Abstract
The invention relates to a high-efficiency energy-saving electric motor with an internal shielding ventilation opening. Multiple ventilation openings are processed on the rear end cap of the fan end of the electric motor. An internal shielding assembly can be embedded in the ventilation openings. Internal and external fans are coaxially installed inside and outside the rear end cap. The forced air cooling system of the overall electric motor is formed by motor fan covers, the internal and external fans and the rear end cap with the inlet and outlet ventilation openings. Compared with another patent technology named "high-efficiency energy-saving electric motor with forced inner circulation heat radiation", temperature rise of operation at full load is reduced for 10K on the basis that other parameters are unchanged or slightly enhanced.
Description
Technical field:
The present invention relates to a kind of high-efficiency energy-saving motor with inner shield ventilating opening.
Background technology:
Modern general AC asynchronous motor, because the heat produced in operation is directly proportional to power, overall temperature rise is reduced for effectively dispersing heat, at the motor that some environment facies use the occasion of cleaning, open type structure is often taked to solve the heat dissipation problem of motor interior, but the motor that most occasion uses, general permission uses open type structure, the air only leaning on wind tooth to stir two ends of rotor space is respectively rotor heat radiation, installing external fan additional in the body one end closed, is whole motor heat radiation.Some large-scale enclosed motors, also have the several ventilating hole channel of processing process on rotor subject, rely on the centrifugal exhaust blower being connected to one end, through the space of special disposal between stator module and motor housing, form inner air forced circulation.Simple way is the shape and size changing or do not change wind tooth as required, a disc deep bead is added in wind tooth tip, form easy centrifugal exhaust blower with the ventilating hole channel of rotor, we call " pressure Inner eycle " this version and have declared national patent " forcing the high-efficiency energy-saving motor of Inner eycle heat radiation ".
Summary of the invention:
Object of the present invention, is the heat-sinking capability of strengthening motor interior, reduces the temperature rise of motor entirety further.
Realize the technical measures of invention, be on the rear end cap of electrical motor fan end, process some ventilating openings, inner shield assembly can be embedded in ventilating opening, inside and outside at rear end cap, the inside and outside fan of coaxial installation.By motor fan housing, inside and outside fan and the band rear end cap into and out of ventilating opening, the air blast cooling system of composition integral motor.
In the motor air blast cooling system of Fig. 1 statement, outside air enters from the air inlet of motor fan cover, and a road drives by external fan centrifugal force, the collection air port formed by the gap of fan housing housing and rear end cap, and guiding body dispels the heat; The wheel disc of external fan is walked around on another road, enters body by the air inlet of rear end cap, in body through internal fan stir circulation after discharge from air outlet.
Air outlet [7] in figure can in the optional position of rear end cap near outer rim.
Can embed the inner shield assembly of ventilating opening, be made up of tube wall and staggered baffle plate, the air complications flowing into inner shield assembly are obstructed by during baffle plate, the larger impurity mixed wherein be blocked in outer not by.Its structure as shown in Figure 2.
The inner shield assembly of ventilating opening can be embedded, the simple mesh structure of single or multiple lift can be reduced to.
Motor rear end plate, and the gap between external fan wheel disc or fan housing housing is all very little, the air inlet of rear end cap is because of the barrier effect of the centrifugal force of exogenous wind pectinid tooth and wheel disc thereof, the stop of air outlet because of fan housing housing and the distinguished and admirable effect in collection air port, at the motor that environment is not too severe applications, the inner shield assembly that ventilating opening is embedded can be omitted.
General common motor two ends of rotor is all with wind tooth, inherently there is the effect of stirring inner air flowing: according to Pa Nuli theorem, the air-flow flowed rapidly in air blast cooling system collection air port, the air in motor body is constantly extracted from the air outlet of rear end cap, as long as well-designed various parameter, just can omit inner fan structure.This way is equal to processes some ventilating openings on the rear end cap of common motor.
We use the structure provided in embodiment, with the assembly of above " air blast cooling system ", when going transformation to declare patent " forcing the high-efficiency energy-saving motor of Inner eycle heat radiation ", by the YC90L-2-3 kilowatt of motor model machine of reequiping, test comparison is carried out with the model machine of the same race do not transformed, prove that the technical program is on other parameter constant or the basis of slightly improving, fully loaded whole motor is run temperature rise and is reduced 10K again.
Accompanying drawing illustrates:
Fig. 1 is the air blast cooling system schematic diagram of motor;
Fig. 2 is the inner shield modular construction schematic diagram embedding rear end cap ventilating opening;
The overall structure schematic diagram that Fig. 3 combines with the motor forcing Inner eycle to dispel the heat for " air blast cooling system ";
Each schematic symbol is unified mark and is described as follows:
1 is the air inlet of motor fan cover; 2 is fan housing housing; 3 is exogenous wind pectinid tooth; 4 is external fan wheel disc; 5 is rear end cap; 6 is rear end cap air inlet; 7 is rear end cap air outlet; 8 for embedding the inner shield assembly of rear end cap inlet and outlet; 9 is motor body; 10 is motor rotary shaft; 11 is internal fan; 12 is the tube wall of inner shield assembly; 13 is the included baffle plate of inner shield assembly tube wall; 14 is motor rotor; 15 is the wind tooth of rotor termination; 16 is deep bead; 17 is front end housing.
Embodiment:
Fig. 3 is the quick circulation for realizing motor interior air, with reference to the structure of patented technology " forcing the high-efficiency energy-saving motor of Inner eycle heat radiation ", the centrifugal exhaust blower structure of rotor one end (actual is exactly that deep bead), turn to the axle stretch end being arranged into motor, " the air blast cooling system of integral motor " in external fan structure alternative costs technology.
Simple description is exactly: in the wind tooth tip of motor rotor shaft extension end, add the rotor that a deep bead forms the centrifugal exhaust blower of band, rear end cap processes ventilating opening, embed inner shield assembly, supporting common external fan and fan housing, namely become the high-efficiency energy-saving motor of complete band inner shield ventilating opening.
Whether rotor core is with ventilation hole, whether rear end cap ventilating opening embeds inner shield assembly, all falls into the protection range of the technical program claim.
