Technical field
The invention belongs to technical field of motor manufacture, and in particular to a kind of radiator structure of stator winding and its making side
Method.
Background technology
The average temperature rising of stator winding in operation is no more than temperature as defined in the motor class of insulation, due to determining for motor
Sub- winding generally use organic insulation, its heat resistance and service life are far below wire and iron core, are the weak rings of motor
Section.At present, the electromagnetic wire in motor stator coil groove is typically in the state of bulk storage, and electromagnetic wire interlaced arrangement is in line embedding groove so that
Relative closure can not radiate in time in vallecular cavity, cause local temperature rise in motor too high, insulating materials aging is fast, service life significantly
Shorten.

Use the life-span.
To realize object above, the technical solution adopted by the present invention is：
A kind of radiator structure of stator winding, including housing and motor shaft, it is coaxially arranged in housing to have stator and rotor, institute
To state and stator winding is arranged with the line embedding groove of stator, the stator winding in line embedding groove is integrated by insulated paint is closely cementing,
Make to form the first air vent axially through stator between stator winding and line embedding groove inwall, on the motor shaft in housing
It is additionally provided with fan.
A kind of method for being used to make the radiator structure of stator winding, after described stator winding installation, use
Pore-forming rod passes through line embedding groove, after dipping lacquer, drying, pulls out pore-forming rod into the first air vent.
Prior art is compared, and the present invention has following technique effect：Process operation is simple and convenient, and radiator structure is reasonable.Fill
Divide the vallecular cavity arrangement thermal dissipating path using line embedding groove, and axial ventilation is formed in motor internal to ensure motor internal using fan
Temperature rise everywhere is uniform, so as to effectively avoid motor damage caused by local temperature rise is too high in motor, greatly promotes the resistance to of motor
Long property.
Brief description of the drawings
The content expressed by each accompanying drawing of this specification and the mark in figure are briefly described below：
Fig. 1 is the schematic diagram of the present invention；
Fig. 2 is the enlarged diagram in A portions in Fig. 1.
In figure：1. housing, 2. motor shafts, 3. stators, 31. line embedding grooves, 32. stator winding, 33. first air vents, 4. turns
Son, 41. second air vents, 5. fans, 6. pore-forming rods.
Embodiment
Below in conjunction with the accompanying drawings, by the description to embodiment, the embodiment of the present invention is made further specifically
It is bright.
A kind of radiator structure of stator winding, including housing 1 and motor shaft 2, it is coaxially arranged in housing 1 to have stator 3 and turn
Son 4, stator winding 32 is arranged with the line embedding groove 31 of the stator 3, the stator winding 32 in line embedding groove 31 is by insulated paint
Close cementing the first air vent for being integrated, making to be formed axially through stator 3 between stator winding 32 and the inwall of line embedding groove 31
33, it is additionally provided with fan 5 on the motor shaft 2 in housing 1.To ensure the winding of stator winding 32 installation, the groove of line embedding groove 31
Chamber area of section is typically larger than the area of section of stator winding 32, and it is one that the stator winding 32 in line embedding groove 31 is closely cementing
After body, while the compactness of the inner stator winding 32 of line embedding groove 31 is lifted, the vallecular cavity for also causing line embedding groove 31 vacant is passed through
The both ends of logical stator 3, to form the first air vent 33 that supply stream passes through, so as to the thermal diffusivity of upgrading slot inner stator winding 32
Energy.When in use, the work of fan 5 will cause motor internal to form axial ventilation, and gas can be pointed to by the first air vent 33
Stator winding 32 in line embedding groove 31 carries out cooling radiating, so as to ensure that motor internal temperature rise everywhere is balanced, avoid stator around
It is lost caused by group local temperature rise is too high.
Preferably, described rotor 4 is provided with the second air vent 41 through rotor core, first and second air vent 33,41
Parallel arrangement.So fan 5 just can radiate to stator 3 and rotor 4 simultaneously, also enable motor internal to form airflow circulating
Loop, it is further ensured that the uniformity of temperature rise everywhere in motor.
A kind of method for being used to make the radiator structure of stator winding, after the described installation of stator winding 32, is adopted
Line embedding groove 31 is passed through with pore-forming rod 6, after dipping lacquer, drying, pore-forming rod 6 is pulled out and forms the first air vent 33.So pore-forming rod 6 will
Extruding stator winding 32 makes it infiltrate insulated paint in the case of close arrangement and keeps the posture to be dried.Pulled out after drying
Pore-forming rod 6, due to the gluing effect of insulated paint, stator winding 32 will maintain the posture of close arrangement so that be obtained at former pore-forming rod 6
To form the first air vent 33.It is simple and convenient, it is easy to process.
Preferably, the area of section of the pore-forming rod 6 is less than the 30% of line embedding groove vallecular cavity area of section.Pore-forming rod 6 is cut
Face area is the area of section of the first air vent 33.For ease of the winding of stator winding 32, the area of section of stator winding 32
Usually the 70% of the vallecular cavity area of section of line embedding groove 31, so both can guarantee that the reliable installation of stator winding 32, and and can is abundant
The first air vent 33 is arranged using the vallecular cavity chamber of line embedding groove 31, lifts the radiating effect of stator winding 32.
Preferably, described pore-forming rod 6 is teflon rod.Polytetrafluoroethylene (PTFE) is resistant to the corrosion and its baking of insulated paint
Dry temperature, and its surface energy is low, with insulated paint friction lacquer painting will not be caused to grind when being extracted out of line embedding groove 31 as pore-forming rod 6
Damage or come off.
