force border line includes a first vertical section corresponding to the radial magnetic face of the stator and an inclined section obliquely extending from a lower end of the first vertical section corresponding to the sensor member. The rotor magnetic component structure is able to reduce the vibration caused in the commutation of the magnetic poles and the sensor member can find the best commutation point.
