Modern power grids are no longer to AC UHV power grid development, but also because there UHVAC itself following several fatal flaws: ① large environmental costs. Due to the construction of UHV AC is on top of existing 500 kV grid and then superimposed a 1000-volt power, rose to the power grid by the end of the post, should be down to 500 to 220 kV redistribution kilovolt power ye3, so it not only can not replace 500 kV substation capacity and the corresponding 500-kilovolt transmission line, will make our grid voltage level to six layers from the existing five-layer (ie, becomes 0.4 / 10/110/220/500/1000 kV) ye3 electrical plant, to become the world's largest power grid voltage level. And UHV AC noise, electromagnetic pollution on the environment than the ultrahigh strength ye3 motor manufacturers, it is a monster power transmission equipment, the need is greater area (with tower double UHV AC line tower about 80 meters, a width of about 70 meters a corridor UHV AC substations covering 9-20 hectares). ② poor investment returns. UHVAC from technical point of view, long-distance transmission is better UHV DC, close to 500 kV voltage transmission is better, but the investment is great, is a "cost" of the program is low. China Southern Power Grid of UHV AC and DC schemes plus AC 500 kV UHV grid schemes are compared, the results of the former than the latter investment 600-1000 billion, height of about 1.3-1.5 times [5]. ③ two booster motors ye3 government subsidies, both to increase energy loss, but also reduce the transmission capacity. UHV AC transmission, power generally required to be aggregated to 500 kV step-up substation, then boost to AC UHV power grid. 3D printing motor upcoming Recently, the US company United Technologies Research Center (UTRC) Researchers with the US Department of Energy's ARPA-E (AdvancedResearchProjectAgency-Energy) project signed a contract, the purpose is to develop a non-use of rare earth magnets induction motors, such motors can be used on electric vehicles. However, they are not independent to complete this complex project, but, Pennsylvania State University and working with the Connecticut WaydeSchmidt increasing material manufacturing center. UTRC project leader explained their research methods: "Our original idea was to develop a 3D can print out the copper conductor, insulated steel components and machines, as these parts print complete, a motor will appeared, but currently we use both kinds of materials from a machine manufactured in huge technological gap there, so we will break down the problem, and then concentrate on each break. "induction motor due to the developer decided to use 3D printing to produce engines then conventional engine technology architecture has clearly not appropriate, so they decided to redesign the engine but also to make it more suitable for increasing material manufacturing (ie, 3D printing) technology. Then set up a special team to complete the task of redesigning the electric motor responsible JagadeeshTangudu.Tangudu describes the development of a new engine design ideas: "The main purpose of this project is to design a special engine, this engine is assuming increasing Under the conditions of material manufacturing technology to maximize energy efficiency. We do not have to limit the engine design, so it looks like the end may be quite non-traditional or even very weird. Obviously, we will face many technical problems.
