The green industry begins with the “power consumption big crocodile” motor “slimming”
China is a big energy consumer, and industrial energy consumption accounts for more than 70% of the total energy consumption of the whole society. The motor system is a veritable “power consumer” in industrial energy consumption, and more than 70% of the electricity is used to drive its operation. Therefore, in the industrial green transformation and development, the “energy-consuming crocodile” – the energy-saving transformation of the motor system has received much attention.
Motor system energy consumption accounts for 70% of industrial energy consumption
"Motor is an electromagnetic mechanical device that utilizes the interaction of electricity and magnetism to achieve energy conversion and transmission. Motor systems are widely used in high energy-consuming industries such as steel, chemicals, cement, building materials, paper, solar energy and new materials." Switzerland TOP10 Zheng Tan of the Energy Conservation Center gave a brief introduction to the motor.
In his view, “the motor must be used wherever electrical energy needs to be converted into mechanical energy or converted into electrical energy. Therefore, the motor industry as a whole has a huge market capacity.”
In China, the motor industry has gone through a hundred years of history. According to statistics, at present, the number of small and medium-sized motors in China is 1.6 billion kilowatts. China has become the largest producer, exporter and exporter of small and medium-sized motors.
At the same time, the energy consumption caused by the motor can not be underestimated.
“Our national GDP accounts for 12% of the world's GDP, but energy consumption accounts for 22% of the world's total. The energy consumption per unit of high-energy-consuming industries is as high as 10%. The operating efficiency of motor systems and motors and dragging equipment is advanced with foreign advanced technology. The difference is 20%.” At the “China Manufacturing 2025: High-end Equipment Manufacturing and Industrial Application Collaborative Innovation Summit Forum” held recently, Wang Hao, director of the Development and Consulting Department of China Electrical Equipment Industry Association, said, “The motor is a transit device. Energy consumption is exhausted by the motor, which will bring a major blow to industrial energy conservation."
As one of the first batch of 11 low-carbon pilot cities in China and one of the first 11 pilot cities for industrial green transformation and development approved by the Ministry of Industry and Information Technology, Zhenjiang paid more attention to the energy-saving transformation of the motor system. Especially at the first Sino-US Climate Leaders Summit in September, Zhenjiang proposed to achieve the goal of peak carbon emissions by around 2020.
To this end, the Zhenjiang Economic and Information Committee held the World Wide Fund for Nature and signed the "Strategic Cooperation Framework Agreement on Industrial Green Transformation and Development Projects". The two sides will strengthen cooperation in energy efficiency technology, capacity building, investment and financing, and jointly promote the industrial green of Zhenjiang City. Transformation and development. In the first phase of their cooperation project, they aimed at the "large electricity users" - industrial motor systems.
