Description
The application be application No. is：2016101574905, invention and created name is：Using axis circulation wind realize stator closing with
Rotor opens the motor of draft type, the applying date is：The divisional application of application for a patent for invention on 03 17th, 2016.
Technical field
The present invention relates to commercial Application and driving rolling stock totally-enclosed self-ventilation motor.
Background technology
The stator of threephase asynchronous and rotor heating about respectively account for half, and the stator fever of industrial motor is omited than rotor
Height is used for the traction motor of rolling stock since live load is big, and rotor slip is big, and rotor heating amount can reach overall hair
More than half of heat；
Rolling stock travels on two one steel rails, 1435 millimeters of standard gauge, traction motor, shaft coupling, gear-box group
At power plant module be just placed in this fixed space, while also needing to retain certain daily maintenance to operating personnel and protect
Support space；Rail traffic simultaneously is operated in open-air atmosphere, is subjected to the test that various sleet, dust, dust storm corrode, so track is handed over
It is that small, light-weight, power density is high to be open to traffic to the general requirement of traction motor, and it is strong to resist adverse circumstances ability.
The ventilating and cooling mode of threephase asynchronous is generally divided into open self-ventilation, closed formula self-ventilation, opening
Formula forced ventilation：
1. for existing open self-ventilation motor：Cooled external air is directly through stator and rotor surface, band
Walk most of heat, good cooling results；The disadvantage is that fixed subcoil insulating system is easy to be invaded by extraneous dust, moisture, greasy dirt
Erosion, according to the statistics of international motor association, since stator insulation failure causes the probability of electric motor fails to account for overall three one-tenth
More than, electric motor fails caused by bearing fault are only second to, for open motor, the probability meeting of stator insulation failure occurs
Higher；
What currently metro industry was commonly used is open self-ventilation traction motor, according to the total of actual use situation
Knot, after motor puts into operation 10 years, stator insulation failure rate will rise rapidly, the traction motor moon event of single line
Barrier rate is likely to be breached 2~3, and occurs mainly in insulation fault；
It usually needs that dust removal by filtration device is installed in the air inlet of open self-ventilation traction motor, removes cooling air
In most of dust.Dust removal by filtration device needs regular dismounting to clean, and the period is about 3 months, expends a large amount of artificial.
2. for existing enclosed self-ventilated type motor, advantage be stator insulation have clean working environment thus it is exhausted
Edge reliability is high；Deficiency is that stator is in direct contact with shell, and heat conduction efficiency is high, is easier to radiate by shell, and rotor
It is enclosed in shell, heat is difficult to distribute, so to improve the power and efficiency of enclosed motor, rotor heat dissipation is ratio
Larger challenge, the motor of same power and efficiency, enclosed motor have the volume of bigger relative to open motor
And therefore weight, material cost can also rise；
Rapid proliferation, the traction electric machine of tramcar are easy contact to current low-floor tramcar close to road surface at home
Rainwater and dust, it is necessary to use closed traction motor；In order to increase the space of passenger and channel above bogie, need to lead
The volume for drawing motor is sufficiently small；In order to meet the ramp of bigger by performance and improve Brake energy recovery rate, it is desirable that traction electricity
The power of motivation is sufficiently large, these factors all propose huge challenge to current traction motor design work.
3. for existing open forced ventilation motor, advantage is small, and light-weight, power density is high；It is insufficient
It is to need independent wind turbine and air duct, it is additional to increase cost and space requirement；
Current high ferro motor-car and locomotive it is commonly used be open forced ventilation traction motor because vehicle is to motor
Power requirement is high, and existing open self-ventilation motor volume is too big, and the space of bogie can not accommodate；It is open to force
Traction motor of divulging information needs independent wind turbine and air duct, is arranged in compartment in the following, installment work is troublesome, be vehicle factor very
One work of headache.
4. the rotor heating of threephase asynchronous is more, usual working rotor temperature is higher by 50 to 100 than stator operating temperature
Degree, rotor heat are easy to be conducted to bearing by axis, and bearing operating temperatures height can reduce the performance of lubricating grease and then lower bearing
Service life；The heated excessively expansion of bearing inner race may make the working gap of bearing disappear, and bearing is stuck and then burns motor.
