The production of electric motors in my country began in 1917, and the industry has formed a relatively complete industrial system in China. With the development of electric power, my country's electric motor manufacturing industry has shown great vitality, and the scale of production and sales and economic benefits have been greatly improved.
From 2005 to 2011, the sales revenue of my country's electric motor manufacturing industry increased by 36.92% annually. Except in 2009, which was affected by the financial crisis, the manufacturing industry generally declined, and the year-on-year growth rate of electric motors dropped to 11.20%. In 2011, when the development of my country's manufacturing industry generally slowed down, the year-on-year growth of electric motors still reached 21.87%.
Motor manufacturing enterprises should establish their own brands, develop 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 remain invincible in the severe market competition. land.
About 70% of the power consumption in the whole society is consumed in the industrial field, and the power consumption of industrial motors accounts for 70% of the power consumption in the entire industrial field. There are two main ways to improve motor efficiency, through a frequency converter, to improve the operating efficiency of AC motors; 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 above 30%, and even as high as 40%-50% in some industries. The market application ratio of high-efficiency motors is still relatively low, but with the support of minimum energy efficiency standards and subsidy policies, the market application ratio of high-efficiency motors will increase significantly in the future.
From January to December 2012, my country exported a total of 3.096 billion electric motors and generators, a decrease of 8.2% compared with the same period in 2011, and the cumulative export value reached 9.224 billion US dollars, a year-on-year increase of 5.0%. In December, the export volume of my country's electric motors and generators was 274.8 million units, and the export value was 818 million US dollars. In terms of investment, it should be deployed in advance before the introduction of favorable policies. The market application ratio of high-efficiency motors is still low, but with the support of minimum energy efficiency standards and subsidy policies, the market application ratio of high-efficiency motors will increase significantly in the future. The motor system includes control devices, motors, driven devices, transmission devices, and pipe network loads. It is a complex system involving multiple disciplines, multiple disciplines, and multiple fields.
Strategic emerging industries, contract energy management policies, market-oriented energy-saving and environmental protection service system construction, comprehensive utilization of resources and remanufacturing, and energy-saving products Huimin Project, the promotion of high-efficiency motors has brought major opportunities for the development of the motor industry, and related motor manufacturers And motor supporting enterprises also ushered in the market growth potential of product upgrading. Especially in order to adapt to the innovation trend of energy-saving technology in the era of low-carbon economy, high-efficiency motors have gradually become the mainstream of the future market
