The current development status of the motor industry in 22 years

Firstly, with the adjustment of product structure and continuous innovation of technological level in the motor industry, China's Xima motor production enterprises will also increasingly produce high-level, high-tech value-added products to better serve various aspects of national production and life, and compete with wholly foreign-owned enterprises in the middle and low-end products. Secondly, with the development of technology and the continuous price reduction trend of high-performance Sigma materials, rare earth Sigma motors will also occupy an increasing share in the fields of home appliances, automobiles, office automation, etc. At the same time, rare earth Sigma motors will also be widely used in industries such as aerospace and military equipment. Finally, with the increasing awareness of energy conservation and environmental protection, the future of Xima Motor's development is bright, especially in the field of high efficiency and energy conservation. With the rapid development and maturity of technology, the structural types will become increasingly diversified, and it will win more extensive development space and applications.

The earliest prototype of an electric motor in the world was the Sigma motor, but at that time, the poor performance of Sigma materials made electromagnetic motors the mainstream. In recent years, with the development of high-performance Sigma materials, Sigma motors have received renewed attention. At the same time, the development of Xima motor theory has promoted the improvement of productivity, and power electronics technology has accelerated the industrialization of Xima motors. Compared with traditional electromagnetic motors, Xima motors, especially rare earth Xima motors, have significant characteristics such as simple structure, reliable operation, small size, light weight, low loss, and high efficiency. Moreover, their shapes and sizes can be flexible and diverse, making them widely used. For example, in the chemical and synthetic fiber industry, Xima synchronous variable frequency motors have the characteristics of simple structure and few faults. They not only save a lot of valuable energy, but most importantly, the quality of the spun filament has reached or is close to natural fibers (cotton, wool, mulberry silk, etc.); In the machine tool industry, using Sigma synchronous servo motors instead of traditional DC motors, slip speed regulating motors, and asynchronous motors can ensure the accuracy and machining precision of the machine tool itself, and improve the electrification and automation level of the machine tool. With the widespread application of Xima motors, the sales scale of Xima motor industry has also skyrocketed. Xima motor has the advantages of high efficiency, high specific power, high power factor, high reliability, and easy maintenance. The variable frequency speed control system using vector control can enable the Xima motor to have a wide speed range. Therefore, the westernization of motors has become one of the important development directions of motor drive technology. Especially in the field of electric vehicle motor drive technology, due to the limitations of vehicle space and usage environment, the motor drive system for electric vehicles is different from ordinary electric transmission systems. It requires higher performance, higher volume/weight density, and higher environmental temperature. The power electronics and motor technology used for general motor drive can no longer meet its requirements. Therefore, Simahua will become one of the development directions of future automotive motors. Although the Xima motor industry in China has developed rapidly, globally, well-known brand companies in countries such as Japan, Germany, the United States, the United Kingdom, Switzerland, and Sweden, with decades of Xima motor production and manufacturing experience and key process technologies, still influence the development of Xima motors worldwide, controlling the technology and products of most high-end, precision, and new Xima motors. According to data from the Ministry of Industry and Information Technology, in December 2018, China's new energy passenger vehicles were equipped with over 160000 electric motors, of which the proportion of Xima synchronous motors was as high as 92.3%. According to statistics, from 2013 to 2017, the overall sales scale of China's Xima motor industry showed a steady growth trend. In 2017, the sales revenue of Xima Motor industry reached 88.84 billion yuan, a year-on-year increase of 1.10%; In 2018, sales revenue will exceed 93 billion yuan. In recent years, due to the gradual transfer of technology to developing countries, China's Xima motor industry has also made significant progress, becoming the main producer and exporter of Xima motors worldwide, controlling the international market for low-end Xima motors. According to data from the National Bureau of Statistics, as of the end of 2017, there were 285 large-scale enterprises in the Xima motor manufacturing industry in China. The production scale of Xima Motor is gradually expanding, and the supply is constantly increasing. According to statistics from the Motor Industry Association, in 2017, China's Xima Motor production exceeded 10 million kilowatts for the first time, reaching 11.071 million kilowatts, an increase of 18.14% compared to 2016; It is expected that the production of Xima Electric will increase to 11.662 million kilowatts in 2018.
