Development Status and Future Trend Analysis of Brushless Motor Industry
Brushless motor industry development status
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. 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.
