Abstract
The utility model discloses an axle air cooling motor; when the motor is working, the axle of the motor drives a fan to rotate; cold air outside the motor enters into the motor from an air inlet; under the effect of the centrifugal pressure of air, hot air in the motor passes through the gap between the rotor and the stator of the motor and moves to the other end inside the motor ; as the end of the upper end cover of the motor is a closed structure, the hot air can only enter into the axle of the motor from an air circulation hole and then discharged out of the motor from the air outlet of the axle of the motor; the cold air ceaselessly enters into the motor and the hot air is ceaselessly exhausted outside, thus achieving air circulation to timely discharge heat inside the motor and generated during the running of a bearing out, effectively reducing the temperature raising inside the motor, keeping the motor always in an effective scope and achieving the goals of improving the efficiency, reducing the running cost and saving the resources.
Description
One: technical field
This novel a kind of motor with air cooling, particularly motor stator and internally air-cooled motor but of axle of relating to.
Two: background technology
The motor of the air cooling in the prior art, normally open a circulation of air hole at motor shaft, motor is in the process of work, radiator fan running by motor, air is flow through in the circulation of air hole of motor shaft, thereby the heat that bearing is produced during with motor rotation is taken away, reduce the temperature of bearing, prolong the useful life of bearing, because whole this mode can only be cooled off the temperature of motor shaft, and another main source of motor its heat in the process of operation produces for the motor stator winding coil and since in the prior art heat of stator all be by shell by media discharge such as air, the heat of motor internal is difficult to discharge like this, cause the motor internal temperature to raise, its efficient will descend after motor temperature raise, and the power consumption of motor will cause the waste of social resources along with increase.
Three: summary of the invention
This novel purpose is: design a kind of stator and axle for inner loop air cooling mode, and do not influence the motor that is connected with miscellaneous equipment, thereby temperature rise when reducing the motor operation raise the efficiency, the reduction operating cost economizes on resources.
The following structure of this novel employing realizes above-mentioned purpose, have air admission hole at motor bottom end cover (near radiator fan) end for circulation of air, in the axle of rotor, have the venthole of circulation of air equally, making motor shaft is hollow state from fan end to motor upper cover, has the circulation of air hole in motor on the motor shaft of upper end cover gap.
Adopt as above structure, other structure in the motor remains unchanged, during machine operation, motor shaft drives fan and rotates, the outer cold air of motor enters motor internal by air admission hole, because the centrifugal pressure effect of air, the hot-air that makes motor internal by the intermittence between rotor and the stator other end to motor internal move because the upper end cover end of motor is a closed type structure, hot-air can only enter in the motor shaft in the circulation of air hole, then the gas outlet by motor shaft with exhaust of hot air outside motor, circulation according to this, cold air constantly enters motor internal, and hot-air is constantly discharged, thereby the heat that produces when making motor internal and bearing owing to operation is discharged timely, effectively reduced the temperature rise of motor internal, made motor remain at scope efficiently, reached and raise the efficiency, reduce operating cost, aim of saving.
Four: description of drawings
Fig. 1 is this novel sectional structure chart
Fig. 2 is this novel part sectioned view
Five: embodiment
As depicted in figs. 1 and 2, this new structure comprises: motor stator 1, rotor 2, motor shaft 3, upper end cover 4 and bottom end cover 5, fan 6 etc., wind-guiding leaf 11 is installed on fan 6,5 places have air admission hole 7 at the motor bottom end cover, effect owing to wind-guiding leaf 11 when fan 6 rotates makes centrifugal air enter motor internal by air admission hole 7, owing between rotor 2 and the stator 1 space 8 is arranged, hot-air in the motor is because after being subjected to the extruding of cold air, upper end cover 4 places by space 8 flow direction motors, owing on motor shaft 3, have the hole of hollow up to upper end cover 4 places, simultaneously have opening 9 at upper end cover 4 places of motor shaft 3, hot-air flows by the space of opening 9 in motor shaft 3, owing to have exhaust outlet 10 at motor shaft 3 by fan 6 ends, hot-air is discharged the motor outside thus, cycle down motor internal temperature rise according to this, prolonged the useful life of axle, thereby made motor remain at scope efficiently, reached and raise the efficiency, reduce operating cost, aim of saving.
Claims (4)
1. ventilated machine, it is characterized in that: have air admission hole at motor bottom end cover place for circulation of air, in the axle of rotor, have the venthole of circulation of air equally, making armature spindle is hollow state from fan end to motor upper cover, has the circulation of air hole in motor on the motor shaft of upper end cover gap.
2. ventilated machine according to claim 1 is characterized in that: the air admission hole that the motor bottom end cover leaves can be one and also can be a plurality of.
