With the widespread use of energy-efficient motors in automobiles, agriculture, air conditioners and washing machines, the global motor market has grown greatly. According to MarketsandMarkets statistics, the size of the global motor market in 2019 was US$122 billion. Due to the impact of the Covid-19, the market size in 2020 has declined, and it is expected to be US$113.3 billion this year.

This is some changes in the global motor market this year. First of all, due to the impact of the Covid-19, the motor supply chain will be affected in the short term, because the motor parts actually come from China, the United States, Europe and other countries and regions. China has been effectively controlled, but there are still no signs of ending the epidemic in some countries and regions. Second, during the epidemic, the supply and demand in the motor market was actually somewhat out of balance. In addition, the exchange rates of various countries have been extremely unstable this year, and the changes have been relatively large. The cost of parts purchased in US dollars has increased.

BLDC motor market scale

Compared with the history of motors, BLDC is actually relatively young, with a history of more than 50 years since its development. However, with the development of semiconductor technology and the popularity of MCUs and drive components, the overall cost of BLDC motors has been reduced a lot. Therefore, BLDC motors have been developed in recent years, and their overall growth rate is also higher than that of motors.

Although the overall scale of global motors will decline in 2020, the market scale of BLDC has not declined, but has increased. According to statistics from Grand View Research, the market size of BLDC in 2019 is $16.3 billion, and the market size this year is expected to be $17.3 billion, and it will continue to grow at a compound annual growth rate of 6.5% in the future.

What about the situation of China's BLDC market? According to Frost & Sulivan's forecast, the average annual growth rate of China's BLDC motor market will reach 15% from 2018 to 2023, and the average annual growth rate of the BLDC controller market will reach 15.5% from 2018 to 2023.

Reasons for BLDC growth

Why is the growth rate of BLDC motors so high? We summarized the following four reasons:

One is determined by the characteristics of the BLDC motor itself.

BLDC motor is a new type of mechatronics motor that has emerged with the development of semiconductor electronic technology. It is a combination of modern electronic technology, including power electronics, microelectronics technology, control theory and motor technology.

It has superior speed regulation performance, which is manifested in good control performance, wide speed regulation range, large starting torque, good low-speed performance, stable operation, high efficiency, and its wide range of applications from industry to civilian use.

The second is the promotion of IE3 energy efficiency rating standards.

At present, the efficiency level of mainstream high-efficiency motors on the market is IE3, which can increase the energy efficiency by 4% compared with ordinary motors. The United States and Canada have already mandated industrial motors to meet IE3 energy efficiency standards in 2011 and 2012 respectively. The domestic and EU regions are relatively lagging behind, and in 2016 and early 2017, the IE3 energy efficiency rating standard was also promoted. The average price of IE3 high-efficiency motors is about 15% higher than that of ordinary motors. Therefore, at the beginning of implementation, the replacement is relatively slow. However, as the national environmental protection supervision measures become more stringent, and the reduction of energy consumption of high-efficiency motors can bring real benefits. The proportion is gradually increasing. It is estimated that China has introduced a new national standard this year, stipulating that the IE3 energy efficiency standard will be formally implemented after June 31, 2021.

The third is that the country attaches great importance to the development of the motor industry.

High-efficiency motors are the key industries supported by the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the National Development and Reform Commission and the State Council. Important development plans over the years have all regarded high-performance motors and their drive systems as key areas of national development. For example, in 2011, the policy of accelerating the large-scale application of domestic high-efficiency motors, the "Twelfth Five-Year" energy-saving and environmental protection industry plan in 2012; the Made in China 2025 in 2015, etc. all put the motor industry in key development areas.

The fourth is technological progress, and the price of BLDC motors has begun to be accepted by the market.
