In recent years, in order to improve the overall socio-economic and environmental benefits, energy conservation and emission reduction is the only way for industrial enterprises. With the transformation and upgrading of China's manufacturing industry, the energy efficiency of traditional motors has been gradually improved, and motor products have been constantly upgraded. The market prospect of energy-saving and the high - efficient motor is broad.
1. Motor plays an important role in industrial production
The motor is the mechanical equipment that realizes the energy conversion and transmission. As a mechanical power, it plays an important role in industrial production. At present, improving the energy-saving effect of the motor is a popular technology in the motor industry, and the energy-saving of the motor system mainly comes from the energy saving of motor products.
A three-phase cage induction motor has the advantages of low cost, easy control and strong reliability, and has gradually become an important research field to improve the efficiency of the motor. In addition, the development speed of the rare earth permanent magnet motor and switched reluctance motor is also accelerating.
2. China has a large market with a wide variety of motors
Motors have a wide range of applications, and different types of motors have different functions. Common motors include servo motors, stepper motors, torque motors, switched reluctance motors, brushless DC motors, DC motors, asynchronous motors, synchronous motors and so on.
The servo motor controls the whole system by converting the input voltage signal to the mechanical output on the motor shaft. This kind of motor is widely used in many control systems in various fields. Stepper motor is known as "the ideal executive component of CNC machine tools", mainly used in the manufacturing of CNC machine tools, plotters and printers. In addition, the asynchronous motor has the advantages of simple structure, easy operation, widely used in driving machine tools, mining machinery, medical equipment and other fields.
3. The growth rate of automobile manufacturers is slowing down, and the profit space is compressed
From the perspective of Chinese automobile manufacturers, the overall market size is large and the market growth rate is low. According to the National Bureau of Statistics, there were 2,854 large-scale automobile manufacturers in China in 2017, with a growth rate of just 0.18%. The growth rate of China's automakers has been slowing since 2012, and most domestic auto companies' profit margins have been squeezed.
In the context of energy conservation and emission reduction, the high-efficiency motor is in a better period of development. At present, rare earth permanent magnet coreless motor and cast copper rotor motor are one of the more promising and effective equipment. Outstanding enterprises in China's electrical industry include Mitsubishi Electric Group, Wolong Electric Motor Group Co., LTD., Panasonic Group, Siemens LTD., Dayang Electric Motor Co., LTD., Jiangxi Special Electric Motor Co., LTD., etc..
4. Development direction of energy-saving and high-efficiency motor in the future
The motor is a piece of important driving equipment for machine tools, compressors, transmission belts and other equipment. It is a high-power consumption machine. Overall, China's motor energy efficiency level is low, lower than the foreign average of 3%-5%. However, China's motor industry has disadvantages such as backward adjustment of the control system and unreasonable supporting facilities. The utilization rate of the high-efficiency motor is only 3%, resulting in the operation efficiency of China's motor system is 10%-20% lower than that of foreign advanced level.
In addition, a large number of inefficient electric motors cause a huge waste of electricity in China. Data show that for every 1% increase in motor efficiency in the manufacturing industry, 26 billion kilowatt-hours of electricity are saved annually. Therefore, the development of the energy-saving and efficient motor is one of the more potential energy-saving industries.
High efficiency and energy-saving, professional customization, intelligent automation, integration and integration are the important development direction of motor energy-saving technology in the future. From the point of view of energy conservation, various countries have gradually established energy conservation standards for the motor industry.
The International Electrotechnical Commission (IEC) has unified the global standards for motor testing and energy efficiency, and China has been constantly increasing the research and development of energy-saving projects for high-efficiency motors and motor systems.
Motor applications include metallurgical, petrochemical, municipal and other fields. The energy efficiency of the downstream industry is constantly improved, which promotes the development of professional motor products according to their own characteristics. In addition, with the development of China's equipment manufacturing industry and the gradual realization of the integration of industrialization and information technology, intelligent motor system has become an important development trend.
With the application of electronic information technology in the manufacturing industry, the motor is no longer a part of the realization， but can realize the complete function of the electromechanical integration system. On the basis of exploring motor system integration, major Chinese enterprises continue to explore and launch more mature products.
