In the process of implementing the motor energy efficiency improvement plan, the cost of negotiation and transformation of individual projects is high and there are many obstacles. The establishment of the motor energy efficiency improvement industry alliance is conducive to the innovation operation mechanism, integrating motor production enterprises, contract energy management companies, energy conservation diagnostic institutions, and finance. Credit institutions and other units provide integrated system solutions for diagnosis, program design, financing, transformation, construction, and acceptance.
In order to complete and improve the energy efficiency of the generator and the energy saving of the motor system, eliminate the inefficient use of the motor and promote the high efficiency motor, the motor industry has specially established the motor energy efficiency industry alliance, and passed the "Electrical Energy Efficiency Improvement Industry Alliance Charter". It can be seen that China has taken the improvement of motor energy efficiency as the key work of industrial energy conservation, and the development of high-efficiency and energy-saving motor manufacturing industry in the future will be more robust and targeted.
Efficient energy-saving motor market gradually
At present, the electricity consumption of electric motors in the industrial sector accounts for about 75% of the total electricity consumption of the industry. Motor energy conservation has become the key to industrial energy conservation. With the dual pressures of energy saving, emission reduction and environmental protection, energy-saving equipment represented by high-efficiency motors has attracted much attention in the market.
A high-efficiency motor is a motor with a high efficiency of a general-purpose standard motor. High-efficiency motors use new motor designs, new processes and new materials to improve output efficiency by reducing losses in electromagnetic, thermal and mechanical energy. Compared with standard motors, the energy-saving effect of using high-efficiency motors is very obvious, and the efficiency can be increased by 4% on average.
In August last year, the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology announced that it would formally implement a motor energy efficiency improvement plan nationwide. The plan is to use three years to improve the energy efficiency of the national motor and promote the transformation and upgrading of the motor industry. More than 30,000 industrial enterprises with an annual electricity consumption of 10 million kWh or more will be the key targets of the plan.
According to industry analysts, it is estimated that the implementation of this plan will drive the demand for high-efficiency motors and related equipment to nearly 100 billion yuan. With the advancement of the energy efficiency improvement plan, the demand for high-efficiency motors will gradually be released, increasing year by year.
In addition, China's motor exports will also gradually increase
Nowadays, there are fewer and fewer enterprises engaged in the production of traditional electric motors in developed countries such as Europe and the United States, and Chinese motor companies may become their importers. The proportion of high-efficiency motors in domestic existing stock motors is less than 5%, and the high-efficiency motors produced are mainly sold abroad. At the same time, the proportion of high-efficiency motors in China is currently only 23% to 25%. An efficient energy-saving motor manufacturer told reporters.
Motor energy efficiency shortens and foreign gap
China has gradually become a major motor manufacturing country, mastering the production technology of high-efficiency and ultra-efficient energy-saving motors, but overall, the industry competitiveness is still weak. The amount of motor is large and the energy efficiency level is low.
At present, China's overall energy efficiency level is still far from that of foreign countries, especially the energy-efficient use of electrical equipment such as motors and transformers. The amount of electricity used is large and the application area is wide. The electricity consumed by the motor per year accounts for 64% of the total social power consumption. The energy consumption of the field motor accounts for more than 70% of the total electricity consumption in the industrial field. The energy efficiency of the motor system is much different from that of the foreign country, which is about 15%~20%.
In the future, on the one hand, we should carry out in-depth research on energy-saving technologies for motors and their systems, such as research and development of high-efficiency and energy-saving motors; high-efficiency fans, pumps, compressor systems; high-efficiency transmission systems; reasonable matching of motor systems; and system integration solutions for energy-saving of motor systems. On the other hand, it is necessary to formulate guidelines and standards for energy-saving of motor systems, such as guidelines for system energy-saving renovation, energy-saving testing and evaluation standards for motor systems in special fields. In addition, we must establish a motor system energy certification agency, such as market access certification, energy-saving product certification, energy-saving certification of various high-efficiency motor systems.
