Circumferentially evenly distributed to have multiple gussets 7, each gusset 7 is set along the axial restraint of rotating shaft 1, is constituted between each two adjacent webs 7
Deep bead 5 is fixedly installed at axial ventilation road 9, the center cross-sectional in each axial ventilation road 9, the center line of deep bead 5 is to the left
Extension forms left flabellum 2, and the center line of deep bead 5 extends to form right wing leaf 8 to the right, the height of left flabellum 2, right wing leaf 8 and deep bead 5
No more than the height of gusset 7.In the present embodiment, deep bead 5 and the gusset 7 of the both sides of axial ventilation road 9 where deep bead 5
Weld together, and deep bead 5 is welded in rotating shaft 1, left and right fan is also welded in rotating shaft 1.
The rotor core 3 is provided with radial ducts 4, if rotor core 3 and left flabellum 2 and the corresponding area of right wing leaf 8
Domain is radial ducts compact district Y, and the radial ducts compact district Y left margins of rotor core 3 are using left region as left radial ventilation
Road puffs X, the radial ducts compact district Y right margins of rotor core 3 are left using right region as right radial ducts puffs Z
In radial ducts puffs X and right radial ducts puffs Z each two adjacent radial ventilating duct 4 the distance between,
More than in the Y of radial ducts compact district each two adjacent radial ventilating duct 4 the distance between.Radial direction i.e. in rotor core 3
Ventilating duct 4 presses the loose mode arranged distribution in middle intensive, both sides.
In motor operation, as rotating shaft 1 rotates, internal fan, radial ducts 4, the gusset 7 of rotating shaft 1 and flabellum 2 from
Blast is produced under mental power function, such wind path is formed：A part of wind is directly radially thrown away under internal fan effect, and it is fixed to flow through
Subcoil end, cools down stator coil；A part of wind is reached inside rotor core 1 by axial ventilation road 9, and then by radially
Ventilating duct 4 is flowed to outside rotor core 3, flows through rotor core 3, cooling rotor core 3, stator core, stator coil.Due to one
Part wind is thrown away under internal fan effect to radial direction, and a part of wind is when by axial ventilation 9 two ends of road from radial ventilation
Road 5 is discharged, and when reaching 3 middle part of rotor core, air quantity has been greatly reduced, and cooling capacity is poor.For in lifting rotor core 3
Between position air quantity, strengthen its cooling capacity, left and right radial ducts puffs and radial ducts compact district Y be set, at the same
The flabellum being of moderate size is set between the every two neighboring gusset in the middle part of rotating shaft 1, the pars intermedia of rotor core 3 had so both been added
The air quantity and draught area of position, enhance blast herein again, and the heat for accelerating radial ducts compact district Y is exchanged with the external world
Speed, prevent iron core middle part temperature high.
Compared to the radial ducts 4 being uniformly arranged in existing motor, wind by flowing from left and right radial ventilation layer by layer
When road puffs reach radial ducts compact district Y, the air quantity of reservation is more, with the flowing of wind, and the radial direction that can be taken away is led to
Air channel compact district Y heat is greatly increased.And radial ducts compact district Y area of dissipation and with the extraneous heat exchange that carries out
Path is increased, and also improves the speed that radial ducts compact district Y is exchanged with external heat.The rotor knot that the utility model is set
Structure substantially increases radial ducts compact district Y heat-sinking capability, so that the radiating efficiency of motor is strengthened, in actual production
In manufacture, it is possible to produce more powerful motor, high-power high voltage explosion separation motor is particularly suitable for.
The height of described deep bead 5 and height of the height no more than gusset 7 of left and right flabellum, it is ensured that rotor core 3
Can 1 normal rotation around the shaft.The moderate length of left and right fan, it is ensured that axial direction corresponding with left and right radial ducts puffs Z leads to
The air quantity in air channel 9, also ensures to enter finally into radial ducts compact district Y air quantity.With the rotation of flabellum, in internal rotor
Between section blast it is big, air enters the corresponding regions of the radial ducts compact district Y of axial ventilation road 9, when reaching axial ventilation road 9
Central cross-section at when, deep bead 5 forces air to the diffluence of radial ducts 4, rather than is axially flowed along rotating shaft 1, further
Strengthen heat dispersion.And because flabellum is very thin, even if being welded on the body surface of rotating shaft 1, also easily come off in high-speed rotation, keep off
Flabellum is fixed together by aerofoil 5 with gusset 7, can prevent flabellum from being come off in high-speed rotation.
Described radial ducts compact district Y radial ducts 4 is uniformly distributed, and left radial ducts puffs X is adjacent
Distance increases successively from right to left between two radial ducts 4, the right two neighboring radial ducts of radial ducts puffs Z
The distance between 4 increase successively from left to right.
It is preferred that, the left and right flabellum in rotor uses centrifugal flabellum, and the both sides of described rotor core 3, which are fixed, to be set
Centrifugal fan 6 is equipped with, centrifugal fan 6 is set in rotating shaft 1.The blast of centrifugal fan 6 is big, is more beneficial for improving the speed of heat exchange
Rate.
When motor is operated, the centrifugal fan 6 for being arranged at the both sides of rotor core 3 is rotated with the rotation of rotating shaft 1, increase
The blast at section F both ends is sensed with rotor core 3 corresponding rotor core, air enters axial ventilation road 9.In rotating shaft 1
The left flabellum 2 and right wing leaf 8 being fixedly installed between two gussets, rotate with the rotation of rotating shaft 1, add rotor core footpath
To ventilating duct compact district Y blast, the speed that the wind direction deep bead 5 in axial ventilation road 9 is moved is accelerated.Left radial ducts
Puffs X and right radial ducts puffs Z setting, reduce the wind flowed in axial ventilation road 9 and pass through left radial ventilation
The air quantity that radial ducts 4 in road puffs X and right radial ducts puffs Z is discharged, so that reaching radially logical
Air channel compact district Y air quantity is greatly increased.When wind arrival axial ventilation road 9 is middle, deep bead 5 forces wind to pass through radial ventilation
Radial ducts discharge in the Y of road compact district, while taking away amount of heat.The setting of left and right radial ducts puffs, significantly
The air quantity for reaching the intensive Y areas of radial ducts is increased, radial ducts compact district Y is provided with more radial ducts, increased
The path that big motor radiating area and heat are outwards distributed, enough air quantity, larger area of dissipation and more heats are handed over
Path is changed, coordinates deep bead 5 and left and right flabellum, greatly strengthen the heat-sinking capability of motor.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand；Embodiment of the present utility model can still be modified or to some technical characteristics progress equivalent substitution
The spirit of technical solutions of the utility model is not departed from, deep bead 5 is only set such as between per two neighboring gusset 7 or fan is only set
Leaf, prize-winning deep bead 5 replaces with other structures etc., and it all should cover the utility model and be claimed among technical scheme scope.
