The development of high efficiency and energy saving electric power industry

Motor is an important industrial energy consumption equipment,widely used in areas such as

fan,compressor,pump,mechanical transmission,its power consumption is more than about 60% of China's entire industrial power consumption,small three-phase asynchronous motor power consumption accounts for about 35%,is a major drain,so the development of China's high efficiency motor is one of the important measures to improve energy efficiency,meet the needs of the development of our country,it is very necessary.Under the background of economic globalization,especially in the environment of the gasoline generator economic downturn,the stress in a number of industrial enterprises and the growing challenges encountered. Motor large dosage,low level of energy efficiency,but also restricted the healthy development of the

domestic economy.therefore,it is very urgent to promote high efficiency and energy saving motor has not only industrial enterprises to adapt to the demand of social development,but also make the products to keep up with the trend of international development,the inevitable requirement of domestic motor,as well as to promote the industry technology progress and product exports.

Energy conservation to reduce running cost for a long time Motor is an important industrial energy consumption equipment,widely used in areas such as fan,compressor,pump,mechanical transmission,its power consumption is more than about 60% of China's entire industrial power consumption,small three-phase asynchronous motor power consumption accounts for about 35%,is a major drain,so the development of China's high efficiency motor is one of the important measures to improve energy efficiency,meet the needs of the development of our country,it is very necessary.Motor system energy saving project has been listed as China's 11th five-year plan is one of the ten major energy conservation projects,is the key areas of the country's energy conservation and emissions induction motor price reduction work. In the context of energy conservation and emissions reduction,mandatory standards and encourage policy determines the high efficiency and energy saving motor will fully replace the traditional inefficient,high efficiency and energy saving motor is a new motor design,new technology and new materials,by reducing the wastage of the electromagnetic energy,heat energy and mechanical energy,improve the efficiency of the output of the motor of the motor.

Compared with standard motor,motor with high efficiency and energy saving and energy saving effect is very obvious,under normal circumstances,the average energy consumption fell by around 10%,efficiency can be increased by about 4%. Expert analysis,in the whole life cycle of the motor,the purchasing price accounted for 2% of the total cost of the motor maintenance costs accounted for 0.7% of its total cost,and the cost of energy consumption accounted for 97.3%. Therefore,considering from the whole life cycle of the motor,that is,from the design,manufacture of the motor to motor selection,operation,www.dongfeng-motor.com adjustment,repair,scrap,high efficiency and energy saving motor save energy consumption for the factory,reduce the life cycle cost and improve production efficiency and reduce environmental pollution,but also reduce energy consumption and reduce the emissions of carbon dioxide,conducive to the sustainable development of the factory. In short,the effect of energy saving for sustainable throughout the entire life cycle of mechanical equipment.The investment cost recovery fast economic potential High efficiency and energy saving motor is very suitable for textile,fan,water pump,compressor,by recoverable motor acquisition cost electricity saving about two years. 

For example: a rated power is 7.5 kw,the energy efficiency of grade 3 of Y2-132 - m - 4 change into the same rated power,the energy efficiency level to level 2 YX3-132 - m - 4 efficient motor,its

performance indicators such as table rotor and stator 1. According to the formula can be unit of electricity saving amount: 7.5 (1/0.87-1/0.901) 1 = 0.2966 kw? H,can calculate its investment cost recovery.Choose efficient motor,power saving effect is obvious,all update motor can be recouped in 1~2 years of investment. The service life of the equipment as the transformer and motor for decades,with high efficiency motor instead of high energy consumption,not only can improve the efficiency of energy conversion,and in terms of life power saving effect is significant,long-term development for the factory to provide big driving force.Close down backward production facilities application of highly efficient motor Backward in order to encourage inefficient motor exit the market,guide the existing motor enterprise gradually shift production efficient,state and local governments have taken some measures,and introduced the corresponding policies,encourage the development of high efficiency and energy saving motor.

Such as the ministry of finance,national development and reform commission jointly issued "about huimin projects to promote efficient motor energy saving products" detailed rules for the implementation of the notice,the level of energy efficiency for primary and secondary low-voltage three-phase asynchronous motor 15 to 40 yuan/kw subsidies; 12 yuan/kw subsidies for high-voltage three-phase asynchronous motor; Rare earth permanent magnet motor for 40 to 60 yuan/kw subsidies. Subsequently,the government,the economic and information commission of guangdong province issued "about the energy-efficiency subsidy issued by guangdong province motor detailed rules for the implementation of the notice,the detailed rules,points out that the modified motor conform to the 2012 edition of the new standard of energy efficiency and guarantee the value of the high voltage three-phase asynchronous motor efficiency,the northwest area of guangdong province subsidy standards for motor 140 RMB/kw power before modification,and the pearl river delta region (including shenzhen) province subsidy standards for motor 100 RMB/kw power before modification,and to encourage local according to the motor power before modification standard swallow the $200 per kilowatt. 

But the standard computing project subsidies amount shall not exceed 50% of its total investment,and obtain the motor system energy saving renovation subsidies enterprises,will not affect the application and other energy-saving enjoy national and provincial capital projects. However,have not reached,the government will impose punitive tariffs.Therefore,industrial enterprises should actively respond to national policy,the implementation of the application of highly efficient motor,backward inefficient motor,on the one hand,to reach the company's own saving energy and reducing consumption,reduce cost and performance of the corporate social responsibility; On the other hand,make full use of the government's subsidy policy,reduce the financial burden on enterprises.
