The world's first permanent magnet motor comes out, after 30 years of research will eventually show rare earth advantages

The permanent magnet motor is a technology and equipment successfully developed by Germany in the 1980s. Since the world’s first permanent magnet motor developed in Germany, China has started related research work. After 30 years of unremitting efforts, we finally see the dawn of victory.

On October 23, the official WeChat platform of China Shipbuilding Industry Corporation issued the news “China's first permanent-vehicle permanent magnet propulsion electric locomotive was successful, with complete independent intellectual property rights,” claiming that China’s first permanent magnet motor with completely independent intellectual property rights was recently in Sanya. Successful loading of the test boat. This also marks that China successfully broke the Western monopoly and entered the world's top echelon in this field.

According to published data, this new type of motor is mainly benefited from rare earth materials in China. It replaces the excitation principle of traditional DC motors with high-performance permanent magnets. It not only has a large power, a low noise, but also has stable performance, can work continuously, and belongs to the power of ships. The important step of leap-forward development. According to reliable sources, China's permanent magnet motor test targets meet the requirements, and many of the indicators have reached the world's advanced level.

This permanent magnet motor is a brand new product with complete intellectual property rights in China. It immediately puts China into the first camp. Li Jie, a naval expert, said that the domestically-produced permanent magnet propulsion motor will break the international monopoly and will play an important role in the development of China’s naval vessels, especially submarines. It is one of the performances of our country’s marine electric 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 in the past. Now it has entered the stage of running and has already ranked among the world's first arrays. After the successful test of the permanent-magnet propulsion motor installed on the actual boat, it will take a long time for the permanent magnet motor to be put into practical use.

According to the official website of the 712 Institute, the institute has a national permanent magnet motor laboratory, which can carry out research and testing of motors and units with capacity below 3500KW and permanent magnet motors. After the completion of the laboratory, it has filled domestic high-power permanent magnet motors. Studying the test blanks, its permanent magnet motor testing capability is the first in Asia.

The advanced performance of permanent magnet motors has attracted the research public relations of major countries in the world. In 2010, Russia announced that the “Amur” class conventional power submarines use 4100 kilowatt permanent magnet motors. Britain, France, and the United States have all used permanent magnet motors.

Seeing the technological progress made by China, China has realized that China's equipment technology has entered a new era such as the United States, Britain, France, and other countries. It stated that in the next step in the development of medium voltage high power permanent magnet motors, cooperation with China could be considered.
