As an important device for electromechanical energy conversion, the motor is the basic component of electric transmission. It not only has a wide range of applications, a large variety of products, and a variety of specifications, but also has many manufacturers and sub-sectors involved.

Looking at the development in recent years, China seems to have made great progress in the field of motor manufacturing, and some companies have mastered the production technology of high-efficiency and ultra-efficient energy-saving motors. However, from the perspective of domestically produced motor products, most of them are ordinary motors with low efficiency and energy consumption, with relatively low grades and low technical content. What cannot be ignored is that with the increasing competition in the market, leading motor manufacturers in the industry pay more and more attention to the research of the industry market, especially the more in-depth research on changes in customer demand trends.

In an environment where production costs remain high and energy consumption is reduced globally, high-efficiency and energy-saving motors will become an inevitable trend in the development of the motor industry worldwide. In addition, the motor industry, as a leading industry for energy conservation and environmental protection, new energy, new energy vehicles, and high-end equipment manufacturing, coupled with the support and guidance of current policies, represents the promotion of energy conservation and environmental protection of high-efficiency motors will continue to increase.

According to relevant industry analysis, there are currently many types of motor products in China, but the efficiency is not high. There is still a large gap between the promotion of high-efficiency motors and the global level. 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. Therefore, the future road of the motor industry will gradually develop in the direction of high-efficiency, energy-saving and intelligent motors under the promotion of policies and markets.

Therefore, motor drive and motor control are still two important "wheels" in the development of the motor industry, and they have been an important focus of many domestic engineers. In line with the principle and purpose of sharing and communication of motor drive and control technology, Big Bit Information prepared two online live seminars for this purpose on May 29, and exchanged the latest technology and products for both motor drive and motor control. .
