annual Huazhang at the peak of technology

the national technological invention award is the country's contribution to the difficulty of original innovation, the level of independent innovation, and the promotion of scientific and technological progress The award with the highest comprehensive requirements for producing economic and social benefits represents the latest achievements of domestic technology application

this time, New Ocean Electromechanical Co., Ltd. won the second prize of the National Technological Invention Award jointly with Southeast University and Jiangsu University, which shows that new Ocean Electromechanical Co., Ltd. has been in the forefront of the industry in the field of motor production, learning and research, which has greatly promoted the development of China's motor industry

the only industry leader in the development of brushless motor

as we all know, motor, electronic control and battery are called "three electricity", which is the core technology of electric vehicles. The motor system is the part of energy and power, transportation, and the upper part, that is, the upper space. This experimental machine is mainly used to detect the maximum force of steel strands, the specified non proportional extension force, the maximum total elongation and the stress relaxation performance experiment, which are the key and core of heavy equipment in high-end manufacturing and national defense and military industry. Permanent magnet brushless motor has been widely used because of its high efficiency and energy saving. However, due to the inherent factors such as weak structural strength, high temperature loss of excitation risk, and the inability to directly regulate the magnetic field, the traditional permanent magnet brushless motor has a series of problems, such as difficult to further improve the motor power density, poor fault tolerance performance, narrow speed regulation range and so on. How to significantly improve the power density, fault tolerance and speed range of permanent magnet motor is the difficulty and key in the field of motor research

it is understood that the "key technology and application of strong fault tolerance and wide speed regulation permanent magnet motor" project is the only award-winning project in the national science and technology honor Hall of China's new energy vehicle industry, representing the breakthroughs and achievements of the new energy vehicle industry in promoting technological innovation and realizing the dream of becoming a powerful automobile country in recent years. With the support of more than 10 national projects such as the key projects of the National Natural Science Foundation of China and more than 40 provincial, ministerial and enterprise key research projects, he invented the "unilateral magnetic field" stator permanent magnet brushless motor and its implementation technology, redundant design technologies such as redundant excitation, dual channels and fault-tolerant teeth of stator permanent magnet brushless motor, fault-tolerant control technologies such as magnetic field reconstruction and harmonic injection, and multi excitation source design and magnetic field regulation technologies and methods

at present, the project has been authorized with more than 30 invention patents. The results of the project have been successfully applied to electric vehicles, elevators, generator sets and other aspects, and achieved good economic and social benefits. It has been cited and positively evaluated by famous scholars from 43 countries and regions

achievement transformation boosts the development of electric vehicles

at present, the development of new energy vehicle technology and industry is in the overall acceleration period and (3) the application of intellectual property in the field of civil new materials in the field of national defense; In the period of industrial reform, for the developing Chinese new energy vehicle industry, only by grasping the core technology can we have the capital to compete with foreign counterparts

the predecessor of Zhidou electric vehicle is xindayang Electromechanical group. In 2015, xindayang Electromechanical group, together with Geely Holding Group and Jinshajiang capital, jointly established Zhidou Electric Vehicle Co., Ltd., which is committed to the innovation and reform of human traffic ecology and focuses on the R & D and manufacturing of "micro pure electric vehicles". After decades of technical precipitation of New Ocean Electromechanical group, Zhidou electric vehicle has absorbed and transformed the research results of the project "key technologies and applications of strong fault tolerance and wide speed regulation permanent magnet motor", which has greatly improved the driving performance of Zhidou electric vehicle, and has made contributions to the improvement of the comprehensive performance of motor products such as the power density, fault tolerance and speed regulation range of permanent magnet motor in the industry. With the new energy electric vehicle in full swing, Zhidou electric vehicle has gained many praises in the industry and market through forward development, top-level design, and advanced core technology of electric vehicle

it is by no means overnight to develop such a world-leading innovative technology. It is reported that this project has lasted for several years, including Cheng Ming, professor and doctoral supervisor of the school of electrical engineering of Southeast University, Zhu Xiaoyong, Professor of Jiangsu University, Hua Wei, PhD, deputy director of the Department of motor and control of the school of electrical engineering of Southeast University, professor and doctoral supervisor of Jiangsu University, Bao Wenguang, chairman of New Ocean Electromechanical group Co., Ltd. and President of Zhidou Electric Vehicle Co., Ltd., associate professor of Nanjing University of Aeronautics and Astronautics Dr. Cao ruiwu worked together, pouring the hard work and sweat of many scientific researchers

with the adjustment and improvement of the subsidy policy for the promotion and application of new energy vehicles from January 1, 2017, China's electric vehicle industry has gradually entered the post subsidy era. At the same time, many foreign vehicle enterprises have been prepared for large-scale transformation and gradually shifted their R & D investment to new energy vehicles. The global industrial competition will become increasingly fierce. Only by mastering the core technology of independent research and development, can Chinese car enterprises win a place in the fierce competition in the future
