Description
Technical field
The utility model relates to machine field, particularly a kind of brshless DC motor.
Background technology
Brshless DC motor is made up of motor body and driver, is a kind of typical electromechanical integrated product.Brushless electric machine refers to the motor of brushless and commutator (or collector ring), also known as commutatorless machine.As far back as 19th-century birth motor time, the practicality motor of generation is exactly brushless form, i.e. mouse cage AC formula asynchronous motor, this motor is widely used.But asynchronous motor has many defects that cannot overcome, so that motor technology slower development.The middle of last century has been born transistor, thus adopts transistor commutating circuit to replace the DC brushless motor of brush and commutator just to arise at the historic moment.This Novel brushless motor is called electronically commutated direct current machine, which overcomes the defect of first generation brushless electric machine.
Control board is the key component of brshless DC motor, in the course of work, can not be subject to electromagnetic interference, can not be overheated.Control board, once be interfered, will cause motor normally to run.And if control board occurs overheated, performance will decline, and motor sometimes also can be caused normally to run, and time serious, control board also can be caused directly to be burned.In order to avoid electromagnetic interference and overheated, current way allows control board away from motor body, and namely control board is independently arranged relative to motor body.But so, the structure of motor is compact not, volume is comparatively large, cannot apply in some field.
Utility model content
The purpose of this utility model is, provides a kind of brshless DC motor.This brshless DC motor not only compact conformation, volume is little, and suitable application area is wide, and in the course of work, control board can not be subject to electromagnetic interference, and it is overheated also can not to occur, and can ensure that motor normally works.
The technical solution of the utility model: brshless DC motor, comprise casing, the both sides of casing are respectively equipped with front end housing, the rear end cap of band gas channel, and the inside of casing is provided with mutually corresponding stator, rotor and rotating shaft, and the interior sidewall surface of described front end housing is provided with roughing efficiency air filter; The outer side surface of described rear end cap is provided with high efficiency particulate air filter, and the inner webs face of described rear end cap is provided with soleplate, is arranged on the control board on soleplate and soleplate is formed to the metallic shield guard surrounded; In described rotating shaft, between front end housing and rotor, be provided with wind wheel.
In aforesaid brshless DC motor, described roughing efficiency air filter is nylon filter; Described high efficiency particulate air filter is the efficient filter screen of V-BED.
In aforesaid brshless DC motor, described wind wheel has 10 with blade.
In aforesaid brshless DC motor, described wind wheel has 10 blades.
In aforesaid brshless DC motor, the material of described metallic shield guard is copper.
Compared with prior art, control board, by adopting new structure, is arranged on motor body inside by the utility model, and metallic shield guard is set avoids control board to be subject to electromagnetic interference, between front end housing and rotor, arrange wind wheel dispel the heat, prevent control board from occurring overheated, disclosed brshless DC motor not only compact conformation, volume is little, suitable application area is wide, and in the course of work, control board can not be subject to electromagnetic interference, also it is overheated to occur, and can ensure that motor normally works.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-casing, 2-front end housing, 3-rear end cap, 4-stator, 5-rotor, 6-rotating shaft, 7-roughing efficiency air filter, 8-high efficiency particulate air filter, 9-soleplate, 10-control board, 11-metallic shield guard, 12-wind wheel.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.Brshless DC motor, forms as shown in Figure 1, comprises casing 1, and the both sides of casing 1 are respectively equipped with front end housing 2, the rear end cap 3 of band gas channel, and the inside of casing 1 is provided with mutually corresponding stator 4, rotor 5 and rotating shaft 6.Be characterized in: the interior sidewall surface of described front end housing 2 is provided with roughing efficiency air filter 7; The outer side surface of described rear end cap 3 is provided with high efficiency particulate air filter 8, and the inner webs face of described rear end cap 3 is provided with soleplate 9, is arranged on the control board 10 on soleplate 9 and soleplate 9 is formed to the metallic shield guard 11 surrounded; In described rotating shaft 6, between front end housing 2 and rotor 5, be provided with wind wheel 12.
Described roughing efficiency air filter 7 is nylon filter; Described high efficiency particulate air filter 8 is the efficient filter screen of V-BED (V-type Wind Volume high efficiency particulate air filters).Described wind wheel 12 (wind wheel 12 is made up of wheel hub and the blade be arranged on wheel hub) has 10 with blade.As preferably, described wind wheel 12 has 10 blades.The material of described metallic shield guard 11 is copper, and namely metallic shield guard 11 is formed by proof copper-wire braided.
Below to related description of the present utility model
Roughing efficiency air filter 7, for filtering 5 μm with dust particles, prevents the dust particle in air from falling into motor internal, causes damage to motor.High efficiency particulate air filter 8, for filtering the particle dust of more than 0.5um, prevents particle dust to be inhaled into motor internal, causes damage to motor.
The effect of metallic shield guard 11 is the interference preventing control board 10 to be subject to electromagnetic signal, ensures that motor normally works.During machine operation, wind wheel 12 rotates with rotating shaft 6, constantly the gas channel of the hot-air of casing 1 inside on front end housing 2 is discharged, make the air pressure of casing 1 inside lower than external pressure, like this, outside cold air will constantly pour in casing 1 inside by the gas channel on rear end cap 3, accelerates heat radiation, prevents control board 10 from occurring overheated.Research finds, is arranged on by wind wheel 12 between front end housing 2 and rotor 5, not only can ensure that heat radiation is good, and when starting, the vibration caused is less; Wind wheel 12 have 10 with blade time, performance is better, and when especially having 10 blades, performance reaches best, causes vibration hardly.
