The production of electric motors in our country began in 1917, and the industry has already formed a relatively complete industrial system in China. The electric motor manufacturing industry in China has shown great vitality with the development of electricity, with significant improvements in production and sales scale and economic benefits.

From 2005 to 2011, the annual sales revenue of China's electric motor manufacturing industry increased by 36.92%. Except for 2009, which was affected by the financial crisis and the manufacturing industry generally declined, the year-on-year growth rate of electric motors decreased to 11.20%. In other years, the market size growth rate of electric motors in China was at a relatively high level, with a year-on-year growth rate of over 20%. Even though the development speed of China's manufacturing industry generally slowed down in 2011, the year-on-year growth rate of electric motors still reached 21.87%.

Motor manufacturing enterprises should establish independent brands, focus on high-end products, expand overseas markets, ensure product quality and after-sales service, and develop into new fields such as aviation, navigation, military industry, nuclear power, and special motors in order to stand invincible in the fierce market competition.

About 70% of the total electricity consumption in society is in the industrial sector, and industrial motors account for 70% of the total electricity consumption in the industrial sector. There are two main ways to improve motor efficiency: using a frequency converter to improve the operational efficiency of an AC motor; The second is to use high-efficiency motors. Different frequency converters are the main energy-saving methods in the industrial field, with energy efficiency generally exceeding 30%, and in some industries even reaching as high as 40% -50%. The market application proportion of high-efficiency motors is still relatively low, but with the support of lower energy efficiency standards and subsidy policies, the market application proportion of high-efficiency motors will significantly increase in the future.

From January to December 2012, China exported a total of 3.096 billion electric motors and generators, a decrease of 8.2% compared to the same period in 2011. The cumulative export amount reached 9.224 billion US dollars, a year-on-year increase of 5.0%. In December, the export volume of electric motors and generators in China was 274.8 million units, with an export value of 818 million US dollars. In terms of investment, we should plan ahead before the favorable policies are introduced. The application proportion of high-efficiency motors in the market is still relatively low, but with the support of lower energy efficiency standards and subsidy policies, the market application proportion of high-efficiency motors will significantly increase in the future. The motor system includes control devices, electric motors, driven devices, transmission devices, and pipeline loads, and is a complex system involving multiple disciplines, specialties, and fields.

The strategic emerging industries, contract energy management policies, market-oriented energy-saving and environmental protection service system construction, comprehensive utilization and remanufacturing of resources, and the promotion of high-efficiency motors for energy-saving products have brought significant opportunities for the development of the motor industry. Motor manufacturers and supporting enterprises related to them have also ushered in market growth potential for product updates and upgrades. Especially to adapt to the trend of energy-saving technology innovation in the low-carbon economy era, high-efficiency motors have gradually become the mainstream of the future market.

The annual electricity consumption of electric motors in China exceeds 2 trillion kilowatt hours, accounting for approximately 60% of the national electricity consumption and 80% of industrial electricity consumption. The energy consumption of high-efficiency motors is 20%~30% lower than that of ordinary motors, but the market share of high-efficiency motors in China is only 10%. Therefore, vigorously promoting high-efficiency motors will have certain significance for the country to promote energy conservation and emission reduction, and its potential market opportunities are also emerging.
