The world's first permanent magnet motor is available. After 30 years of research, it will show the advantages of rare earth.
The permanent magnet motor is a technical equipment developed by Germany in the 1980s. Since the world's first permanent magnet motor was developed in Germany, China began relevant research work. After 30 years of unremitting efforts, we have finally seen the dawn of victory.
On October 23, CSIC’s official WeChat platform released the news that “China’s first permanent magnet propulsion electric motor vehicle has been successfully completed and has completely independent intellectual property rights”, claiming that China’s first permanent magnet motor with completely independent intellectual property rights has recently been in Sanya. The loading test was successful. This also marks that China has successfully broken the Western monopoly into the world's first echelon in this field.
According to the public information, this new type of motor mainly benefits from China's rare earth materials. It replaces the excitation principle of traditional DC motors with high-performance permanent magnet materials. It not only has high power, low noise, but also stable performance and can work continuously. It belongs to ship power. An important part of leaping development. According to reliable sources, all the indicators of permanent magnet motor test in China are in line with the requirements, and many indicators have reached the world advanced level.
This permanent magnet motor is a brand-new product with completely independent intellectual property rights in China, and it will let China enter the first camp at once. Navy expert Li Jie said that the domestic permanent magnet propulsion motor broke the international monopoly and will play an important role in the development of China's warships, especially submarines. It is one of the performances of China's marine motors in the world's first array. The role of permanent magnet motors in submarines will be obvious. In the field of marine motors, China used to run, and now enters and runs, has become the world's first array. After the successful test of the permanent magnet propulsion motor installed in the actual boat, it will not take much time, and the permanent magnet motor will be put into practical use.
According to the official website of the 721, the institute has a national permanent magnet motor test room, which can carry out research and test of motor and unit and permanent magnet motor of 3500KW capacity. After the test room is built, it fills the domestic high-power permanent magnet motor. In the blank of the research test, the test capability of the permanent magnet motor is the first in Asia.
The advanced performance of permanent magnet motors has attracted research public relations in major countries around the world. In 2010, Russia announced that the "Amur" class conventional submarine used 4100 kW permanent magnet motors. Permanent magnet motors have been used in the United Kingdom, France, and the United States.
Seeing the technological progress made by China, we have realized that China's equipment technology has entered a new era. The United States, Britain, France and other countries have indicated that they can consider cooperation with China in the next step of developing medium-voltage high-power permanent magnet motors.
