High-speed new energy vehicles have been in a state of high-speed operation. The speed of its permanent magnet synchronous motor can even reach 12,000 rpm, which requires the high-temperature adaptability of the vehicle motor. It is the optimization of rare earth permanent magnet materials that makes the motor have good heat resistance. The same high-performance rare earth materials also provide the necessary conditions for permanent magnet traction systems to be applied to high-speed rail. Permanent magnets that can withstand high and low temperatures are also the top priority. Read More
The magnets we know are divided into permanent magnets and non-permanent magnets. The permanent magnet itself can also be a natural product, or it can be manufactured artificially.
Magnets have a very peculiar function. It can attract materials such as iron and nickel. It plays a very important role in industrial society. The earliest words people use are dug out from nature, but the magnetism of that kind of magnet is very weak and the magnetism is not stable enough. On the basis of this time, a magnet was made by groping step by step. Do you know how magnets are made? Read More
