Abstract

A moistureproof fan motor comprises a frame. A fixing seat, a stator component and a rotor component are arranged in the frame; a bushing is arranged in the middle of the fixing seat in a vertical extending manner, ball bearings are respectively arranged on two inner sides of the bushing, a mandrel of the rotor component penetrates the inner hole of the bushing to be rotatably borne on the ball bearings, the stator component is fixed on the outer periphery of the bushing, and the rotor component further comprises an opening frame integrally connected on the mandrel and encloses the rotator component from the outer side; the stator component comprises a lower shell, an upper shell, a circuit board and a stator, the lower shell if of a circular ring structure provided with a middle hollow hole, the circuit board is located in the lower shell and is covered with a protecting layer, and the protecting layer is made of silica gel. The moistureproof fan motor is simple in structure and convenient to install, the effective sealing effect is provided, damage to circuit elements by moisture and the like is avoided, service life is prolonged, and maintenance cost is lowered.

Description

technical field [0001] The invention relates to a moisture-proof fan motor. Background technique [0002] With the continuous application of computers, the role of fan motors for cooling computer chips is becoming more and more obvious. However, due to the complex application environment of computers, which are often in humid working environments, electronic components such as circuit boards in fan motors are susceptible to damage. The influence of humidity and damp fog can cause damage to the fan motor. [0003] For this reason, in view of the above-mentioned defects, the designer of the present invention researches and designs a kind of moisture-proof fan motor to overcome the above-mentioned defects by concentrating on research and design, and integrating experience and achievements in related industries for many years. Contents of the invention [0004] The technical problem to be solved by the present invention is: due to the complex application environment of the co...
