Energy-saving motor

- Jan 20, 2019-

According to the "China High-tech Industry Herald" report: The General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China promulgated the national mandatory standard GB18613-2002 "Energy efficiency limit value and energy-saving evaluation value of small and medium-sized three-phase asynchronous motor" on January 1 this year, in 2002 It was implemented in August, and the China Energy Conservation Product Certification Center also launched the certification work. Based on this, a series of seminars on energy efficiency national standard and energy-saving product certification for small and medium-sized three-phase asynchronous motors were held recently by the Department of Resource Conservation and Comprehensive Utilization of the State Economic and Trade Commission, the China Standards Research Center and the China Energy Conservation Product Certification Center. The energy efficiency standards, test methods and energy-saving certification procedures of electric motors in China and abroad are introduced.

Director Xu Zhiqiang of the Energy and New Energy Department of the Resources Department of the State Economic and Trade Commission said: China's use of energy is still far behind that of developed countries. In particular, many enterprises consume a lot of energy. For example, the main product units of some enterprises can The consumption is even more than 40% of foreign countries, and the energy saving space is still very large. The electricity consumed by electric motors in China accounts for about 60% of the national electricity consumption, while small and medium-sized electric motors account for 75% of the national motor power. If the efficiency of small and medium-sized motors is increased by one percentage point on average, more than 2 billion kw/h can be saved in one year. . The export volume of small and medium-sized motors is about 7 million kw per year, accounting for 20% of the total output of AC motors. It is one of the important export electromechanical products in China. With the accession to the WTO, international trade is strengthened, and foreign motor energy efficiency standards are used as a non-trade. Sex barriers will exert certain pressure on China's motor product exports.

Director Chen Yunhua of the National Certification Body Accreditation Committee said that standards are the fundamental basis for production and directly affect the quality and competitiveness of products. GB18613-2002 "Energy efficiency limit value and energy conservation evaluation value of small and medium-sized three-phase asynchronous motor" is the energy efficiency standard of the first industrial equipment in China. It is not only the technical basis for motor production, but also the implementation of China's energy policy in the field of motor production and application. The main basis is that it is equivalent to the EU agreement indicators in terms of technical indicators, and the test method adopts the advanced method of the United States.

It is reported that the Resources Department of the Economic and Trade Commission has listed the formulation and revision of energy efficiency standards for major industrial energy-consuming equipment as one of the key tasks. The energy efficiency standards for small and medium-sized motors are the first energy efficiency standards for industrial products formulated by China, and will be organized in the future. Energy efficiency standards for industrial products such as compressors, fans and pumps.
