Motors, transmissions and generators excited by permanent magnet materials work based on Faraday's law and Lorentz force. The magnetic properties of permanent magnet materials are remanence, coercivity, magnetic energy prod…
When a certain kind of magnet is used to provide energy to the other party, the magnet forms a "HMS" (High Mode Magnetic Generator). There are two common ways to construct these generators, one is to use iron blocks in the core, a…
Toyota Motor Corporation developed the world's first neodymium reduction heat-resistant magnet. Neodymium (Nd) magnets are used in various types of motors, such as high-output motors used in electric vehicles. This new type of mag…
Rare earth minerals mainly exist in the form of minerals in the earth's crust, and there are two main types of occurrence states: as the basic constituent elements of minerals, rare earths are present in the mineral lattice in the…
There are many ways to magnetize magnets. We all know this, but in the magnetizing methods of motor magnets, the common ones are mainly parallel magnetization, radial inner magnetization, and radial outer magnetization. There are …
Sintered NdFeB permanent magnets are magnetic materials with the highest magnetic properties found so far, and are widely used in various fields such as wind power generation, new energy vehicles, maglev trains, and intelligent ro…
