In order to make the purpose of this utility model, technical scheme and advantage clearer, by the following examples, and tie
Close accompanying drawing, electric equipment of the present utility model, fan structure and fan electromotor are further elaborated.Should be appreciated that
Specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Seeing Fig. 1 and Fig. 2, this utility model provides a kind of fan electromotor 110, and fan electromotor 110 is installed on fan knot
In the fan blade 120 of structure 100.Fan electromotor 110 of the present utility model is be applicable to the fan structure 100 with fan blade 120.Wind
Operationally, fan blade 120 can produce air-out to fan structure 100, the reverse air-out pulling force that now fan blade 120 is brought by air-out,
And then make fan blade 120 produce the displacement along air-out direction of pull.Fan electromotor 110 of the present utility model can produce and air-out
The magnetive attraction that direction of pull is contrary, reduces the fan blade 120 displacement along air-out direction of pull, it is ensured that fan electromotor 110 runs well,
Reduce noise.
In this utility model, fan electromotor 110 includes a support component 111, rotating shaft 112, rotor assembly 113 and magnetic part
114.Prop up support component 111 and be used to passive.Rotor assembly 113 is used to install fan blade 120.Prop up support component 111
Including block bearing 1111 and mounting bracket 1112, mounting bracket 1112 offering installing hole, block bearing 1111 is installed on
In installing hole.Rotating shaft 112 is rotatably installed in block bearing 1111.Rotor assembly 113 is relative with mounting bracket 1112 to be set
Being placed in rotating shaft 112, rotor assembly 113 drives rotating shaft 112 and fan blade 120 to rotate.Magnetic part 114 is arranged at mounting bracket 1112
In, and the end setting of the corresponding rotating shaft 112 of magnetic part 114.Magnetic part 114 can produce the magnetive attraction of absorption rotating shaft 112, and magnetic
Air-out pulling force when the direction of property power rotates with fan blade in opposite direction.
Operationally, rotor assembly 113 can drive rotating shaft 112 and fan blade 120 together to rotate to fan electromotor 110.Now,
Fan blade 120 can produce air-out so that fan blade 120 is by the air-out pulling force effect contrary with air-out direction.In the present embodiment, wind
Leaf 120 is directed towards the right direction air-out shown in Fig. 1, and produces a counteracting force contrary with air-out direction, and this is anti-
Active force is air-out pulling force.Air-out pulling force can drive fan blade 120, rotor assembly 113 and rotating shaft 112 along the direction of air-out pulling force
Motion, and then the cooperation of fan electromotor 110 is had problems.Therefore, fan electromotor 110 of the present utility model is in rotating shaft 112
End increase magnetic part 114, by magnetic part 114 produce absorption affinity with offset fan blade 120 air-out pulling force, it is to avoid fan blade
