Abstract
The utility model discloses a winding insulation and heat conducting structure for water cooled stator base motors. The both ends of the motor base are provided with motor end caps, and a circulating water channel is arranged in the thick wall of the motor base. The utility model is characterized in that epoxy resin compound insulators mixed by epoxy resin, glycerine and silicon micronized powder are poured and filled in the processed and pressed iron core of the stator and the both ends of the stator winding. The winding insulation and heat conducting structure for water cooled stator base motors can make a water cooled motor have better temperature reducing effect.
Description
Technical field
The utility model belongs to motor, relates to a kind of winding insulation and conductive structure of water cooling base motor.
Background technology
The height of electric machine temperature rise directly has influence on whole motor performance index and reliability, and therefore, concerning design of electrical motor person, one will consider how to make motor effectively to lower the temperature, and two will study how to control temperature rise.In the prior art, one of cooling measure of motor is that the motor stator support is carried out the water-cooled design, as shown in Figure 2, the lateral wall 4 of motor stator support is provided with the circulation water channel, take away the heat that motor gives out by cooled circulated medium, its heat transferred approach is: a part of heat in unshakable in one's determination 5 is directly passed to support 4, is taken out of from delivery port by water channel 3; The heat of stator winding 6 and end relatively disperses, and major part is undertaken distributing after the heat exchange for end cap 1 and 4 by transfer of air again.As everyone knows, the pyroconductivity of air is very low, and heat-conducting effect is relatively poor, because the caloric value of high power density motor inside is very high, particularly the coil windings caloric value is higher, depends merely on air heat conduction and is difficult to satisfy the cooling requirement, and the time has just been grown and may burn out winding.
Summary of the invention
The purpose of this utility model provides a kind of winding insulation and conductive structure of water-cooled stator support motor, to improve insulation and the heat conduction between stator winding end and the water-cooled stator inboard wall of base, improves the cooling effect of water-cooled machine, guarantees that motor reliably turns round.
The technical solution of the utility model that realizes above-mentioned purpose is, it is full of the composite epoxy resin mix insulation of epoxy resin, glycerol and silicon powder body to reach stator winding two ends pouring filling in the stator of processing, suppressing, so that tight exists between stator line bag and out frame.Said the utility model, the a part of heat of stator core inside is directly passed to support and is taken out of from the mouth of a river by water channel, and another heat partly in the heat of stator winding and end and the stator core is delivered to support after being concentrated by the epoxy insulation body and carries out being taken out of in the lump by water channel after the heat exchange.
The utility model has the advantages that, because the utility model stator core and word winding two ends all encapsulate with epoxy resin composition, no gap exists between itself and motor stator support, in the stator, the heat that sends of line bag particularly, can be delivered on the support that is connected with circulating cooling medium by the epoxy insulation body, carry out taking out of by water channel after the heat exchange.Because the pyroconductivity of epoxy medium is higher than the pyroconductivity of air, so the utility model makes water-cooled machine have better cooling-down effect.Model machine of the present utility model proves, adopt the motor of epoxy construction water-cooled stator support, the cooling rear motor temperature rise can drop to about 40K, and the motor of the water-cooled stator stand structure of epoxy construction of no use by air cooling after, the temperature rise of motor is probably about 70K.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of existing general water-cooled stator stand structure motor.
Embodiment
Embodiment of the present utility model as shown in drawings.Below in conjunction with accompanying drawing the utility model is specified.
Seen that by Fig. 1 number in the figure 8 is a rotor, 4 is electric machine stand, and support 4 two ends have electric motor end cap 1, are provided with the circulation water channel in the wall thickness of electric machine stand 4, and number in the figure 3,7 is the entery and delivery port of cool cycles current.Present embodiment reaches stator winding 6 in the stator core 5 of processing, suppressing two ends pouring filling is full of the composite epoxy resin mix insulation of epoxy resin, glycerol and silicon powder body 2.
