Increasing Economic Pressure To Promote Efficient Energy-saving Motor Urgent
- Nov 16, 2017 -

Under the circumstance of increasing downward pressure on the economy, the pressure and challenges on the part of industrial enterprises have been aggravated. Large amount of motor, low energy efficiency, but also restricted the healthy development of the domestic economy. Therefore, promotion of high-efficiency and energy-saving motors has become an urgent task. This is not only an urgent need for industrial enterprises to adapt to social development, but also an inevitable requirement for domestic motor products to keep up with the international trend of development. It is also conducive to promoting technological progress and product exports.


    Increasing economic pressure to promote efficient energy-saving motor urgent


    Industrial transformation and upgrading for the motor industry has brought tremendous room for development. It is estimated that by 2020, the installed capacity of motor in China will reach 2.5 billion KW and the total installed capacity of 800 million KW will be added in the next five years.


    According to statistics, in 2015, China's motor ownership was about 2.4 billion kilowatts, with a total power consumption of 3.5 trillion kwh and a total social electricity consumption of 5.55 trillion kilowatt hours, accounting for 65% of the total electricity consumption of the whole society; In the industrial sector, the total power consumption of the motor is 2.9 trillion kwh and the industrial electricity consumption is 3.93 trillion kwh, accounting for 74% of the industrial electricity consumption, while the consumption of the industrial motor accounts for 52% of the total electricity consumption of the whole society.


    Under the circumstance of increasing downward pressure on the economy, the pressure and challenges on the part of industrial enterprises have been aggravated. Large amount of motor, low energy efficiency, but also restricted the healthy development of the domestic economy. Therefore, promotion of high-efficiency and energy-saving motors has become an urgent task. This is not only an urgent need for industrial enterprises to adapt to social development, but also an inevitable requirement for domestic motor products to keep up with the international trend of development. It is also conducive to promoting technological progress and product exports.


    The motors are widely used in the industrial field. As the driving devices of various machinery and equipment such as fans, pumps, compressors, machine tools and transmission belts, their power consumption accounts for more than 60% of the total industrial power consumption in China. Among them, the small three-phase asynchronous motor About 35% of power consumption is a big power consumer. Therefore, developing an efficient electric motor in China is one of the important measures to improve energy efficiency and is in line with the needs of our country's development. It is very necessary.


    Motor system energy-saving project is the focus of national energy-saving emission reduction work. In the context of energy saving and emission reduction, mandatory standards and encouragement policies determine the future of energy-efficient motors will fully replace the traditional inefficient motors, energy-efficient motor is a new motor design, new technology and new materials, by reducing the electromagnetic energy, heat and mechanical energy Loss, improve the motor output efficiency of the motor.


    "Green, environmental protection, low-carbon" energy-efficient products is the trend. "According to the total installed capacity of 2.5 billion KW to calculate, if the energy efficiency of all motors increased by 5 percentage points, then you can build a lot less power stations, the overall social emissions of carbon can also be greatly reduced.


    Compared with common standard motors, the energy-saving effect of using energy-efficient motors is very obvious. Under normal circumstances, the average energy consumption is reduced by about 10%, and the efficiency can be increased by about 4%. Expert analysis, the motor's entire life cycle, the purchase price of motor 2% of the total cost of maintenance costs accounted for 0.7% of its total cost, while the cost of energy accounted for 97.3% Therefore, from the entire life cycle of the motor Consider, from the motor design, manufacture to motor selection, operation, regulation, overhaul, scrap, energy-efficient motors for the factory to save energy, reduce life-cycle operating costs, improve production efficiency and reduce environmental pollution, but also reduce energy Consumption and lower carbon dioxide emissions are conducive to the sustainable development of the factory. In short, the effect of energy saving is sustainable throughout the entire life cycle of the machinery and equipment.


    According to statistics, every percentage point improvement in motor energy efficiency in the industrial area can save about 26 billion kilowatt-hours of electricity annually. Through the improvement of energy efficiency, the overall efficiency of the motor system can be increased by 5-8 percentage points. Annual savings of 1300-300 billion kilowatt hours can be achieved, equivalent to 2-3 generating capacity of the Three Gorges Power Station.


    Efficient motor promotion dates back to 2007. In 2008, China listed the motor system energy conservation as one of the top ten energy-saving projects in China. In 2009, it included the application of highly efficient and ultra-efficient electric motors in the Huimin project. It issued a circular on June 2, 2010, saying that energy- Products Huimin project scope of implementation, so that efficient motor marketing attracted much attention.


    Highly efficient and energy-saving motor is very suitable for textile, fan, water pump, compressor, rely on electricity for about two years to recover the motor purchase costs. Select efficient motor, energy-saving effect is obvious, generally 1 to 2 years to recover all the investment in motor replacement. The electrical equipment like the general service life of transformers for decades, with high efficiency motor instead of high energy consumption motor, not only can improve energy conversion efficiency, but also in the life saving effect is quite significant, providing long-term development of the factory to provide a huge impetus.
