In an environment of increasing downward pressure on the economy, the pressures and challenges faced by industrial enterprises are increasing. The large amount of electric motors and low energy efficiency also restrict the healthy development of the domestic economy. Therefore, it is urgent to promote high-efficiency energy-saving motors. This is not only for industrial enterprises to adapt to the needs of social development, but also an inevitable requirement for domestic motor products to keep up with the international development trend. At the same time, it is also conducive to the advancement of industry technology and product exports.
　　The downward pressure on the economy is increasing. It is urgent to promote high-efficiency and energy-saving motors
　　The transformation and upgrading of industry has brought huge development space for the motor industry. It is estimated that by 2020, the installed capacity of electric motors in my country 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 statistical calculations, in 2015, my country's motor ownership was about 2.4 billion kilowatts, and the total power consumption was about 3.5 trillion kilowatt hours. The electricity consumption of the whole society was 5.55 trillion kilowatt hours, accounting for 65% of the total electricity consumption of the whole society; The total power consumption of industrial motors is 2.9 trillion kWh, and the industrial power consumption is 3.93 trillion kWh, accounting for 74% of industrial power consumption, and industrial motor power consumption accounts for 52% of the total power consumption of the society.
　　In an environment of increasing downward pressure on the economy, the pressures and challenges faced by industrial enterprises are increasing. The large amount of electric motors and low energy efficiency also restrict the healthy development of the domestic economy. Therefore, it is urgent to promote high-efficiency energy-saving motors. This is not only for industrial enterprises to adapt to the needs of social development, but also an inevitable requirement for domestic motor products to keep up with the international development trend. At the same time, it is also conducive to the advancement of industry technology and product exports.
Motors are widely used in industrial fields, as the driving device of various mechanical equipment such as fans, pumps, compressors, machine tools, conveyor belts, etc. Its power consumption accounts for more than 60% of China's entire industrial power consumption. Among them, small three-phase asynchronous motors Electricity consumption accounts for about 35%, which is a large consumer of electricity. Therefore, the development of high-efficiency motors in China is one of the important measures to improve energy efficiency. It is necessary to meet the needs of my country's development.
　　The energy-saving project of the motor system is a key area of ​​the national energy-saving and emission-reduction work. In the context of energy conservation and emission reduction, mandatory standards and encouraging policies determine that high-efficiency energy-saving motors will fully replace traditional low-efficiency motors in the future. High-efficiency energy-saving motors adopt new motor design, new technology and new materials, and reduce electromagnetic energy, thermal energy and mechanical energy. Loss, improve the output efficiency of the motor.
　　 "Green, environmentally friendly, low-carbon" high-efficiency and energy-saving products are the general trend. "Calculated based on the total installed capacity of 2.5 billion KW, if the energy efficiency value of all motors is increased by 5 percentage points, then a lot of power stations can be built less, and the overall social carbon emissions can also be greatly reduced." Zhejiang Jinlong Electric Co., Ltd. Chairman Ye Jinwu said, "At present, our annual production and sales are 700 million to 800 million yuan, of which ultra-efficient motors account for an increasing proportion. In 2015, the proportion increased by 30% compared to 2014, and now it accounts for more than 70% of overall sales. NS."
　　 Compared with ordinary standard motors, the energy-saving effect of using high-efficiency energy-saving motors is very obvious. Under normal circumstances, the energy consumption is reduced by about 10% on average, and the efficiency can be increased by about 4%. Expert analysis shows that during the entire life cycle of a motor, its purchase price accounts for 2% of the total cost of the motor, maintenance costs account for 0.7% of its total cost, and energy consumption costs account for 97.3%. Therefore, from the entire life cycle of the motor Consider that from the design and manufacture of the motor to the selection, operation, adjustment, maintenance, and scrapping of the motor, high-efficiency and energy-saving motors can save energy for the factory, reduce life cycle operating costs, improve production efficiency, reduce environmental pollution, and reduce energy. Consume and reduce carbon dioxide emissions, which is conducive to the sustainable development of the factory. In short, the effect of energy saving can continue throughout the entire life cycle of mechanical equipment.
　　According to statistics, every 1% increase in the energy efficiency of motors in the industrial sector 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 improved by 5-8%. It can save 130-230 billion kilowatt-hours of electricity annually, which is equivalent to the power generation of 2-3 Three Gorges power stations.
　　 The promotion of high-efficiency motors can be traced back to 2007. my country listed the energy saving of motor systems as one of the top ten national energy-saving projects in 2008. In 2009, the application of high-efficiency and ultra-efficient motors was included in the Huimin Project. On June 2, 2010, a notice was issued stating that high-efficiency motors will be included in energy-saving projects. The scope of implementation of the product benefiting project has attracted much attention to the market promotion of high-efficiency motors.
　　 High-efficiency and energy-saving motors are very suitable for textiles, fans, pumps, and compressors. The purchase cost of motors can be recovered by saving electricity for about two years. Choosing a high-efficiency motor has obvious power-saving effects. Generally, the investment in all renewal motors can be recovered within 1 to 2 years. Electrical equipment, like transformers, has a service life of several decades. Using high-efficiency motors to replace high-energy-consumption motors can not only improve energy conversion efficiency, but also has significant effects in terms of life and power saving, providing a huge impetus for the long-term development of the factory.
