Analysis of the Application Status of Drive Motor System in my country
2021-09-15
The drive motor system is one of the core components of new energy vehicles. The motor drive control system is the main execution structure in the driving of the new energy vehicle, and its driving characteristics determine the main performance indicators of the vehicle driving. It is an important part of the electric vehicle.
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 promulgation of the national "Automobile Industry Adjustment and Revitalization Plan" in 2009, and the expansion of the State Council's plan from ten cities and a thousand vehicles to According to the discussion draft of the National Twelfth Five-Year Development Plan, there will be 10,000, 1,000,000 new energy vehicles by 2010, 2015 and 2020, respectively, and the scale of new energy vehicles and related industries will be formed. The development strategy has been upgraded to a national strategy, bringing opportunities for the development of the new energy vehicle industry and key accessories industry, and bringing a wide market space for environmentally friendly and energy-saving automotive power motors and drive system products.
Electric drive systems are widely used in automotive systems, bringing benefits to electric motor manufacturers. According to a new report from IMSResearch, between 2012 and 2017, the shipments of permanent magnet brushless DC motors used in the automotive industry will exceed those of DC servo motors and stepper motors. Permanent magnet brushless DC motor shipments will increase by 52%, and sales will exceed 462 million units.
From October 30th to 31st, 2013, the China Automotive Motor Technology and Application Forum was held in Shanghai, hosted by China Automotive Consulting Center Network, China Europe Alumni Automotive Industry Club, and Jiazhidao Automotive Consulting (Shanghai) Co., Ltd. The forum will focus on new market opportunities, performance improvement of motor parts and quality control of its own speeches and discussions. Looking forward to your attention and participation.
Motor parts technology may become a hot spot in the industry
Due to the shortage of energy and the increasing environmental pollution, electric vehicles have shown strong vitality and are generally favored by automobile manufacturers and consumers. Some data show that by 2010, electric vehicles will account for a quarter of the global demand for automobiles, and the total number will reach 20 million. American General Motors, Japan's Toyota, France's Citroen and other major car companies have taken electric vehicles as their development direction.
my country also attaches great importance to this. Electric vehicles have been listed by the Ministry of Science and Technology as a major national key project during the 10th Five-Year Plan period, and it is also one of the important contents of the development of green transportation in the 11th Five-Year Plan. Therefore, the motor industry has huge market potential.
For the current motor development, the technical upgrade of key components is extremely important to improve its reliability and life. At the China Automotive Motor Technology and Application Forum, China Automotive Consulting Center Network invited experts from Dayang Electric New Power Technology Co., Ltd., Delphi Packer Electrical Systems Co., Ltd., Schaeffler Group and other related companies to discuss the key internal aspects of the motor. New technologies for components and materials were introduced and discussed, and a series of solutions for improving the performance of key components were shared.
Permanent magnetization is the future development direction of electric motors. In terms of electric vehicle motor drive technology, due to the constraints of vehicle space and use environment, the motor drive system for electric vehicles is different from ordinary electric drive systems. It requires higher performance and higher volume/weight density. High temperature 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 future automotive motors.
Permanent magnet motors have the advantages of high efficiency, large specific power, high power factor, high reliability and easy maintenance. The frequency conversion speed regulation system of vector control can make the permanent magnet motor have a wide speed regulation range. Therefore, the permanent magnetization of the motor has become one of the important development directions of the motor drive technology.
At this forum, relevant experts from China Association of Automobile Manufacturers Automotive Electric Motors Committee, Changan Automobile Co., Ltd. and other companies delivered speeches, respectively on the penetration rate and market potential of permanent magnet motors in the automotive industry, and the prospects for permanent magnet drive motors. The performance improvement methods are introduced and analyzed.
