Realistic distress, high-efficiency energy-saving motor applications urgently need policy support
Recently, the National Development and Reform Commission issued an announcement to accelerate the promotion and promotion of energy-saving technologies, and to guide energy-using units to adopt advanced and applicable new energy-saving technologies, new equipment and new technologies to promote energy-saving and intensive use of energy resources, and alleviate resource and environmental pressures. National Key Energy-saving and Low-carbon Technology Promotion Catalogue (2015, Energy-Saving Part), involving 266 key energy-saving technologies in 13 industries. The rare earth permanent disk type ironless core motor technology was selected as the key energy-saving technology.
In this regard, industry experts believe that the development and production of ultra-efficient motors is an important basis for improving the efficiency of motor systems, which will help promote the improvement of motor energy efficiency in China.
Promote energy efficient motor applications
At the "Rare Earth Permanent Magnet Forum" recently attended by reporters, experts and scholars called for "the state continues to strengthen the policy support for rare earth high-efficiency permanent magnet energy-saving motors and promote the widespread application of rare earth high-efficiency permanent magnet energy-saving motors."
"Rare earth permanent magnet motor has the characteristics of small size, light weight, simple structure, energy saving and high efficiency. It can be widely used in general equipment such as fans, pumps and compressors. It can also be used in electric vehicles, wind power generation, CNC machine tools, oil field pumping units, Mobile power stations and other fields.” Academician Gu Guojun of the Institute of Electrical Engineering of the Chinese Academy of Sciences pointed out that the current large-scale permanent magnet wind turbine technology has matured, and it is expected that there will be a substantial combination of production, learning, research and use. Participants called on the state to continue to strengthen the policy support for rare earth high-efficiency permanent magnet energy-saving motors and promote the widespread application of rare earth high-efficiency permanent magnet energy-saving motors.
In terms of wind power generation, rare earth permanent magnet wind turbines have light weight and high power generation efficiency, which can reduce wind farm cost and wind power cost. The market demand for rare earth permanent magnet wind turbines is huge.
"In recent years, the state has increased the promotion of high-efficiency motors, and many policies have been introduced, including financial subsidies, but the effect is not obvious. At present, the proportion of high-efficiency motors in the national memory is only about 8%." Chinese private manufacturing enterprises 500 Strong enterprise, chairman of Jiangxi Taihao Group Co., Ltd. Huang Daifang believes that in recent years, the state has increased the promotion of high-efficiency motors, and has formulated motor energy efficiency rating standards in accordance with IEC standards. Many policies have also been introduced to support the application and promotion of high-efficiency motors. However, the share of high-efficiency motors is growing slowly.
Huang Daifang believes that China is currently facing some problems in the promotion of high-efficiency motors. For example, currently inefficient storage motors are mainly distributed in high-energy steel, cement, metallurgy, paper and other enterprises. In addition, the proportion of medium and large-sized motors in inefficient storage motors is relatively high. The efficiency values of medium and large-sized motors are tested by motor manufacturers. The use of enterprises cannot determine whether the efficiency of motors truly meets the high-efficiency motor standards, resulting in the selection and use of some enterprises. When the motor is used, there are certain concerns about the energy saving benefits in the later stage.
