Motor field

China's motor production began in 1917, and the industry has formed a relatively complete industrial system in China. With the development of electric power, China's motor manufacturing industry has shown great vitality, and the production and marketing scale and economic benefits have been greatly improved.
From 2005 to 2011, the average annual sales revenue of China's motor manufacturing industry increased by 36.92%. In addition to the general decline of the manufacturing industry and the year-on-year growth rate of motors decreased to 11.20% in 2009 affected by the financial crisis, the market scale growth rate of motors in China was at a high level in other years, with a year-on-year growth rate of more than 20%. Even when the development speed of China's manufacturing industry generally slowed down in 2011, the year-on-year growth rate of motors still reached 21.87%.
Motor manufacturing enterprises should establish their own brands, develop high-end, 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, so as to remain invincible in the severe market competition.
In the whole society, about 70% of the power consumption is consumed in the industrial field, and the power consumption of industrial motors accounts for 70% of the power consumption of the whole industrial field. To improve the efficiency of the motor, there are two ways to improve the operation efficiency of the AC motor through a frequency converter; The second is to use high-efficiency motors. Different frequency converters are the main energy-saving in industrial fields. The energy-saving efficiency is generally more than 30%, and even as high as 40% - 50% in some industries. The market application proportion of high-efficiency motors is still relatively low, but with the support of * * energy efficiency standards and subsidy policies, the market application proportion of high-efficiency motors will increase significantly in the future.
From January to December 2012, China exported 3.096 billion motors and generators, a decrease of 8.2% compared with the same period in 2011, and the cumulative export amount reached US $9.224 billion, a year-on-year increase of 5.0%. China exported 74.8 billion US dollars and 1.8 billion electric motors in the same month. In terms of investment, the layout should be made in advance before the introduction of favorable policies. The market application proportion of high-efficiency motors is still low, but with the support of * * energy efficiency standards and subsidy policies, the market application proportion of high-efficiency motors will increase significantly in the future. Motor system includes control device, motor, driven device, transmission device and pipe network load. It is a complex system involving multiple disciplines, disciplines and fields.
Strategic emerging industries, contract energy management policies, the construction of market-oriented energy conservation and environmental protection service system, comprehensive utilization and remanufacturing of resources and the promotion of high-efficiency motors of energy-saving products benefiting the people have brought major opportunities for the development of the motor industry. Related motor manufacturers and motor supporting enterprises have also ushered in the market growth potential of product upgrading. Especially in order to adapt to the trend of energy-saving technology innovation in the era of low-carbon economy, high-efficiency motors have gradually become the mainstream of the future market.
The annual power consumption of electric machines in China exceeds 2 trillion kwh, accounting for about 60% of the national power consumption and 80% of the industrial power 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 a certain significance for the country to promote energy conservation and emission reduction, and its potential market opportunities are also emerging.
