The energy saving of the motor system is an important part of China's establishment of a conservation-oriented society and the development of a circular economy. Its core lies in technological breakthroughs. At present, there are two types of high-efficiency motors that have an absolute advantage in the market: YE3 series ultra-high efficiency three-phase asynchronous motors and permanent magnet synchronous motors. However, according to the market participants, the actual energy saving effect of the YE3 motor is not good, and the permanent magnet motor will have different degrees of degaussing after using for a period of time; the reluctance motor has the advantages of stability and energy saving, but the technical implementation is difficult.
In the market research, the reporter found that Shenzhen Fengfa Technology Development Co., Ltd. has not only broken through the technical problems of switched reluctance motor, but also successfully industrialized this technology. In October of this year, this technology has passed the scientific and technological achievements of the Ministry of Industry and Information Technology, and its energy-saving effect can reach 15% to 20%, far exceeding the existing high-efficiency motor technology.
At present, the company's switched reluctance motor has been put into use in ceramics, chemical industry and other industries. Zhou Qingyu, Chairman of Fengfa Technology Development Co., Ltd. told the Economic Daily reporter that Shandong Laiwu Taihe Biochemical Co., Ltd. converted the original three-phase asynchronous motor into an intelligent speed-regulating motor, and the power saving rate reached 20.16%. Foshan Liangjian Co., Ltd. conducted a comparison test on energy saving of the ball mill, showing that the power saving rate also reached 14% to 16%.
It is worth noting that this technology will help solve the existing electric car dilemma. Zhou Qingyu revealed that the current motor technology of Fengfa Technology Development Co., Ltd. can be used to improve the existing electric vehicle motor, and the motor energy saving rate can be as high as 50%. This also means that the electric vehicle's cruising range can be increased by 50% under the same battery capacity; coupled with the motor's no-current impact, the battery life will increase by 100% to 20 years.
Experts said that on the one hand, the switched reluctance motor system is an ideal equipment for technological transformation and product upgrading. It can reduce energy consumption by more than 20% in industry, and also reduce industrial waste emissions and promote enterprise transformation and upgrading. . On the other hand, the motor, electric control and power supply are the three key points of the electric vehicle enterprise. The new electric motor can be used as a breakthrough to solve the problem that the current pure electric vehicle has a short cruising range and promote the further development of the electric vehicle industry in China.
