How Many Methods of Magnets Fixing in New Energy Drive Motors?
How are magnets fixed inside the rotor core of a permanent magnet motor? This is one of the most important questions in modern drive motor design. Since most drive motors today are permanent magnet synchronous motors (PMSM), magnets fixing methods directly affect motor performance, safety, and reliability. A small number of drive motors still use asynchronous motors, but they do not involve magnets at all.
