According to data compiled by the university of california, davis, united states, by the end of 2013, teslamodels, the third-highest market share (9. 97 per cent) of the global mainstream new energy electric motor vehicle model, was mostly a vehicle with a long-magnetic synchronous machine. The emp plays an important role in electric cars. As a result of the introduction of high-performance rare soil permagnetics, the permanent synchronous electrons function more stable, reliable, have longer useful life and have higher power density, smaller volumes and greater efficiency。
China has a clear advantage in the field of rare earth and has the largest reserves of rare earth in the world, and, after more than a decade of development, china has built up a very powerful group of rare earth field magnetizer producers, whose product categories cover all types of rare earth and permanent magnetic material required for the production of rare earth field magnetic machines。
According to professor shen, a member of the british institute of engineering and technology (iet), the world's leading engineering technology organization, “china has established a complete industrial chain and a perfect industrial ecosystem for rare earth-enhanced magnetic machines, which have a clear advantage over the cost of raw materials and production in the european and american countries, and are no less favourable in terms of technical indicators than developed countries.”
At present, china has developed and produced rare-earth magnetic and synchronous power units that are supplied to a number of well-known automobile companies, including the united states fisco electric vehicles and chinese brands such as cheshire, wantai, jili, huangtai, haimar and biadi. “the world is developing a green economy, including the promotion of new energy and electric cars. China's rare-earth yongjong magnetic electric machine is perfectly capable of meeting market demands.” professor shen said。
There is a very wide range of prospects for the application of rare-earth emps. It was explained that electric power consumes more than 60 per cent of the total grid power, so that the economic, environmental and social value of the efficient power plant is extremely high, and rare-earth magnetic power plants are one of the main technological means of efficient power. According to professor shen: “the rare earth empirical magnetic machine is the preferred of future high-end electric power-driven systems and can be widely applied in areas such as transport and transport, high-end processing equipment and robots, efficient wind and pumps, and white household electricity. China should continuously upgrade the performance of rare earth and electrotechnologies, continue to develop electrical design and drive control technologies, and meet the increased market demand for rare earth and turquoise machines.”
Professor shen jianxi is a member of iet and a professor and doctoral mentor at zhejiang university, faculty of electrical and electrical sciences. He specializes in research in the expansion structure of the emp, optimization design, driver control and application。
