At the same time, with rapid economic development, energy demand will grow rapidly.Explosion proofMotorA type of motor that can be used in flammable and explosive plants, and it does not generate sparks during operation.Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.However, in the process of energy utilization, unnecessary energy loss is inevitable. However, in the current energy situation, we have always emphasized energy efficiency. In the case of unavoidable loss, improving energy utilization efficiency will become a direction for the automotive industry. Comprehensive development and solution.
Motor market development trend
my country’s economic exchanges and market price competition for electric motors are becoming increasingly fierce. Private small and medium-sized enterprises and foreign-funded management companies need to have the strength of competitive companies with strong capabilities to occupy a larger share of the world market.The new round of the 30th Five-Year Plan will also bring new developments to the industrial structure of AC motor technology that achieves high efficiency and energy saving.The statistical results show that an industry in my country's cultural exchange motor design and manufacturing industry has not undergone more than 10 years of continuous reform, innovation and opening up, especially in the past 20 years, it has achieved world-renowned achievements. In the 80s, the output of AC motors in Chinese society has been hovering around 4000 million kilowatts. From 1988 to 1997, the cumulative output was about 4 million kilowatts. In 2009, the output of AC motors was 18710.17 million kilowatts. In 2010, the output of my country's information AC motors was up to 23212.91 kilowatts, a year-on-year increase of 24.07%.
At the national level, the policy of China's small and medium-sized motor industry is mainly to promote energy-efficient motors.Compared with ordinary motors, energy-efficient motors have reduced losses by an average of 20% and improved efficiency by 2%-7%; IE4 efficiency motors have an average of 2% more energy than the effective motor efficiency.The energy saving of the motor system has a huge impact on the implementation of the national policy of the energy saving and emission reduction strategy. .
In 2012, the global economic and efficient development of energy-saving motors was mainly researched in other regions in Asia and Europe, which accounted for 60.8% of the world's total output.The production areas in Asia are mainly concentrated in China, Japan, South Korea and India, and the main problems affecting European production are concentrated in countries such as Germany, the United Kingdom, and France. From 2007 to 2012, the proportion of the output of high-efficiency and energy-saving motors in the Americas and some parts of Europe gradually began to decline. The production structure of global resource-efficient and energy-saving motor companies has shown the characteristics of shifting from developed countries to developing countries.
In order to meet the development requirements of the national economy, my country vigorously promotes high-efficiency energy-saving motors.High-efficiency and energy-saving motors refer to general-purpose standard motors with high efficiency.The high-efficiency and energy-saving motor adopts new motor design, new technology, new materials, and improves output efficiency by reducing electromagnetic energy, thermal energy, and mechanical energy loss.Compared with standard motors, the energy-saving effect of using high-efficiency motors is very obvious, usually the efficiency can be increased by 4 on average.
High-efficiency and energy-saving motors will become the new darling of national policies and the market, and their development prospects are promising.At the same time, in accordance with the requirements of the Tenth Five-Year Plan for the automobile industry, my country will adjust its industrial structure in the future, optimize the industrial technology structure and organizational structure, accelerate the elimination of backward technologies and processes, and improve the overall competitiveness of the industry.
