New motor will bring new breakthroughs in the electric vehicle industry

Few people know that the motor is not compelling, but consumes more than half of the country's electricity. High efficiency motor is one of the most effective way to save electricity, the promotion of high efficiency motor has become a major event in China's economic transformation, energy conservation and emission reduction and haze governance.

According to statistics, in 2015, China's motor capacity of about 2 billion 400 million kilowatts, the total power consumption of about 3 trillion and 500 billion kwh, accounting for the total electricity consumption of the whole society by 65%.

Through the promotion of energy efficiency, can improve the overall efficiency of China's motor system from 5 to 8 percentage points, can achieve annual saving of between 130 billion and 230 billion kwh, equivalent to the annual electricity output of 2 to Three Gorges power station.

In fact, the motor is not far away from our life and production, to drive the fan, water pump, compressor and other equipment, small to common household washing machine, electric fan, air conditioning, motor is widely used in industry, agriculture, transportation, municipal, household appliances and other fields, which require electricity can be transformed into mechanical energy or mechanical energy into electrical energy of the place must be used for motor.

Because of the wide range of applications, the motor has become the largest power consumption terminal equipment. According to estimates, in 2015, China's motor fleet of about 2 billion 400 million kilowatts, the total power consumption of about 3 trillion and 500 billion kwh, accounting for 65% of the total electricity consumption of the whole society in which the motor industry total power consumption of 2 trillion and 900 billion kwh, accounting for 74% of the electricity industry, industrial motor consumption accounted for 52% of the total electricity use of the whole society.

In recent years, with the support of national policy, the level of energy efficiency of motor in China has been gradually improved, but the overall level of energy efficiency is still low. From the motor itself, China's motor efficiency average of 3 to 5 percentage points lower than the foreign countries, currently in use of high-efficiency motors accounted for only about 8% from the motor system, because the matching is not reasonable, regulation of backwardness and other reasons, the operating efficiency of the motor system than the low level of foreign advanced 10 to 20 percentage points, a large number of the use of inefficient motor caused a huge waste of electricity. In the field of industrial electrical energy efficiency increased by 1 percentage points per year can save electricity about 26 billion kwh.

The energy saving of motor system is an important part of building a conservation oriented society and developing circular economy in china. At present, there are two types of high efficiency motors in the market: YE3 series super high efficiency three-phase asynchronous motor He Yong magnetic synchronous motor. But according to the market parties reflect the real effect of energy-saving YE3 motor is not good, and the permanent magnet motor has the advantages of energy saving, stable occurrence of different degrees of degaussing reluctance motor in use after a period of time, but the technology is difficult to achieve.

It is worth noting that the technology will help solve the existing electric car dilemma. Zhou Qingyu said that at present, the science and Technology Development Co. Ltd. if motor technology used to improve the existing electric vehicle motor, motor energy saving rate 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 characteristics of the motor without current shock, battery life will increase by 100%, to reach 20 years.

Experts said that on the one hand, the switched reluctance motor system is an ideal equipment for technological transformation of enterprises and the upgrading of products, used in industry can reduce energy consumption by more than 20%, but also reduce the emissions of industrial waste, promote the transformation and upgrading of enterprises. On the other hand, motor, electric control, power supply is three key electric car companies, new motor as a breakthrough, to solve the pure electric vehicle mileage is short of the problem, promote the further development of China's electric vehicle industry.
