At present, China's small and medium-sized motors have about 300 series and 1,500 varieties. The products are widely used in various fields such as industry, agriculture, national defense, public facilities and household appliances. They are widely used to drive various blowers, pumps and compressors. Machines, machine tools, lifting and transportation machinery, urban transportation and industrial and mining electric vehicles, construction machinery, metallurgy, non-ferrous metals, textiles, printing, paper, petrochemical, rubber, food and other industrial equipment and agricultural machinery, with motor as the driving power source Its power consumption accounts for more than 60% of the country's total power generation.
China is in the process of deepening the reform of the economic system and the rapid development of the national economy. Enterprises are faced with the norms of macroeconomic regulation, energy and environmental protection policies. The regulations issued by the inspection agency have clarified the technical standards for energy-saving products, and the enterprises produce products through the standards of energy-saving technology products formulated by the government. At the same time, the government has implemented policy guidance for the energy-saving industry, strengthened law enforcement management, and established a good market environment for enterprises.
With the government's support for the energy-saving industry and the deepening of the concept of energy conservation, it is only a matter of time to build a healthy and orderly power-saving industry. At present, the motor industry has formed a relatively complete industrial system. The varieties, specifications, performance and output of small and medium-sized motor products basically meet the needs of the market.
Under the background of economic globalization, the world has entered an era of mutual competition and mutual trust, how to enhance the international competitiveness of Chinese enterprises, promote the establishment of energy-saving enterprises, strengthen industrial energy conservation management and technological transformation, and guide the development of energy-saving industries. Raising awareness of energy conservation, resource awareness and environmental awareness, giving full play to the advantages of Chinese enterprises, sustainable, rapid, coordinated and healthy development has become a problem that enterprises must face.
China's GDP accounts for 3.8% of the world, but it consumes 11% of global energy. This shows that China's economic operation is still a high-input, high-consumption, high-emission, uncoordinated, low-efficiency, difficult-to-cycle, extensive economic growth mode that has not yet been transformed into Low-input, high-output, low-consumption, low-emission, recyclable intensive and economical growth.
In recent years, China's sustainable economic development has been constrained by energy bottlenecks. In the second half of 2002, 11 provinces and cities nationwide lacked electricity. In 2004, power shortages expanded to 24 provinces and cities. Coal shortage, oil shortage. This also warns enterprises that there is still a lot of room for new product development, industrial technology, equipment efficiency and management level, and potential energy conservation should be tapped.
In view of the power shortage in China, energy-saving motors should be vigorously promoted. At present, the domestic motor production is large and the use is wide. Under the current severe energy and environmental problems, it is necessary to develop energy-saving motors or high-efficiency motors to further reduce the power consumed by the motors themselves, thus reducing the use of motor systems in China. Electricity.
The development of the motor industry should conform to the national strategic requirements—the motor industry should do the following in accordance with the requirements of national strategic development:
1. Develop new products for AC motors
The amount of AC motor accounts for more than 60% of the power generation. It is the "large power user" and the industry with the greatest energy saving potential. It seizes the opportunity of implementing the "motor energy-saving project" and actively carries out technical research on motor energy-saving projects and develops new products. Such as the development of ultra-high efficiency motors, high-efficiency permanent magnet synchronous motors, medium and high-voltage motor technology research and development, renewable energy supporting generator technology research and development, environmental indicators as a requirement to develop new products, vigorously reduce noise and improve industry technology .
2, do a good job of upgrading the motor
The state's industrial policy of "reducing heat with the heat" is a major policy for energy conservation and environmental protection. Y3 new series motor is the first complete series of cold-rolled silicon steel sheet in China. It is the basic series of magnetic conductive materials. It has reached the advanced level of the international similar products and is the upgrading product grade and quality level. On the basis of the Y3 series motor, we should pay close attention to the upgrade of other major derivative series motors, such as high-efficiency motors, low-noise and low-vibration motors, protective motors, variable-frequency motors, and electromagnetic brakes.
3. Actively develop motor and electrical integration products
Mechatronics technology is a comprehensive high-tech technology that combines various emerging technologies and precision machinery led by microelectronics. China's motor industry should increase investment in science and technology, and actively develop high-tech and high value-added mechatronics new products, such as inverter and motor combination as an integrated AC motor, which is widely used in fans, pumps, compressors, crushers, metallurgy, non-ferrous metals. , cement, textile food, industrial and mining vehicles and other equipment that require motor speed regulation, so that it can save energy in the transformation of China's motor products.
4. Improve the craft level of manufacturing companies
Advanced technology and equipment can improve the manufacturing level and product quality of the products. Enterprises should invest the necessary funds to transform the product process, tooling and equipment, and adopt advanced automatic detection technology in casting, stamping, gold processing, insulation treatment, etc. to ensure the quality of parts to meet new products and new standards. Request to promote the upgrading of industrial structure. Vigorously develop environmental protection industry, adjust product structure, strengthen technology development, especially product design, will gain a broad market, rely on scientific and technological progress and improve people's quality, and use existing information networks to provide market information to users in a timely and accurate manner.
Energy efficient motors will be one of the most important power equipment
Small and medium-sized motor companies will face high-efficiency and energy-saving motors as one of the most important power equipment, converting electrical energy into mechanical energy. Due to energy conservation and environmental protection considerations, many countries in the world, including China, have paid great attention to the energy saving of electric motor systems. The focus of electric energy saving on motors is more than 0.75KW.
