Motor parts technology or industry hot spots

The drive motor system is one of the core components of new energy vehicles. The motor drive control system is the main executive structure of the new energy vehicle. Its driving characteristics determine the main performance indicators of the car. It is an important part of the electric vehicle.

The permanent magnet synchronous motors and drive systems used in pure electric and hybrid vehicles have reached the stage of market application, with the introduction of the national "Auto Industry Adjustment and Revitalization Plan" in 2009, and the State Council's plan of "Ten Cities and Thousands". It has been expanded to “a thousand cars in Fucheng”, and according to the draft of the “12th Five-Year Development Plan” of the country, it shows that by 2010, 2015, and 2020, the scale of 10,000, one million, and ten million new energy vehicles will be formed respectively. The development strategy for new energy vehicles and related industries has risen to the national strategy, which has brought opportunities for the development of the new energy automotive industry and key accessories industry, and has brought a wide market space for environmental protection and energy-saving automotive power motor and drive system products.

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

On October 30-31, 2013, the "China Automotive Motor Technology and Application Forum" hosted by the China Automotive Consultation Center, China-EU Alumni Automobile Industry Club and Jiazhidao Automotive Consulting (Shanghai) Co., Ltd. was held in Shanghai. . The forum will focus on new market opportunities, performance improvements of motor parts and parts, and quality control. Look forward to your attention and participation.

Due to the increasing energy shortage and environmental pollution, electric vehicles show strong vitality and are generally favored by automobile manufacturers and consumers. According to statistics, by 2010, electric vehicles will account for a quarter of global vehicle demand, and the total volume will reach 20 million. U.S. GM, Japan’s Toyota, and France’s Citroen have all adopted electric vehicles as their development direction.

China also attaches great importance to this, electric vehicles have been listed by the Ministry of Science and Technology during the "Tenth Five-Year Plan" national key projects, but also the "Eleventh Five-Year Plan" in the development of green traffic, one of the important content. Therefore, the motor industry has great market potential.

For the current motor development, the technical upgrading of key components is extremely important to improve its reliability and longevity. At the China Automotive Motor Technology and Application Forum, the China Automotive Consultation Center has invited experts from related companies such as Dayang Electric New Power Technology Co., Ltd., Delphi Pike Electrical Systems Co., Ltd., and Schaeffler Group to discuss the key zero within 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 direction of motor development

In the field of electric vehicle motor drive technology, the motor drive system for electric vehicles is different from the ordinary electric drive system due to vehicle space constraints and the constraints of the use environment. It requires higher performance, higher volume/weight density, and higher ambient temperature. Power electronics and motor technology used for general motor drive have not been able to adapt to their requirements. Therefore, permanent magnetization will become one of the directions for the development of automotive motors in the future.

Permanent magnet motors have the advantages of high efficiency, high specific power, high power factor, high reliability and easy maintenance. The vector control of the variable frequency speed control system allows the permanent magnet motor to have a wide speed range. Therefore, the permanent magnetization of the motor becomes one of the important development directions of the motor drive technology.

At the forum, experts from companies such as the Automotive Electrical Appliances Committee of the China Association of Automobile Manufacturers and Changan Automobile Co., Ltd. delivered speeches, respectively, regarding the penetration rate and market potential of permanent magnet motors in the automotive industry, and the permanent magnet drive motors. Performance improvement methods were introduced and analyzed.
