Description
Technical field
The utility model relates to motor stator structure, is specifically related to the radiator structure of motor stator winding.
Background technology
Motor operationally can produce a large amount of heat, and motor stator winding also will produce " copper loss " in machine operation engineering, should " copper loss " all occur with the performance of the form of heat, if can not effectively the heat of motor internal be shed, the operating efficiency of motor will be affected, serious even motor damage.Existing electric machine stator iron is connected heat conduction with between winding by skeleton, and motor skeleton adopts nylon material (thickness 1-1.5mm) mostly, conductive coefficient is lower, and due to the rigidity of winding, stator core and winding two ends can be made to fit completely, can gap be had, thus the contact area of stator core and winding is reduced, then reduce the radiating efficiency of motor stator, hinder the heat transfer of motor internal, reduce the radiating efficiency of motor.
Utility model content
The motor skeleton thickness of existing nylon material is thicker and conductive coefficient is lower, cause the heat transfer efficiency between electric machine stator iron and winding lower, and there is certain rigidity due to stator winding, thus winding can not be fitted completely when wound core iron core, namely there will be space in stator core and winding two ends, so also can affect the heat-conducting effect of stator core, finally all can reduce the radiating effect of motor internal, affect the operating efficiency of motor.
For solving the problem, the utility model proposes a kind of new electric machine stator winding heat dissipation mechanism, skeleton between stator core and stator winding is set to polyimide insulative membrane structure, and silica gel heat conductive pad is set in stator core and gap, stator winding two ends, make stator core and stator winding close contact, contribute to the heat conduction efficiency that it is mutual.
For achieving the above object, the technical solution of the utility model is:
A kind of electric machine stator winding heat dissipation structure, comprise iron core, winding, skeleton, described skeleton is arranged between described iron core and described winding, and described iron core and gap, described winding two ends arrange heat conductive pad; Described heat conductive pad is silica gel heat conductive pad; Described skeleton is polyimide insulative film; Described iron core is silicon steel sheet; Described winding is copper coil.
Compare existing electric machine stator winding heat dissipation structure, the utility model has remarkable advantage and beneficial effect, is embodied as:
Use electric machine stator winding heat dissipation structure of the present utility model, skeleton between stator core and stator winding is set to polyimide insulative membrane structure, thickness reduces greatly, and silica gel heat conductive pad is set in stator core and gap, stator winding two ends, make stator core and stator winding close contact, improve the heat conduction efficiency of motor internal.
Accompanying drawing explanation
Fig. 1 is the utility model electric machine stator winding heat dissipation structural representation.
Embodiment
Specific implementation method of the present utility model is as follows:
The motor skeleton thickness of existing nylon material is thicker and conductive coefficient is lower, cause the heat transfer efficiency between electric machine stator iron and winding lower, and there is certain rigidity due to stator winding, thus winding can not be fitted completely when wound core iron core, namely there will be space in stator core and winding two ends, so also can affect the heat-conducting effect of stator core, finally all can reduce the radiating effect of motor internal, affect the operating efficiency of motor.
For solving the problem, the utility model proposes a kind of new electric machine stator winding heat dissipation mechanism, skeleton between stator core and stator winding is set to polyimide insulative membrane structure, and silica gel heat conductive pad is set in stator core and gap, stator winding two ends, make stator core and stator winding close contact, improve the heat conduction efficiency of motor internal.
Embodiment of the present utility model is illustrated below in conjunction with accompanying drawing:
Be illustrated in figure 1 the utility model electric machine stator winding heat dissipation structural representation, wherein 1 for stator core, 2 be stator winding, 3 for motor skeleton, 4 be heat conductive pad.
Described stator winding 2 is wound in described stator core 1, and described motor skeleton 3 is arranged and between described stator core 1 and described stator winding 2, described heat conductive pad 4 is arranged at the gap at described stator core 1 and described stator winding 2 two ends.
Described stator core 1 is silicon steel structure, and described stator winding 2 is copper coil structure, and described motor skeleton 3 is that polyimide insulative film equal thickness is less and the structure that conductive coefficient is high, and described heat conductive pad 4 is the material of the good heat conduction effect such as silica gel.
Existing motor skeleton is generally nylon material, and the thickness of nylon material is generally at 1-1.5mm, namely the thickness between electric machine stator iron and stator winding is 1-1.5mm, and the conductive coefficient of nylon material is lower, reduce the conduction of motor internal heat, in the utility model embodiment, nylon material is replaced with polyimide insulative film, the thickness only 0.05mm of described polyimide insulative film, for 1/30 ~ 1/20 of nylon material, thickness greatly reduces, namely the distance between described stator core and described stator winding is reduced, be conducive to the conduction of heat, and the conductive coefficient of described polyimide insulative film is large compared with nylon material, further increase the efficiency of heat conduction.
The metal materials such as copper cash are generally due to stator winding, and the winding of these materials be wound around stator core process in due to its intrinsic rigidity characteristic, described stator winding and described stator core can be caused to fit completely, particularly at complications place, so motor heat-conducting effect also can be caused poor, thus in embodiment of the present utility model, silica gel heat conductive pad is set in described stator core and described stator winding two ends place, described silica gel heat conductive pad be wound around stator winding time due to crimp can automatic filling to the space between described stator core and stator winding, conductive coefficient due to described silica gel heat conductive pad is greater than the conductive coefficient of air, therefore, being provided with of this heat conductive pad helps improve the heat-conducting effect between stator core and stator winding, finally can improve the heat transfer efficiency of motor internal, improve the operating efficiency of motor, also can ensure the operational environment of motor simultaneously, extend the useful life of motor.
For being one exemplary embodiment of the present utility model; should be understood to be claims of the present utility model protection range in a certain demonstrative example wherein; there is directiveness effect those skilled in the art being realized to corresponding technical scheme, but not to restriction of the present utility model.
