Permanent magnet traction technology--China's breakthrough in the field of magnetic materials

Permanent magnet traction technology--China's breakthrough in the field of magnetic materials

Permanent magnets, which can maintain continuous magnetism for a long time, such as the application of more artificial permanent magnets (mainly NdFeB), which are made of some metals and new materials after systematic processing, they can have long-term magnetism, around the magnets. In the presence of a magnetic field, the iron will be magnetized, and the magnetized iron block and the magnet can have the effect of attracting opposites, and the iron block is firmly adhered to the magnet.

Characteristics analysis of rare earth permanent magnet materials sintered NdFeB and SmCo

Permanent magnet motors are widely used, but how many people know the categories of permanent magnet materials? What are the characteristics and advantages and disadvantages of different permanent magnet materials? Which models should be selected under different environments and applications? This article is based on such a starting point, to do some characteristic analysis of permanent magnet materials, especially "NdFeB and Samarium Cobalt" rare earth permanent magnets.

What problems should a novice pay attention to when purchasing tile-shaped magnets (magnetic tiles)?

What problems should a novice pay attention to when purchasing tile-shaped magnets (magnetic tiles)?

There are two main types of tile-shaped magnets, namely NdFeB magnetic tiles and ferrite magnetic tiles. At present, these two are mostly used, mainly used in some DC motors.

The purpose of the motor magnetic tile

It is mainly used in permanent magnet DC motors. Unlike electromagnetic motors, which generate magnetomotive force sources through excitation coils, permanent magnet motors use permanent magnet materials to generate constant magnetomotive force sources.
