An electric machine is an electromagnetic mechanical device that utilizes the interaction of electricity and magnetism to achieve energy conversion and transmission. The generalized motor includes an electric motor and a generator. The electric motor absorbs electric energy from the electric system and outputs mechanical energy to the mechanical system. Various types of electric motors are widely used in various sectors of the national economy as well as household appliances, mainly as the driving force for various mechanical equipment; the generator absorbs mechanical energy from the mechanical system, and the electric power The system's output of electrical energy, technological advances in generators and other related equipment, enables people to use heat, water, nuclear energy, and wind, solar, biomass and other energy sources to generate electricity, to provide the necessary energy to all sectors of the national economy and the majority of urban and rural residents.
After years of development, China's motor industry has formed a certain industrial base and industry structure, and has reached a certain scale of production. The barriers to entry have been significantly improved compared with the previous period. According to the statistics of the National Bureau of Statistics, in 2016, the number of enterprises in the motor manufacturing industry in China was 2,849.
In the entire motor industry, AC motors account for the vast majority of production. According to the specific data, from 2008 to 2016, the growth rate of China's AC motor production was affected by the macro economy, and the fluctuation was more obvious. In 2016, China's AC motor production was 278 million kilowatts, down 1.7% year-on-year.
Numerous motors are “newcomers” in the motor industry. The history of entering the country is not long, and the price is higher than that of brushed motors. However, due to the obvious advantages of brushless motors, the development momentum is rapid. After entering China, it was quickly favored by industries such as home appliances, automobiles, ships and machinery, and occupied a place in various industries and developed rapidly. According to the statistics of the National Bureau of Statistics, since 2010, the revenue of the brushless motor industry has increased year after year, reaching 18.92 billion yuan in 2016, an increase of 22.3%.
With the improvement of people's living standards and the development of modern production and office automation, household appliances, industrial robots and other equipment are becoming more and more efficient, miniaturized and highly intelligent. As an important part of the actuators, the motor must be With high precision, high speed and high efficiency, the application of DC brushless motor has also grown rapidly. At this stage, although various AC motors and DC motors are dominant in transmission applications, DC brushless motors are receiving widespread attention. In the next few years, the market prospect of China's DC brushless motors is more optimistic.
Future trends in the brushless motor industry
First, the market scale has further expanded. Because of the high price and high cost for large-scale application, many companies are discouraged and prefer to use brushed motor products as an alternative. Therefore, the potential demand for brushless motors has not been fully released, and there is still plenty of room for development in the future. Looking forward to the forecast, in the next five years, the industry growth rate will remain at around 20%. By 2022, the industry market will reach about 56.5 billion yuan.
Second, the level of competition will increase. At present, there are many enterprises that do brushless motors, but there are still a few enterprises that have reached a certain scale. According to the statistics of the National Bureau of Statistics, in 2016, there were only about 118 enterprises above the scale in the brushless motor industry in China. However, with the bright future of the brushless motor industry, more motor companies are expected to enter the field in the future, thus intensifying market competition.
Third, the technical water has improved steadily. In the brushless motor industry, the technical level determines the market expansion capabilities of the company's products. However, the brushless motor technology is more complicated, especially in the control system of the brushless motor, how to convert the sense into a non-inductive or weak magnetic brushless motor is a technically difficult problem to solve. Moreover, in the high-end brushless motor products, the core chip technology is still controlled by foreign countries, and China still relies on imports. Therefore, increasing R&D investment and improving the technical level are the top priorities for the future development of brushless motors.
Fourth, the degree of integration and diversification has increased. The expansion of the application field has continuously promoted the technical level of brushless motor products. Enterprises with strong technical strength in the industry continue to develop new products and enhance the application fields of the products. The application of diversification in the industry is gradually advanced. In terms of integration, since the industry products are subject to the upstream, the willingness to integrate the industry is strong, but it is limited by the size of the individual enterprises, and the degree of integration is still low.
