The new motor will bring new breakthroughs for the electric vehicle industry

Motor is not far away from our production, life is not far away, large fan, water pump and other equipment drive device, small to the family commonly used washing machines, electric fans, air conditioning, motor widely used in industry, agriculture, transportation, municipal, home appliances And other fields.

According to statistics, in 2015, China's motor ownership of about 2.4 billion kilowatts, the total power consumption of about 3.5 trillion kwh, accounting for 65% of the total electricity consumption.

Through the improvement of energy efficiency, the overall efficiency of China's motor system to upgrade 5 to 8 percentage points, can achieve annual savings of 130 billion to 230 billion kwh, equivalent to two to three Three Gorges power plant annual power generation.

Few people know that not the attention of the motor, but consumed more than half of the country's electricity. Efficient motor is one of the most effective way to save electricity, promote efficient motor has become China's economic restructuring, energy saving and even haze governance of a major event.

"Electricity significantly reduced." This is the Guangdong Ceramics Co., Ltd. after the use of energy efficient motor after the obvious changes. "Ceramics are high energy-consuming industries, electricity costs in the total cost of a higher share." The company official said, the company will be efficient motor for ceramic ball mill, the energy-saving rate of 18%, according to industrial average 0.8 yuan / kWh measured, the annual cost savings of 64,624 yuan, more than 1 year will be able to recover the cost of investment transformation.

In fact, the motor from our production and life is not far away, large fans, pumps, compressors and other equipment drive device, small to the family commonly used washing machines, fans, air conditioning, motor widely used in industry, agriculture, Traffic, municipal, home appliances and other fields, all need to be converted into mechanical energy or mechanical energy into electrical energy must be used to the motor.

Because of the wide range of applications, the motor has become the largest power consumption of the terminal equipment. It is estimated that in 2015, China's motor ownership of about 2.4 billion kilowatts, the total power consumption of about 3.5 trillion kwh, accounting for 65% of the total electricity consumption of the whole society; of which the total industrial power consumption of 2.9 trillion kilowatts , Accounting for 74% of industrial electricity, industrial motor power consumption accounted for 52% of the total electricity consumption.

In recent years, with the support of national policy, China's motor energy efficiency level gradually increased, but the overall level of energy efficiency is still low. From the motor itself, the average level of motor efficiency in China is 3 to 5 percentage points lower than that of foreign countries. At present, only about 8% of the high-efficiency motor is used. From the motor system, because of the unreasonable match and the way of adjustment, the motor system Operating efficiency than the advanced level of foreign low 10 to 20 percentage points, the use of inefficient motor caused a huge waste of electricity. Industrial energy efficiency for each increase of 1 percentage point, can save about 26 billion kwh of electricity.

Harbin Institute of Technology Vice President Xu Dianguo said that through the improvement of energy efficiency, can improve the overall efficiency of China's motor system 5 to 8 percentage points, can achieve annual savings of 130 billion to 230 billion kwh, the equivalent of two to three Three Gorges Power Station Of the annual electricity generation.

The energy saving of the motor system is an important part of the establishment of a conservation-oriented society and the development of circular economy. Its core lies in technological breakthrough. At present, the market has an absolute advantage in the efficient motor has two categories: YE3 series of ultra-efficient three-phase asynchronous motor and permanent magnet synchronous motor. However, according to the parties to the market, YE3 motor actual energy-saving effect is not good, and permanent magnet motor in the use of a period of time will occur in varying degrees of demagnetization; reluctance motor has a stable, energy-saving advantages, but the technology is more difficult.

Reporters in the market research found that Shenzhen Wind Technology Development Co., Ltd. through nearly 10 years of research and development, not only broke through the switching magnetoresistive motor motor technology problems, and has been successful in this technology to achieve industrialization. This year in October, this technology has been identified by the Ministry of Industry and Technology achievements, the energy efficiency can reach 15% to 20%, far more than the existing efficient motor technology.

At present, the enterprise switched reluctance motor has been in ceramic, chemical and other industries put into use. Fengfa Technology Development Co., Ltd. Chairman Zhou Qingyu told the "Economic Daily" reporter, Shandong Laiwu Taihe Biochemical Co., Ltd. will be equipped with three-phase asynchronous motor into a smart speed motor, the energy-saving rate reached 20.16%. Foshan City, Sword Co., Ltd. on the ball mill energy-saving comparison test shows that energy-saving rate also reached 14% to 16%.

It is worth noting that the technology will help solve the existing electric vehicle dilemma. Zhou Qingyu revealed that the current Wind Technology Development Co., Ltd. motor technology if used to improve the existing electric car motor, motor energy efficiency can be as high as 50%. This also means that in the case of the same battery capacity, electric vehicle mileage can be increased by 50%; coupled with the motor no current impact characteristics, battery life will increase 100% to 20 years.

Experts said that on the one hand, switched reluctance speed motor system is the enterprise technological transformation and product upgrading of the ideal equipment used in industry can reduce energy consumption by more than 20%, but also reduce the industrial waste emissions, promote enterprise transformation and upgrading The On the other hand, the motor, electronic control, power supply is the three key electric vehicle business, new motor can be a breakthrough, to solve the current pure electric vehicle mileage short problem, to promote China's electric vehicle industry to further develop.
