Bioelectric motor

At present, there are about 100 million industrial motors, 25 million compressors, and 30 million fans and pumps in China. Compared with developed countries, the average efficiency is 3 to 5 percentage points lower, and the operating efficiency is 10 to 20 percentage points lower. The annual electricity consumption of the motor has exceeded 2 trillion kWh. Technological progress and policy incentives have made the level of motor energy efficiency in developed countries higher and higher, and the gap between China and the country is growing. At present, 21.8% of the motors used in China are J series motors in the 1960s and 1980s, and 74% are Y series motors in the 80s and 90s. In the past two years, due to the development of the national Huimin project, the total number of low-voltage high-efficiency motors and high-voltage high-efficiency motors such as YX3 has reached more than 10 million kilowatts, but it accounts for only a small proportion compared with the national storage motor of 1.7 billion kilowatts.

Inefficient motors have a 50% energy saving potential. However, there are only 30 to 50 companies with the ability to design, produce and test high-efficiency motors. Some industrial motor system users lack understanding of the economic benefits brought by energy saving of the motor system, or have obstacles to understanding the technical problems of energy-saving transformation of the motor system, and lack of effective information platform to share the successful experience in energy-saving transformation of the motor system. Xu Shaoshan, Director of the Business Development Department of China Quality Certification Center, said: "The large use of inefficient motors has caused huge waste of electricity. For every one percentage point increase in energy efficiency in the industrial sector, it can save about 26 billion kWh of electricity per year."

China has become a major motor manufacturing country, mastering the production technology of high-efficiency and ultra-efficient energy-saving motors, but overall, the industry competitiveness is still weak. The large amount of motor and low energy efficiency limit the healthy development of China's national economy. In the use of the motor, there is also a phenomenon of “big horse-drawn car”, and the promotion and application of high-efficiency motors are urgently needed.

"High-efficiency motor energy consumption is 20%~30% lower than that of ordinary motors. However, China's high-efficiency motors now have a market share of only 10%. Under the situation that the energy-saving and emission-reduction situation is getting more and more severe, it is of great significance to promote high-efficiency motors. Zhao Yuejin said.

Although the country has announced the elimination period, the implementation of the elimination period is determined by the local or industry authorities, and most local or industry departments have not specified the elimination date of the outdated equipment, and supervised the use of the eliminated equipment. Management is not based on regulations, resulting in the elimination of the J series and JO series motors in use is not ideal.
