Description
Technical field
The present invention relates to a kind of motor.
Background technology
Its structure of existing squirrel-cage motor is mainly as follows: the motor bed-plate inner peripheral surface that two ends are provided with end cap is provided with the stator being comprised of stator iron core for silicon steel sheet and stator winding, in stator, be provided with the rotor being formed by silicon steel sheet rotor core and cage modle winding, the rotor that these two ends are provided with rotor fan blade is fixed on motor shaft, one end that this motor shaft is positioned at motor bed-plate is provided with fan, and the other end stretches out electric motor end cap.At present, the type of cooling of squirrel-cage motor is divided into external refrigeration and the large class of internal cooling two.External refrigeration great majority adopt air cooling, for accelerating cooling effect, conventionally with fan, to motor, dry, and mobile air is contacted with iron core, stator, rotor winding end and the casing outer surface of motor, and the heat that is transmitted to these positions is taken away.Because motor is comprised of the different parts of many physical propertys, heat-transfer capability is different, the fast components interior heat that conducts heat is delivered to surface very soon, and the components interior heat that conducts heat slow is difficult to pass to surface, cause this part temperatures to raise, light affect the normal performance of this component capabilities, heavy affect useful life of whole motor.
Summary of the invention
The object of the invention is to provide a kind of internal heat transfer efficiency high, the heat pipe motor that heat-sinking capability is strong.The present invention improves the main pyrotoxin stator of motor, the heat-transfer capability of rotor by heat-pipe elements, reaches the cooling object of motor.
The present invention is provided with in existing motor stator-core entity part several round slot bores that opening is located at two ends, preferably the center line of these round slot bores is parallel with motor shaft and equal to the distance between center line of motor shaft, the internal diameter of this round slot bore is corresponding with heat pipe external diameter, a heat pipe is set in each round slot bore, its heat absorbing part is positioned at round slot bore, and the heat release of heat pipe is partly positioned at outside stator core.Above-mentioned heat pipe is established the vacuum tube of heat-transfer working medium in being, preferably the inside heat pipe on this stator is wick structure, to utilize capillarity passback liquid working substance.
Between rotor core entity part two ends and fan blade, be respectively equipped with opening and be located at several round slot bores on end face, the internal diameter of this round slot bore is corresponding with heat pipe external diameter, a heat pipe is set in each round slot bore, and heat pipe heat absorbing part is positioned at round slot bore, and heat release is partly positioned at outside rotor core.Above-mentioned heat pipe is established the vacuum tube of heat-transfer working medium in being.The center line of above-mentioned these round slot bores is parallel with motor shaft and equal to the distance between center line of motor shaft, or center line and the motor shaft of these round slot bores intersect certain angle, one end that heat pipe is positioned at rotor is than being positioned at one end outside rotor distance to motor shaft.Preferably this epitrochanterian inside heat pipe is wick structure.Above-mentioned heat pipe is fixed in rotor core by extruding or welding manner.
The course of work of the present invention is: when rotor, the heat that rotor core and rotor bar produce is absorbed by the working medium in rotor heat pipe, and working medium conducts to the fan blade surface of two ends of rotor rotation by heat and falls apart with the wind.The evaporation section that condensed working medium is got back to rotor heat pipe under the axial thrust load of centrifugal force promotes, again receive the heat that rotor core and sliver transmit, so move in circles, the heat that rotor inner core and sliver are produced can promptly conduct to the surface of two ends of rotor fan blade.During motor work, the copper loss of stator winding and the iron loss of stator core are the main origin of heat that produces stator temperature rise, the heat that these can be produced by loss with heat-pipe elements is promptly passed to the radiating end of stator both sides element from stator interior, by the cooling fan on motor reel, these heats are taken away again, the temperature rise of motor each several part is controlled within the specific limits.
The present invention compared with prior art tool has the following advantages:
1, the heat transfer efficiency that has improved motor stator, rotor, decreases the temperature rise of motor interior, is conducive to improve motor insulation property, improves the overload capacity of motor, extends motor useful life.
2,, due to the flexibility of heat-pipe elements shape, make embedding flexible, simple in structure in stator, rotor of element.
3, the temperature rise due to motor interior reduces, and also helps the efficiency that improves motor.
