China Motor Industry Future Technology Development New Trend

efficiency

At present, the total installed capacity of electric motors in our country has reached more than 0.4 billion KW, with annual power consumption reaching 1.2 trillion KWh, accounting for 60% of the country's total power consumption and 80% of industrial power consumption. Among them, the total installed capacity of fans, pumps and compressors has exceeded 0.2 billion KW, with annual power consumption reaching 800 billion KWh, accounting for about 40% of the country's total power consumption. Based on the current market situation, it is estimated that every one percentage point increase in motor efficiency in the country can save more than 26 billion kilowatts of electricity per year. If the efficiency of the motor system is increased by 5%-8%, the electricity saved per year is equivalent to the power generation of two to three Three Gorges reservoirs. Enough to see the huge potential and importance of the motor energy-saving market, so the efficiency of the motor will always become the development trend of motor technology.

the country to increase the promotion of high-efficiency motors, with reference to IEC standards to develop motor energy efficiency rating standards, but also issued a number of policies to support the application and promotion of high-efficiency motors, but the share of high-efficiency motors growth is slow. At present, China is still facing some problems in the promotion of high-efficiency motors. For example, the current low-efficiency stock motor is mainly distributed in high energy-consuming steel, cement, metallurgy, paper and other enterprises.

high reliability

reliability has always been an important consideration for the user to choose a motor. The longer life of the motor and the more compact structure are the embodiment of high reliability. The life of the motor has a great relationship with the temperature rise. Improving the efficiency of the motor and reducing the temperature rise can effectively extend the service life of the motor.

intelligent

Mechatronics and intellectualization With the development of science and technology, the technology of mechatronics has been developed by leaps and bounds. At the same time, various high and new technologies have also injected new vitality into motor products. The manufacturing process and management information technology have gradually shortened the development cycle of new products through the application of microelectronics, computer and network technology, the encouragement of national policies and the attention of enterprises to science and technology, electromechanical integration, intelligent motor (such as AC variable frequency speed regulation motor is a stepless speed regulation transmission system) came into being, speed control manufacturing, virtual manufacturing and other advanced manufacturing technology to promote the application. The technical performance level of our country's motor is equivalent to that of developed countries.

lightweight, miniaturization
The lightweight and miniaturization of the motor can effectively save materials and space, and is more and more favored by users. Many products also put forward high requirements for the volume and weight of the motor, which is more obvious in the fields of petroleum, chemical, coal and other applications. In order to achieve the goal of light, miniaturization, in the design process, the use of advanced technology and high-quality materials, and adhere to the principle of optimization design, in the effective material unchanged conditions, the weight of the unit power continues to reduce, is the future development trend.

the excellent motor enterprises in China, they have been committed to the research of realizing the lightweight and miniaturization of motors. For example, Nanyang explosion-proof, Hebei motor and other well-known domestic motor enterprises have made many attempts to realize the miniaturization of motors, and have studied and developed the solutions of copper rotor motors.

In order to make full use of the characteristics of copper and give full play to the research and development advantages of cast copper rotor motors, the existing frame number motors are optimized and designed to reduce one or two frame numbers to ensure electrical performance while achieving volume reduction and weight reduction., The purpose of cost reduction.
