The characteristics of permanent magnet generators: Using rare earth permanent magnetic materials (such as neodymium iron boron), no excitation current is required. The structure is simpler. By adjusting the three-phase current, the stator magnetic field and the rotor magnetic field rotate synchronously, with an efficiency of up to 92%-96%. They are suitable for scenarios such as wind power generation and high-speed power generation in aviation, and are particularly suitable for fields with high efficiency requirements.
