Description
Technical field：
The utility model is related to technical field of motors, and in particular to the electric machine for fan with air-cooled configuration.
Background technology
The hertz number of alternating current is adjusted using frequency converter, can be achieved rotation at a high speed high-speed electric expreess locomotive it is existing it is more
Complete to research and develop and using, the general motor of the relatively same horsepower number of this kind of high-speed electric expreess locomotive, small in volume.
Turbo-dynamo rotates at a high speed compared to general motor under equal horsepower, but moment of torsion is small, so compared to general motor
Small volume.Therefore turbo-dynamo rotates at a high speed under small size, the frictional heat and stator produced with air, what rotor was produced
Many heat, but sufficiently cooling is the problem of needing to solve.
The heat that turbo-dynamo is produced such as will reduce the magnetic of fixed magnetite without supercooling, and more likely further reduction is solid
Stator coil electromagnetically, reduces motor performance or loss of performance.Although there is water-cooled turbo-dynamo to solve these problems
In production, but because the problem of equipment causes the big high energy consumption of volume in itself.Using the method for air cooling in the outside of motor coil
The another construction for setting cooling fan or cooling impeller being installed in one end of rotary body solves problem, but exists and manufacture complicated, energy consumption
Height, or increase rotary body weight reduction the problem of export.
Utility model content
The purpose of this utility model is to provide a kind of cooling air flow structure, improves the cooling effectiveness of turbo-dynamo.
Concrete technical scheme is：
There are motor lines in electric machine for fan with air-cooled configuration, including columnar outsides cover of electric machinery, outsides cover of electric machinery
Circle, rotor, stator；Described stator and rotor coaxial heart line are installed, and space is left between stator and rotor；Described rotor two
End passes through fore bearing and rear bearings respectively；Drive end bearing bracket and rear end are separately installed with the outside of described fore bearing and rear bearing
Have on lid, described rear end cap and be provided with the inside of air inflow aperture, described rear end cap on coil fixing port, coil fixing port
Guiding coil is installed, described guiding coil one end open towards air inflow aperture, one end open towards stator and rotor it
Between space, air enters described space and forms air film；Cooling dome, described cooling are also equipped with the outside of described stator
Air heat dissipation channel, described air heat dissipation channel and the axis parallel of stator are provided with cover, described air radiating is logical
Road, air heat dissipation channel towards one end of rear end cap be air outlet.
Motor tempering air flowing and heating position cooling order be：
By the air inflow aperture of back end cover for motor, leaked-in air passes sequentially through rear bearing, enters fixed from guiding coil
Space between son and rotor, forms air film, by the heat absorption of stator and rotor, by fore bearing, then passes through cooling
Air heat dissipation channel in cover, by the generation heat absorption on the outside of stator, final hot-air is discharged to motor from air outlet
It is outside.
The electric machine for fan with air-cooled configuration that the utility model is provided, turbine is rotated at a high speed the heat produced
Can, flowed the heat discharge turbo-dynamo of the heating positions such as stator, rotor, revolved by high-speed electric expreess locomotive using effective cooling air
The air inflow aperture opened on swivel rear end cap introduces extraneous air, and leaked-in air, which is transported between stator, rotor, forms air
Film, air film discharges the cooling air of forced circulation by being fixed on the cooling dome of outside, improves cooling effectiveness.
