Abstract
This patent provides one kind and can carry out directly cooling down to the conducting wire in iron core, and the electric machine iron core of good cooling results can significantly improve the power of motor using the electric machine iron core.The electric machine iron core is provided with hollow insulating seal in the wire casing of iron core, is the inlet and outlet of coolant liquid respectively at the both ends of insulating seal so that conducting wire is passed through from the boring of insulating seal.
Description
Technical field
This patent is related to electric machine iron core, such as stator core, rotor core, the especially iron core convenient for heat dissipation.
Background technique
The heat dissipation of machine winding is the maximum bottleneck for restricting power of motor and playing, and leads to the material practical efficiency of motor not
More than 50%, in order to improve the heat-sinking capability of motor, oil immersed type oil-cooled motor becomes developing direction, still, due to cooling oil with
Friction rotor will lead to biggish power loss, so, oil immersed type oil-cooled motor is not used largely so far, but backward is adopted
With oil whip cooling or end oil immersed type or spraying cooling.Although these types of cooling are changed than non-oil-cooled motor cooling effect
It is kind, but all cannot directly cool down stator interior conducting wire.This is because stator core is formed together by multi-disc silicon steel sheet stack,
It can not be sealed between silicon steel sheet, so stator interior cannot lead to oil.
Summary of the invention
The purpose of this patent is to provide one kind can carry out directly cooling, the motor of good cooling results to the conducting wire in iron core
Iron core can significantly improve the power of motor using the electric machine iron core.
Electric machine iron core described in this patent is provided with hollow insulating seal in the wire casing of iron core, so that conducting wire is from exhausted
The boring of edge seal passes through, and is the inlet and outlet of coolant liquid respectively at the both ends of insulating seal；In insulated enclosure body
There is the conducting wire fixing groove of the radial arrangement along iron core, conducting wire is passed through from conducting wire fixing groove on wall.
To further simplify the structure, the cooling liquid inlet of each insulating seal is in iron core one end, and whole or part
It is connected, forms the coolant liquid general import of iron core one end；The cooling liquid outlet of each insulating seal is and complete in the iron core other end
Portion or part are connected, and form the coolant liquid general export of the iron core other end.
This patent the utility model has the advantages that since insulating seal passes through winding slot of core, conducting wire passes through out of insulated enclosure body, institute
To be flowed into inside insulating seal from the import of coolant liquid, and can be direct from the coolant liquid that the other end of insulating seal flows out
It is cooling to conducting wire, to realize that the oil of core interior conducting wire is cold, the cooling capacity of motor is greatly improved, to improve the function of motor
Rate.The both ends of insulating seal are the inlet and outlet of coolant liquid respectively, and therefore, coolant liquid will not enter the soft magnetic materials for forming iron core
Between piece such as silicon steel sheet.Moreover, improving the intensity of iron core after insulating seal fills the wire casing in iron core, reducing slot
The vibration of mouth is to reduce the noise of motor.
Detailed description of the invention
Fig. 1 is the cross-sectional view of motor stator core；
Fig. 2 is the main view of motor stator core；
Fig. 3 is the side view of Fig. 2；
Fig. 4 is the partial enlarged view in Fig. 1；
Fig. 5 is the partial enlarged view in Fig. 2.
In figure, insulating seal 1, coolant liquid general import 11, coolant liquid general export 12, conducting wire fixing groove 13, stator core
2。
Specific embodiment
Referring to motor stator core shown in Fig. 1-3, in the wire casing for the stator core 2 being formed by stacking by soft magnetic sheet
It is provided with hollow insulating seal 1, one end parallel connection of each hollow insulating seal forms the coolant liquid around stator core one end
General import 11, other end parallel connection form the coolant liquid general export 12 around the stator core other end.On insulating seal inner wall
Conducting wire fixing groove 13 with the radial arrangement along stator core, conducting wire (not shown) are passed through from conducting wire fixing groove.
Coolant liquid can be cooling oil.
Direct oil in order to realize stator interior conducting wire is cold, and a closed insulated enclosure is arranged in the wire casing of stator
Body, insulating seal inside are hollow structure, and equipped with the conducting wire fixing groove for accommodating and fixing conducting wire, insulating seal both ends are whole
Or part is affixed to one another and is respectively formed coolant liquid inlet and outlet and passes to coolant liquid, can thus make real inside stator core
It now seals, to realize that the oil of stator interior conducting wire is cold, the cooling capacity of motor is greatly improved, to improve the power of motor.
Meanwhile after insulating seal fills the notch of iron core internal diameter, improves the intensity of stator, reduces the vibration of notch to reduce
The noise of motor.
Certainly, which can be used for production motor rotor core.
