Abstract
The utility model discloses a motor having small noises comprising a motor housing, a stator, and a rotor. One end of the rotor is connected with a heat dissipation fan, an outer side of which is provided with a fan cover. The fan cover is provided with a silencing device, which comprises, from inside to outside, a disc-shaped baffle plate, an annular-shaped baffle plate, and a ventilating plate. The annular-shaped baffle plate is connected with the fan cover by a rib, and the annular-shaped baffle plate is fixedly connected with the fan cover. The ventilating plate is densely provided with through holes. A diameter of the internal hole of the annular-shaped baffle plate is smaller than a diameter of an excircle of the annular-shaped baffle plate. The motor is advantageous in that the fan cover is provided with the silencing device, and therefore the noises of the motor are small, and the heat dissipation effect cannot be affected by the silencing device.
Description
Technical field
The utility model belongs to machine field, relates in particular to the motor that a kind of noise is little.
Background technology
Existing motor generally all has certain noise, especially uses oneself noise of its radiator fan of motor of a specified duration very big, makes the people sound the sensation that can produce a kind of agitation, affects people's mood.
The utility model content
Large in order to overcome existing motor noise, the utility model provides a kind of simple in structure, New-type electric machine that noise is little.
The utility model solves the technical scheme that its technical problem adopts:
The motor that a kind of noise is little, comprise motor housing, stator and rotor, one end of described rotor is connected with radiator fan, radiator fan is provided with a fan guard outward, described fan guard is provided with silencing means, and silencing means comprises disc-type baffle plate, annular baffle and the ventilative board set gradually from inside to outside, and described disc-type baffle plate is connected with fan guard by rib, annular baffle is fixed on fan guard, on described ventilative board, is densely covered with through hole.
As preferably, the diameter of bore of described annular baffle is less than the outside diameter of disc-type baffle plate.
The beneficial effects of the utility model: the utility model, by be provided with silencing means on fan guard, makes the utility model silencing means in the situation that do not affect radiating effect, has the advantages that noise is little.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The little motor of a kind of noise as shown in Figure 1, comprise motor housing 1, stator and rotor 2, one end of described rotor 2 is connected with radiator fan 3, the outer fan guard 4 that is provided with of radiator fan 3, it should be noted that, described fan guard 4 is provided with silencing means, silencing means comprises disc-type baffle plate 5, annular baffle 6 and the ventilative board 7 set gradually from inside to outside, described disc-type baffle plate 5 is connected with fan guard 4 by rib 8, annular baffle 6 is fixed on fan guard 4, on described ventilative board 7, is densely covered with through hole.
It should be noted that the diameter of bore of described annular baffle 6 is less than the outside diameter of disc-type baffle plate 5.
The utility model by being provided with silencing means on fan guard, the noise that makes motor and fan produce is separated by by disc-type baffle plate and annular baffle and the external world, make the utility model silencing means in the situation that do not affect radiating effect, have the advantages that noise is little.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, those ordinary skill in the art's simple change and replacement are all within protection range of the present utility model.
