Abstract
This invention relates to a low noise and high efficient motor including a stator, a rotor, an air cover, a fan, a front cover, a shell and a back cover, in which, the rotor is opened with a hole and a high efficient flying wheel is set at the end of the rotor and a stainless steel sheath set outside of the shell to form an air channel in between, in which, heating pieces in the motor are cooled fully and directly since strong gas flows flow through surfaces of the shell, internal part of the rotor and stator, their gas channels and holes on the rotor, and the bearing always works under a low temperature state.
Description
Technical field
The present invention relates to a kind of low-noise high efficiency electric motor, belong to technical field of motors.
Background technology
For a kind of low-noise high efficiency electric motor, its type of cooling and structure are very important.
The product of prior art is an example with the motor of degree of protection IP44/IP54, and its structure comprises fan housing, centrifugal fan, protecgulum, casing, bonnet, stator, rotor.
Behind the electric motor starting, fan leads by fan housing, and wind (air) cools off gelled motor casing appearance, thereby reaches the effect that motor is cooled off.
To the motor of degree of protection IP23, behind the electric motor starting, the acting of epitrochanterian fan blade makes air flows by the open type casing heat be discharged outward, and carries out the inner air and outer air exchange simultaneously, thereby reaches the effect that motor is cooled off.
The problem that above-mentioned motor exists is: after wind (air stream) comes out by fan housing, can spread seriously, make the air-flow guidance quality poor, distribute soon, the wind energy loss is big.
Summary of the invention
The object of the present invention is to provide a kind of low-noise high efficiency electric motor, this motor adopts high efficiency aerofoil fan owing to structurally improve and design, various losses reduce, thereby electric efficiency is improved, and prolong motor useful life, because fan is built-in, noise is low simultaneously.
For achieving the above object, technical solution scheme of the present invention is: this motor comprises loam cake, top chock, upper bearing (metal), lower bearing, efficient fan blade, casing, stator, perforate rotor, stainless steel spacer, pump cover bearing.
Loam cake and outermost stainless steel spacer with screw be connected, stainless steel spacer internal layer is casing, constitute air duct between stainless steel spacer and the casing, the upper and lower side of casing is top chock, pump cover, the internal layer of casing is that stator, bosom are the perforate rotors, efficient fan blade is installed in the top of perforate rotor, bearing is installed, the lower bearing of installation bottom of perforate rotor in the below of efficient fan blade.
During the motor operation, rotor drives efficient fan blade rotation acting, make air form air blast and enter into efficient fan blade by the runner of forming by casing and stainless steel spacer, enter motor internal by the loam cake hole again, go out through orifice flows such as stator and rotor air gap and stator core periphery air channel and rotor core air channels, get back in the air through the pump cover hole.The while air-flow is the hole in the perforate rotor also, flows out to efficient fan blade import, forms air ring.
Beneficial effect of the present invention: because the air draught passage is enclosed construction, and employing low noise efficient fan, the stainless steel spacer is adopted in the casing outside, so general mood flows and electromagnetic noise obtains obvious control, and comparing common ventilated machine noise reduction amplitude is about 10 decibels.
Below in conjunction with drawings and Examples the present invention is made comparisons and to explain.
Description of drawings
Fig. 1 is a low-noise high efficiency electric motor structural representation of the present invention;
Fig. 2 is a low-noise high efficiency electric motor rotor perforate schematic diagram of the present invention.
Embodiment
With reference to Fig. 1, this is a low-noise high efficiency electric motor structural representation of the present invention.
As shown in the figure, this electric machine structure is as follows: loam cake 1 is connected with outermost stainless steel spacer 10 usefulness screws, stainless steel spacer 10 internal layers are casings 7, constitute air duct 11 between stainless steel spacer 10 and the casing 7, the upper and lower side of casing 7 is top chock 3, pump cover 9, the internal layer of casing 7 is that stator 6, bosom are perforate rotors 5, efficient fan blade 1 is installed in the top of perforate rotor 5, and bearing 4 is installed, the lower bearing of installation bottom 8 of perforate rotor 5 in the below of efficient fan blade 1.
With reference to Fig. 2, this is a low-noise high efficiency electric motor rotor open-celled structure schematic diagram of the present invention.
As shown in the figure, open a wind circulation port 12, this hole 12 and stator 6 and rotor 5 air gap channel UNICOMs at rotor upper bearing (metal) place 4.
Described rotor, its hole are opened in the upper end of centre of rotor position, and the below in hole communicates with the air gap of stator, rotor.
Described motor air channel, comprise that electric machine temperature rise is extremely low because air blast, makes that the motor internal heat generating member obtains fully, directly cooling through perforate road on casing surfaces externally and internally, rotor inside and air gap channel thereof, the rotor, hot resistance is low during coil working, electromagnetic performance be improved significantly, simultaneously, the bearing work of remaining on forever under the low-temperature condition, mechanical loss is little, and adopt the efficient axis flow fan, thereby electric efficiency is improved, prolongs motor useful life.
Because the air draught passage is enclosed construction, and adopt the low noise efficient fan, the stainless steel spacer is adopted in the casing outside, so general mood flows and electromagnetic noise obtains obvious control, and comparing common ventilated machine noise reduction amplitude is about 10 decibels.
Though the present invention describes with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is used for illustrating the present invention; should understand and wherein can make variations and modifications and do not break away from the present invention in a broad sense; so be not as limitation of the invention; as long as in connotation scope of the present invention, to the variation of above-described embodiment, the protection range that distortion all will be included claim of the present invention in.
