The PM motor uses permanent magnets to generate the motor's magnetic field. It does not require an excitation coil or excitation current.
Compared with the traditional electric excitation motor, it has significant advantages such as high efficiency and simple structure.
The application range of permanent magnet motors is extremely wide, covering almost all areas of aerospace, national defense, industrial and agricultural production and daily life.
With the development of high-performance permanent magnet materials and the rapid development of control technology, the application of permanent magnet motors will become more extensive.
