Abstract
This invention relates to one process to sealing stuff between motor stator coil set end and shell, which is characterized by the following: with materials proportion as silicon rubber for 90 to 95 percent, adhesion for 3 to 5 percent, fix agent for 1 to 3 percent; then adding 300 pieces of quartz sand for condense plasma covering between coil set end and shell for naturally fixing; then through dissipation rip to cool outside to lower the motor temperature.
Description
Technical field
The present invention relates to seal inserts between a kind of motor stator winding end and the casing, belong to design of electrical motor, manufacturing technology field.
Background technology
The alternating current motor winding overhang does not contact miscellaneous part, fully among air surrounds, therefore the heat of end is difficult for distributing, especially two-pole machine, because its end is longer, the caloric value of end is bigger, to making the end hotter, thereby the temperature of the temperature rise of motor windings and bearing is improved, the temperature rise of alternating current motor or supporting bearing temperature are exceeded standard and defective.Therefore, need the good encapsulating material of insulation property and heat conductivility.
Summary of the invention
The object of the present invention is to provide between a kind of motor stator winding end and the casing and seal inserts, this inserts can reduce winding temperature rise and bearing temperature, thereby improves electric efficiency and increase the service life.
For reaching above-mentioned order, technical scheme of the present invention is: sealing inserts is a kind of insulation property and the good material of heat conductivility, its composition comprises silicon rubber, adhesive, curing agent, after being in harmonious proportion according to a certain percentage, add the thicker starchiness of quartz sand furnishing, be encapsulated between winding overhang and casing, spontaneous curing.
Beneficial effect of the present invention: the heat of motor end is passed on the casing by inserts, cool off in the coolant around by radiating ribs again, thereby reduce electric machine temperature rise.By practical application, can reduce electric machine temperature rise 5～10K.
Below in conjunction with drawings and Examples to the present invention's detailed description of making comparisons.
Description of drawings
Fig. 1 is material mixture ratio of the present invention and makes FB(flow block).
Embodiment
With reference to Fig. 1, the 1st embodiment, material mixture ratio is: silicon rubber contains 90%～95%, gluingly contain 3%～5%, curing agent contains 1%～3%.
Press the above-mentioned material proportioning and mix, add the above thicker starchiness of quartz sand furnishing of 300 orders then, be encapsulated between winding overhang and casing, spontaneous curing.
With reference to Fig. 1, the 2nd embodiment, the optimization material mixture ratio is: silicon rubber contains 93%, gluingly contain 4%, curing agent contains 3%.Press the above-mentioned material proportioning and mix, add the above thicker starchiness of quartz sand furnishing of 300 orders then, be encapsulated between winding overhang and casing, spontaneous curing.
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 fall into claim of the present invention.
