Speed reducer is easier to damage.
In recent years, it in power industry Air-Cooling Island, is got over using permanent-magnet synchronous direct drive motor+frequency converter driving structure form
Come more extensive, which has many advantages, such as that overall efficiency is high, maintenance is low, overload starting ability is big, but due to environment temperature
Degree is high, and load is big, and permanent-magnet synchronous direct drive motor is simple air-cooled only with natural heat dissipation or outside, does not do special designing, electricity
Machine coil also can excess temperature quickly, cause motor to burn, cause user's property loss.
Utility model content
In view of the deficienciess of the prior art, the utility model provides one kind for power industry Air-Cooling Island permanent magnet synchronous direct
Drive the cooling structure of motor.
To achieve the above object, the technical scheme adopted by the utility model is that: one kind be used for power industry Air-Cooling Island permanent magnetism
The cooling structure of synchronizing direct-drive motor, including permanent-magnet synchronous direct drive motor, the driving of the permanent-magnet synchronous direct drive motor
Shaft uses hollow shaft, and is successively arranged radiating rib plate and wind scooper in the outer surface of permanent-magnet synchronous direct drive motor, in permanent magnetism
The tail portion of synchronizing direct-drive motor is equipped with cooling blower；The cooling blower, radiating rib plate and wind scooper constitute outer cooling
System, the cooling blower and hollow shaft constitute internal cooling system.
Further, the cooling blower is axial flow blower or centrifugal blower.
Further, the hollow shaft and cooling blower are set gradually along shaft extension end of motor to electronic drive end unit.
Further, the outer cooling system, which sucks cold wind from motor-shaft extending end, flows through radiating rib plate along wind scooper, with
Heat exchange is carried out inside motor, after taking away heat, is become hot wind, is axially or radially discharged from cooling blower.
Further, cold wind is sucked from motor-shaft extending end and flows to motor tail end along hollow shaft by the internal cooling system,
Heat exchange is carried out with motor interior in hollow shaft, after taking away heat, becomes hot wind, is axially or radially arranged from cooling blower
Out.
The beneficial effects of the utility model are: the heat that the loss of electric machine generates passes using the technical solution of the utility model
It is delivered to inside radiating rib plate and hollow shaft, the negative pressure that cooling blower rotation generates, passes through cold wind hollow to wind scooper and motor
Axis is continually flowed into from motor-shaft extending end, and the outflow of cooling blower air outlet takes away the heat of loss of electric machine generation, to reach
To the purpose to the cooling heat dissipation of motor.
The wind scooper of cooling system and the void effect of motor-hollow axle, the characteristic that hot-air rises, cold air declines, add
The speed flowing velocity of cold air, increases motor cooling and cooling effect.
The utility model is designed by reasonable radiating rib plate, and the calculating of outlet and inlet open area, stringent fluid analysis are closed
The cooling blower power selection of reason improves motor radiating bottleneck, improves motor radiating performance, so that motor temperature declines 30 DEG C
Left and right guarantees permasyn morot under the operating condition of power industry Air-Cooling Island harshness, and safe and reliable operation reduces maintenance
Cost improves production efficiency.
