The increasing downward pressure on the economy makes it urgent to promote efficient and energy-saving motors

In the environment of increasing downward pressure on the economy, industrial enterprises are facing increasing pressure and challenges. The large amount of motors and low energy efficiency also constrain the healthy development of the domestic economy. Therefore, promoting high-efficiency and energy-saving motors is urgent. This is not only a requirement for industrial enterprises to adapt to social development, but also a necessary requirement for domestic motor products to keep up with international development trends. At the same time, it is also conducive to promoting industry technological progress and product exports.

The increasing downward pressure on the economy makes it urgent to promote efficient and energy-saving motors

The transformation and upgrading of industry has brought enormous development space to the motor industry. It is expected that by 2020, the installed capacity of electric motors in China will reach 2.5 billion KW, and an additional 800 million KW of total installed capacity will be added in the next five years.

According to statistical calculations, in 2015, the total number of electric motors in China was about 2.4 billion kilowatts, with a total electricity consumption of about 3.5 trillion kilowatt hours. The total electricity consumption of the whole society was 5.55 trillion kilowatt hours, accounting for 65% of the total electricity consumption of the whole society; Among them, the total power consumption of industrial motors is 2.9 trillion kilowatt hours, and the industrial power consumption is 3.93 trillion kilowatt hours, accounting for 74% of the industrial power consumption. The power consumption of industrial motors accounts for 52% of the total electricity consumption of the whole society.

In the environment of increasing downward pressure on the economy, industrial enterprises are facing increasing pressure and challenges. The large amount of motors and low energy efficiency also constrain the healthy development of the domestic economy. Therefore, promoting high-efficiency and energy-saving motors is urgent. This is not only a requirement for industrial enterprises to adapt to social development, but also a necessary requirement for domestic motor products to keep up with international development trends. At the same time, it is also conducive to promoting industry technological progress and product exports.

Electric motors are widely used in the industrial field as driving devices for various mechanical equipment such as fans, pumps, compressors, machine tools, and transmission belts. Their electricity consumption accounts for more than 60% of China's total industrial electricity consumption, of which small three-phase asynchronous motors consume about 35%, making them a major power consumer. Therefore, developing high-efficiency electric motors in China is one of the important measures to improve energy utilization efficiency, which meets the needs of China's development and is very necessary.

The energy-saving engineering of motor systems is a key area of national energy conservation and emission reduction work. In the context of energy conservation and emission reduction, mandatory standards and incentive policies determine that high-efficiency and energy-saving motors will fully replace traditional and inefficient motors in the future. High efficiency and energy-saving motors adopt new motor designs, new processes, and new materials to improve the output efficiency of motors by reducing the loss of electromagnetic energy, thermal energy, and mechanical energy.

Efficient and energy-saving products that are green, environmentally friendly, and low-carbon are the trend. Based on a total installed capacity of 2.5 billion KW, if the energy efficiency value of all motors is increased by 5 percentage points, it can reduce the construction of many power stations and greatly reduce the overall social carbon emissions, "said Ye Jinwu, Chairman of Zhejiang Jinlong Electric Motor Co., Ltd." Currently, our annual production and sales are 700-80 million yuan, of which the proportion of ultra high efficiency motors is increasing. In 2015, the proportion increased by 30% compared to 2014, and now it accounts for more than 70% of the overall sales

Compared with ordinary standard motors, the energy-saving effect of using high-efficiency energy-saving motors is very significant. Generally, the energy consumption is reduced by an average of about 10%, and the efficiency can be improved by about 4%. According to expert analysis, throughout the entire lifecycle of the motor, its purchase price accounts for 2% of the total cost of the motor, maintenance costs account for 0.7% of its total cost, and energy consumption costs account for 97.3% Therefore, considering the entire lifecycle of electric motors, from design and manufacturing to selection, operation, regulation, maintenance, and disposal, high-efficiency and energy-saving motors can save energy consumption, reduce lifecycle operating costs, improve production efficiency, and reduce environmental pollution for factories. They can also reduce energy consumption and carbon dioxide emissions, which is beneficial for the sustainable development of factories. In short, the energy-saving effect can be sustained throughout the entire lifecycle of mechanical equipment.

According to statistics, for every one percentage point increase in the energy efficiency of industrial motors, approximately 26 billion kilowatt hours of electricity can be saved annually. By improving energy efficiency, the overall efficiency of the motor system can be increased by 5-8 percentage points. Annual energy savings of 130-230 billion kilowatt hours can be achieved, equivalent to the power generation of 2-3 Three Gorges power stations.

The promotion of efficient motors can be traced back to 2007. In 2008, China listed the energy-saving of motor systems as one of the top ten energy-saving projects in the country. In 2009, the application of high-efficiency and ultra high efficiency motors was included in the welfare project for the people. On June 2, 2010, a notice was issued stating that high-efficiency motors would be included in the scope of energy-saving product welfare projects, which has attracted much attention to the market promotion of high-efficiency motors.

Efficient and energy-saving motors are very suitable for use in textiles, fans, water pumps, and compressors. By saving electricity for about two years, the purchase cost of the motor can be recovered. Choosing an efficient motor can significantly save electricity, and the investment in updating the motor can generally be recovered within 1-2 years. And motor equipment, like transformers, has a service life of several decades. Replacing high energy consuming motors with high-efficiency motors can not only improve energy conversion efficiency, but also have significant energy-saving effects in terms of lifespan, providing a huge driving force for the long-term development of factories.
