It is urgent to promote efficient and energy-saving motors with increasing downward pressure in economy(Hits:) 
Origin Author Add Time2016-03-25 fontSize: T|T
With the increasing downward pressure of the economy, the pressure and challenges faced by industrial enterprises are becoming more and more serious. Large motor consumption and low energy efficiency also restrict the healthy development of domestic economy. Therefore, it is urgent to promote high efficiency and energy-saving motors. This is not only an inevitable requirement for industrial enterprises to adapt to the needs of social development, but also for domestic motor products to keep up with the international development trend. At the same time, it is also conducive to promoting industrial technological progress and product exports.
It is urgent to promote efficient and energy-saving motors with increasing downward pressure in economy
The transformation and upgrading of industry has brought tremendous space for the development of motor industry. It is expected that by 2020, the installed capacity of motor in China will reach 2.5 billion KW, and 800 million KW will be added in the next five years.
According to statistics, in 2015, China has about 2.4 billion kilowatt-hours of motor, and its total power consumption is about 3.5 trillion kilowatt-hours. The total social electricity consumption is 5.55 trillion kilowatt-hours, accounting for 65% of the total social electricity consumption. The total power consumption of motor in the industrial field is 2.9 trillion kilowatt-hours, industrial electricity consumption is 3.93 trillion kilowatt-hours, accounting for 74% of industrial electricity consumption, and industrial electricity consumption accounts for 52% of the total social electricity consumption.
With the increasing downward pressure of the economy, the pressure and challenges faced by industrial enterprises are becoming more and more serious. Large motor consumption and low energy efficiency also restrict the healthy development of domestic economy. Therefore, it is urgent to promote high efficiency and energy-saving motors. This is not only an inevitable requirement for industrial enterprises to adapt to the needs of social development, but also for domestic motor products to keep up with the international development trend. At the same time, it is also conducive to promoting industrial technological progress and product exports.
Motors are widely used in industrial fields. As the driving devices of various mechanical equipment such as fans, pumps, compressors, machine tools and conveyor belts, their power consumption accounts for more than 60% of the total industrial power consumption in China. Among them, small three-phase asynchronous motors account for about 35% of the total power consumption, which is a major power consumer. Therefore, the development of high-efficiency motors in China is one of the important measures to improve energy efficiency, which is in line with the development of China. Needs are very necessary.
Energy-saving engineering of motor system is the key field of energy-saving and emission reduction in our country. In the context of energy saving and emission reduction, compulsory standards and incentive policies determine that high-efficiency and energy-saving motors will replace traditional low-efficiency motors in the future. High-efficiency and energy-saving motors adopt new motor design, new technology and new materials to improve the output efficiency of motors by reducing the loss of electromagnetic, thermal and mechanical energy.
"Green, environmentally friendly, low-carbon" energy-saving products are the general trend. "According to the total installed capacity of 2.5 billion KW, if the energy efficiency of all motors is increased by 5 percentage points, many power stations can be built less, and the overall social carbon emissions can be greatly reduced." Ye Jinwu, chairman of Zhejiang Jinlong Electric Machinery Co., Ltd., said, "At present, we produce and sell 700-800 million yuan annually, of which the proportion of ultra-high efficiency motors is getting larger and larger. In 2015, the proportion increased by 30% compared with 2014, and now accounts for more than 70% of the total sales."
Compared with ordinary standard motors, the energy-saving effect of using high-efficiency energy-saving motors is very obvious. Usually, the average energy consumption decreases by about 10%, and the efficiency can be increased by about 4%. Expert analysis shows that in the whole life cycle of the motor, the purchase price accounts for 2% of the total cost of the motor, the maintenance cost accounts for 0.7% of the total cost, and the energy consumption cost accounts for 97.3%. Therefore, considering the whole life cycle of the motor, i.e. from the design and manufacture of the motor to the selection, operation, regulation, maintenance and scrap of the motor, high-efficiency and energy-saving motor can save energy for the factory. Reducing the cost of life cycle operation, improving production efficiency and reducing environmental pollution, reducing energy consumption and reducing carbon dioxide emissions are conducive to the sustainable development of factories. In a word, the effect of energy saving can be sustained throughout the whole life cycle of machinery and equipment.
According to statistics, every percentage point increase in energy efficiency of motor in industrial field can save about 26 billion kilowatt-hours of electricity annually. Through energy efficiency improvement, the overall efficiency of motor system can be improved by 5-8 percentage points. It can save 1300-230 billion kilowatt-hours of electricity in a year, equivalent to 2-3 generations of the Three Gorges Power Station.
The promotion of high efficiency motors can be traced back to 2007. In 2008, China listed the energy-saving of motor system as one of the ten national energy-saving projects. In 2009, the application of high-efficiency and ultra-high-efficiency motors was included in Huimin Project. On June 2, 2010, a notice was issued that high-efficiency Motors should be included in the implementation scope of Huimin Project, so that the market promotion of high-efficiency Motors has attracted much attention.
High-efficiency and energy-saving motor is very suitable for textile, fan, water pump, compressor. It can recover the cost of motor purchase by saving electricity for about two years. Selection of high-efficiency motors, energy-saving effect is obvious, generally within 1 to 2 years can recover all the investment in updating the motor. The service life of motor equipment, like transformer, lasts for decades. Replacing high-energy-consuming motor with high-efficiency motor can not only improve energy conversion efficiency, but also achieve remarkable results in life-saving and power-saving, which provides a huge impetus for the long-term development of factories.
