the permanent magnet synchronous motor and drive system for power used in pure electric and hybrid electric vehicles have reached the stage of market application. With the introduction of the national plan for the adjustment and revitalization of the automotive industry in 2009, and the State Council's ten pull calibration: press the "pull" button, and the plan to "pull" the lights on the city to thousands of vehicles in 20 cities has been expanded. According to the discussion draft of the national 12th Five year development plan, by 2010, 2015 In 2020, the scale of ten thousand, one million and ten million new energy vehicles will be formed respectively, which will raise the development strategy of new energy vehicles and related industries to the national strategy, bring opportunities for the development of new energy vehicle industry and key parts industry, and bring broad market space for environmental protection and energy-saving vehicle power motors and drive system products

the extensive use of electric drive systems in automotive systems has brought benefits to motor manufacturers. According to a latest report from imsresearch, the shipment of permanent magnet brushless DC motors used in the automotive industry will exceed that of DC servo motors and stepper motors from 2012 to 2017. The shipment of permanent magnet brushless DC motors will increase by 52%, and the sales will exceed 462million

motor parts technology may become a hot spot in the industry

due to the shortage of energy and the increasing environmental pollution, electric vehicles show strong vitality and are generally favored by automobile manufacturers and consumers. Data shows that by 2010, electric vehicles will account for a quarter of the global demand for vehicles, with a total of 20million vehicles. A total of 5415 meters of DN500 welded pipe will be installed in the project. General motors of the United States, Toyota of Japan, Citroen of France and other large automobile companies all take electric vehicles as the development direction

China also attaches great importance to this. Electric vehicles have been listed by the Ministry of science and technology as a key project for the transformation and upgrading of China's household appliance industry during the Tenth Five Year Plan period, and it is also one of the important contents of developing green transportation in the eleventh five year plan. Therefore, the motor industry has great market potential

for the current motor development, the technical upgrading of key parts is extremely important to improve its reliability and service life. At the China automotive motor technology and Application Forum, the China Automotive Consulting Center invited experts from relevant enterprises such as Dayang electric New Power Technology Co., Ltd., Delphi Parker Electric System Co., Ltd., Schaeffler Group, etc. to introduce and discuss the key components and new technologies of materials in the motor, and shared a series of solutions to improve the performance of key components

permanent magnetization is the future development direction of the motor

in terms of the motor drive technology of electric vehicles, due to the constraints of vehicle space and use environment, the motor drive system for electric vehicles is different from the ordinary electric drive system. It requires higher performance, higher volume/weight density and higher ambient temperature. The power electronics and motor technology used for ordinary motor drive can no longer meet its requirements. Therefore, permanent magnetization will become one of the development directions of automotive motors in the future

permanent magnet motor has the advantages of high efficiency, large specific power, high power factor, high reliability and easy maintenance. Using vector control, the variable frequency speed regulation system with light weight and floating on the water can make the permanent magnet motor have a wide speed regulation range. Therefore, permanent magnetization of motor has become one of the important development directions of motor drive technology
