Description
Technical field
The present invention relates to the mechanical & electrical technology field, relate in particular to a kind of blower fan, specifically be meant a kind of energy-saving blower fan.
Background technique
Blower fan makes as the general form that adopts a motor driving impeller of a kind of ventilation equipment and forms pressure reduction between intake grill and the exhaust port of blower fan, and then makes the effect current downflow of air at ventilator.Traditional blower fan is then with electric machine external, and the output axle head of motor is coupling and is located at the impeller in the fan casing, and this blower fan is easily manufactured; But because the motor of blower fan is external and the blower fan outside; Therefore there are shortcomings such as volume is big, noise is big, heat dispersion deficiency, particularly in use at some mine ventilators, because of bulky; The installation of blower fan and use be comparatively inconvenience also, also has the big shortcoming of energy consumption in use.
At present; Various New-type electric machines have appearred in continuous development along with motor technology at present, as on electric vehicle, beginning the switching magnetic-resistance disc type electric machine of extensive use at present; It adopts the mode of axial magnetic field to carry out excitation; Dwindled the length of motor greatly, improved efficiency of motor, how combined disc type electric machine with the volume that further dwindles blower fan with blower fan and cut down the consumption of energy a focus that is the blower fan technical development.
Summary of the invention
The technical problem that the present invention will solve is that a kind of new energy-saving blower fan that compact structure, noise are little, energy consumption is low and thermal diffusivity is good is provided.
Technical solution of the present invention is; Following a kind of energy-saving fan at first is provided; Comprise casing, impeller, rotating shaft, intake grill and exhaust port, impeller is installed in interior through rotating shaft; It is characterized in that: the both sides inwall of described casing is provided with the magnetic pole of the stator of a border; The bi-side of impeller are provided with the rotor magnetic pole relative with magnetic pole of the stator, and described magnetic pole of the stator is provided with armature winding and forms axial magnetic field, the magnetic pole radial of described magnetic pole of the stator and rotor magnetic pole relatively and the center of magnetic pole on same cylndrical surface.
After adopting above scheme; The present invention combines switching magnetic-resistance disc type electric machine and blower fan cleverly; The rotor magnetic pole of motor is distinguished on the casing and impeller of built-in and blower fan, and in the present invention, utilized the magnetic field of switching magnetic-resistance disc type electric machine to be axial magnetic field; Make the external diameter of motor increase greatly; The conventional motor of torque ratio is big under with the situation of constant power, has solved required problem than high pulling torque when fan starting (phenomenon of traditional ubiquitous low load with strong power of blower fan) from another point of view, has effectively practiced thrift the energy; In addition; The heat dissipation problem when the present invention places the interior of blower fan can make full use of that thereby airflow flowing has improved motor rotation greatly in the casing in motor; And because motor and blower fan are to place an interior; Save motor case, motor shaft, motor bearings etc. and used material, saved raw material, also avoided the friction noise that produces in the running because of motor bearings and motor shaft on the other hand; And rotor magnetic pole itself also plays the effect of blade in the process of running, when improving ventilation effect, also can effectively reduce wind and make an uproar.Therefore, the present invention has compact structure, noise is little, energy consumption is low and thermal diffusivity is good advantage.
As preferably, described magnetic pole of the stator equates with the external diameter of rotor magnetic pole.This preferred version can improve the excitation effect between magnetic pole of the stator and rotor magnetic pole to greatest extent, makes efficiency of motor maximize.
As preferably, the outer end of described intake grill also is provided with air regulating port, is provided with the air output adjusting vane in the described air regulating port, and described air output adjusting vane threaded shaft is connected between the support that is provided with in the inboard and intake grill of intake grill.Adopt this preferred version, adjustment air regulating port when institute's required airflow is less to keep the balance of intake grill and exhaust port air current flow, also can effectively reduce wind when improving drafting efficiency and make an uproar as required.
As preferably, described support is spherical supports or cylindricality support.This preferred version is convenient to the installation and the use of air output adjusting vane, have simple in structure, the advantage of being convenient to implement.
