The Development of Energy - Efficient Motor Assisted Manufacturing Industry
2016-10-12

Motor is an important industrial energy-consuming equipment, widely used in pumps, fans, compressors, transmission machinery and other fields, the power consumption accounts for about 60% of China's industrial electricity consumption, including small three-phase induction motor power consumption 35%, is a large power consumption, so the development of China's high-efficiency motor is one of the important measures to improve energy efficiency, in line with China's development needs is very necessary.
In the context of economic globalization, especially in the economic downturn, the pressure of industrial enterprises and the challenges encountered by the growing. Motor consumption, low energy efficiency, but also restricted the healthy development of the domestic economy. Therefore, the promotion of high-efficiency energy-saving motor has been urgent, not only is the industrial enterprises to meet the needs of social development, but also to keep domestic motor products to keep up with international development trend of the inevitable requirements, but also conducive to promoting industry technological progress and product exports.
Saving energy to reduce long-term operating costs
Motor is an important industrial energy-consuming equipment, widely used in pumps, fans, compressors, transmission machinery and other fields, the power consumption accounts for about 60% of China's industrial electricity consumption, including small three-phase induction motor power consumption 35%, is a large power consumption, so the development of China's high-efficiency motor is one of the important measures to improve energy efficiency, in line with China's development needs is very necessary.
The electrical energy saving project has been listed as one of China's key energy-saving projects, one of the key areas of national energy-saving emission reduction work. In the context of energy-saving emission reduction, the mandatory standards and incentives to determine the efficient energy-saving motor will replace the traditional low-efficiency motor, energy efficient motor is the use of new motor design, new technology and new materials, by reducing electromagnetic energy, thermal and mechanical energy Loss, improve the motor output efficiency of the motor.
Compared with the common standard motor, the use of energy efficient motor energy saving effect is very obvious, under normal circumstances, the average energy consumption decreased by 10%, efficiency can be increased by about 4%. Expert analysis, the motor throughout the life cycle, the purchase price accounted for 2% of the total cost of the motor, maintenance costs accounted for 0.7% of its total cost, while energy costs accounted for 97.3% .Therefore, from the motor's entire life cycle Consider, from the motor design, manufacture to the motor ion, operation, regulation, repair, retirement, energy efficient motors for the plant energy conservation, reduce life cycle operating costs, improve production efficiency and reduce environmental pollution, but also reduce energy Consumption and reduce carbon dioxide emissions, is conducive to plant sustainable development. In short, the effect of energy-saving sustainable throughout the machinery and equipment throughout the life cycle.
Investment cost recovery fast economic potential
Efficient energy-saving motor is very suitable for textiles, fans, pumps, compressors use, by about two years to recover energy-saving motor purchase costs. For example: a rated power of 7.5kw, energy efficiency rating of three Y2-132M-4 replaced with the same rated power, energy efficiency rating of two YX3-132M-4 high-performance motors, the performance indicators in Table 1. According to The formula can be obtained unit of electricity: 7.5 (1 / 0.87-1 / 0.901) 1 = 0.2966kw? H, can be calculated the cost of its investment recovery.
Select efficient motor, energy-saving effect is obvious, generally 1 to 2 years to recover all the investment in updating the motor. The use of high-efficiency motor instead of high-energy motor, not only can improve the energy conversion efficiency, but also in the life-saving effect is quite significant for the long-term development of the factory to provide a huge impetus.
Eliminate backward production capacity application of efficient motor
In order to promote the backward inefficient motor out of the market, and guide the gradual transformation of the existing production of motor efficient motor, national and local governments have taken some measures to develop and introduced a corresponding policy to encourage the development of efficient energy-saving motor.
Such as the Ministry of Finance, the National Development and Reform Commission jointly promulgated the "energy-saving products on the issuance of energy-efficient projects to promote efficient implementation of the motor to promote the implementation of the notice," the energy efficiency rating of one and two low-voltage three-phase induction motor given 15-40 yuan / ; High-voltage three-phase induction motor to give 12 yuan / kW subsidy; rare earth permanent magnet motor to give 40-60 yuan / kW subsidy. Subsequently, the Guangdong Provincial Government, Economic and Information Commission issued a "notice on the issuance of Guangdong Province, energy efficiency subsidies to enhance the implementation of the notice," the rules that the transformation of the motor in line with the 2012 motor energy efficiency standards or new high-voltage three-phase induction motor efficiency assurance The subsidy standard for the former is RMB140 / kW for the former motor power and RMB100 / kW for the former in the Pearl River Delta (excluding Shenzhen), and the local electric power is encouraged to be calculated according to the power of the motor before the transformation. Kilowatt 200 yuan of standard fill. However, the total amount of the above standard calculation project subsidies shall not exceed 50% of the total investment, and access to energy-saving motor system subsidies to enterprises, will not affect their application and enjoy the national and provincial energy-saving projects. However, for non-compliance enterprises, the government will impose punitive tariff.
To this end, industrial enterprises should actively respond to national policies, the implementation of efficient motor applications, eliminate backward inefficient motor, on the one hand to achieve their own energy saving, reduce costs and fulfill corporate social responsibility; the other hand make full use of government subsidies Policy, reduce the burden on enterprises.
