In order to achieve the above object, the technical solution of the utility model has been to provide a kind of electric motor winding end wind path packed configuration, it is characterized in that: comprise the wind blocking cylinder or the excessive plate that are positioned at stator coil top, deep bead top and wind blocking cylinder or excessively plate are closing, and bottom and the stator coil end of deep bead are tightly connected;
The every end of stator coil end inner circle is laid an air guide ring, and air guide ring and stator coil are smeared curing with door and window with sealing neutral silicone resin one.
Preferably, adjacent two stator coil hypotenuse gaps are by conformal felt two fillings, and gap between each stator coil end upper strata Bian Yu lower floor limit, at filling conformal felt two places, fills with conformal felt one circumference by inner side unshakable in one's determination, and fill with polyester adhesive-bonded fabric one circumference in outside;
Polyester adhesive-bonded fabric two fillings for the nose of each stator coil.
The gap of preferably, being filled between described air guide ring and described stator coil by conformal felt three.
Preferably, the bottom of described deep bead forms inner circle, and this inner circle contacts with described stator coil end, and the uneven gap of height of contact portion is filled by conformal felt four circumference, and with sealing neutral silicone resin two, smears curing with door and window.
Preferably, between described wind blocking cylinder or described excessive plate and described stator coil, be provided with support, the top of fixed block and support are closing, and the bottom of fixed block compresses end hoop.
The utility model wind path packed configuration is by deep bead, wind blocking cylinder or excessively plate, conformal felt, polyester adhesive-bonded fabric, air guide ring are used in conjunction with a new air guide structure of formation, this structure has been banned traditional air damper structure, guaranteeing, on the respond well basis of motor ventilation, motor volume have been reduced to 20% left and right; When end hoop fixedly saves colligation end bander with fixed block, securing member and support; Thereby reduce motor manufacturing cost and operating cost.This new structure material-saving and consuming timely there is less certain economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is IP23 type motor partial sectional view;
Fig. 2 is IP44 type motor partial sectional view.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment 1
As shown in Figure 1, the electric motor winding end wind path packed configuration of applying on IP23 type motor comprises: deep bead 2, wind blocking cylinder 3-1, conformal felt, polyester adhesive-bonded fabric, stator coil 8, sealing neutral silicone resin, air guide ring 10 for door and window.
The every end of stator coil 8 end inner circle is laid an air guide ring 10, air guide ring 10 is smeared curing with stator coil 8 use door and windows with sealing neutral silicone resin one 9-1, depending on having larger gap between actual conditions air guide ring 10 and stator coil 8, with conformal felt three 6-3, fill gap.
8 hypotenuse gaps of adjacent two stator coil are folded into square filling with conformal felt one 6-2, with the object that reaches tensioner coil and keep out the wind, depending on actual conditions, if which floor or parcel epoxy phenol aldehyde glass cloth laminated board hypotenuse excesssive gap can fold more.Polyester adhesive-bonded fabric two 7-2 fillings for each stator coil 8 nose.
Gap between each stator coil 8 upper strata, end Bian Yu lower floor limit, at filling conformal felt one 6-2 place, fills with conformal felt two 6-1 circumference by inner side unshakable in one's determination, and fill with polyester adhesive-bonded fabric one 7-1 circumference in outside.
On support, weld wind blocking cylinder 3-1, the top of deep bead 2 and wind blocking cylinder 3-1 are closing, the bottom of deep bead 2 forms inner circle, should contact with stator coil 8 ends, contact portion coordinates conformal felt four 6-4 circumference to fill to solve the uneven gap of end winding height, with door and window, with sealing neutral silicone resin two 9-2, smears curing (this fluid sealant does not react through test and winding insulation paint).
Motor cooling air is pressed the wind path circulation that in figure, direction shown in arrow forms, and can reach desirable cooling effect.
By the filling of above-mentioned winding overhang wind path and keep out the wind, and ventilation hole on stator pressing ring and support, thus cooling winding overhang effectively.Meanwhile, the winding overhang wind path closed structure that the utility model provides, dwindles airspace and has increased blast, cooling air and outside motor air intake that rotor fan produces only can be circulated by the reserved space of design filling, thereby avoided leaking out and vortex phenomenon.
The utility model has also designed the fixing of end hoop 1, was all will hold hoop 1 together with 8 colligations of every stator coil with washing glass rope in the past, and along with end winding length is partially long, design two ends hoop, flow chart is quite loaded down with trivial details consuming time like this.For the utility model, fixed block 4 fitted bolts, nut, packing ring and support 5 are fixing, even circumferential distribution 6-8, be specially: fixed block 2 for top bolt, nut and packing ring put together on support 5, joint hole is designed to mounting hole, be convenient to end hoop 1 and be subject to stator coil 8 manufacturing variations, easily adjust installation site, the bottom of fixed block 2 compresses end hoop 1.
Embodiment 2.
The disclosed electric motor winding end wind path packed configuration of applying on IP44 type motor of the present embodiment is analogous to embodiment 1, difference is: the wind blocking cylinder 3-1 in Fig. 1, while being coordinated by support and cooler in Fig. 2 structure, the dull and stereotyped sealing of cooler design, adopt excessive plate 3-2, to guarantee that cooling air does not run off.
In embodiment 1 and 2, wind blocking cylinder 3-1 or excessively plate 3-2, air guide ring 10, conformal felt, the equal symmetric design of polyester adhesive-bonded fabric, be convenient to exchange and general.
