Description
Technical field：The present invention relates to a kind of Helium fan motor.
Background technology：At present, existing Large-power High-Speed motor is mostly horizontal unit, vertical unit cannot realize high-power and high speed, either vertical or horizontal type high-power unit cannot realize the service requirement of 800-4200r/min, and motor uses grease lubrication, and pollution is brought to surrounding environment, motor cannot be realized being worked under 65 DEG C of -243 DEG C of temperature difference, common electric machine is to work under 0.1MPa, it is impossible to worked under 7MPa, it is impossible to meet and work in HTGR primary Ioops 7MPa helium nonpollution environments.
The content of the invention：It is an object of the invention to overcome disadvantages mentioned above, a kind of Helium fan motor is provided, it mainly solves existing Large-power High-Speed motor and is mostly horizontal unit, vertical unit cannot realize high-power and high speed, either vertical or horizontal type high-power unit cannot realize the service requirement of 800-4200r/min, motor uses grease lubrication, pollution is brought to surrounding environment, motor cannot be realized being worked under 65 DEG C of -243 DEG C of temperature difference, common electric machine be 0.1MPa under work, cannot be worked under 7MPa, the problems such as work in HTGR primary Ioops 7MPa helium nonpollution environments can not being met.The object of the present invention is achieved like this, Helium fan motor by：Cooling blower, upper electromagnetic bearing, upper end cover, support, stator core, rotor, bottom end cover, lower electromagnetic bearing are constituted.Stator core is arranged in support, upper end cover is fixed on support with bottom end cover, upper electromagnetic bearing is fixed on upper end cover, lower electromagnetic bearing is fixed on bottom end cover, rotor upper end is fixed together by upper electromagnetic bearing, lower end is fixed together by lower electromagnetic bearing, and the upper end of rotor is equipped with cooling blower.The product Helium fan motor is high-power vertical high-speed induction motor, and in the helium pressure chamber of HTGR primary Ioops 7MPa, motor upper end environment temperature is 65 DEG C to whole machine installation, and motor lower end environment temperature is 243 DEG C, and power of motor is 4500 gigabits（KW）,Range of revolution is 800-4200r/min,Rotor axial load is 8500kg,Motor is oil-free grease lubrication,To surrounding environment without any pollution,Resistance to irradiation,Antidetonation,Disclosure satisfy that heavy duty,Revolution high and the requirement of adjustment,Performance safety reliability,Long service life,Extend maintenance cycle,The project is developed by the numerous scientific workers' hard-working of 6 years of company,The vertical machine of this power scale and revolution at home and abroad can be used for reference without ripe product,Realize electromagnetic bearing first set application in nuclear reactor,HTGR Nuclear Power Plant demonstration project has been put into China's 11th Five-Year National Program for Medium-to Long-term Scientific and Technological Development,Helium fan motor is the unique active main equipment of HTGR primary Ioops,The fund that costliness has been saved for China is developed and developed to this purpose.
Brief description of the drawings：
Accompanying drawing 1 is the structural representation of Helium fan motor of the present invention.
Electromagnetic bearing under electromagnetic bearing 3- upper end covers 4- supports 5- stator core 6- rotor 7- bottom end covers 8- on 1-cooling blower 2-
Specific embodiment：The most preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings, Helium fan motor by：Cooling blower 1, upper electromagnetic bearing 2, upper end cover 3, support 4, stator core 5, rotor 6, bottom end cover 7, lower electromagnetic bearing 8 are constituted.Stator core 5 is arranged in support 4, upper end cover 3 is fixed on support 4 with bottom end cover 7, upper electromagnetic bearing 2 is fixed on upper end cover 3, lower electromagnetic bearing 8 is fixed on bottom end cover 7, the upper end of rotor 6 is fixed together by upper electromagnetic bearing 2, lower end is fixed together by lower electromagnetic bearing 8, and the upper end of rotor 6 is equipped with cooling blower 1.
During work, it is aerial that rotor 6 floats over the rotation of rotor 6 by the effect of upper electromagnetic bearing 2 and lower electromagnetic bearing 8, and without any friction loss, rotating speed is up to 800-4200r/min.There is no any pollution to whole environment, electronics rotor 6 can realize that whole rotor is completely monitored when working, when rotor 6 works, cooling blower 1 produces cooling wind, the upper and lower electromagnetic bearing of motor is cooled down, intercept the high temperature of 243 DEG C of motor lower end simultaneously and transmit heat to motor, the support of motor about 4 end cap using the working condition requirement for strengthening being designed to meet the operation of Helium fan motor（Electric machine stand is separately applied for a patent）.
