永磁励磁系统是电励磁系统的另一个主要分类。它使用永磁材料(磁铁、强磁体等)，在外界电磁效应的作用下，产生自发的磁场，从而促进电机的性能改善。与电励磁系统相比，永磁励磁系统的优点在于:受外界干扰的抗力相对来说更强，而且维护成本较低。

同时，永磁励磁系统不需要额外的电源或电压，只需要励磁磁铁即可完成励磁，普遍受到设计工程师的欢迎。

励磁系统可以改善机械和电机的性能和工作效率，又能够降低故障风险，保护电机运行的稳定性。励磁系统的分类有电励磁系统和永磁励磁系统，它们既有各自的优缺点，也有各自的特点。

电励磁系统的特点是性能优化方便、经济易行;而永磁励磁系统则以其受外界干扰程度低，维护方便而著称，有着更高的实用性。

Permanent magnet excitation system is another main classification of electrical excitation system. It uses permanent magnet materials (magnets, strong magnets, etc.) to generate a spontaneous magnetic field under the action of external electromagnetic effects, thereby promoting the performance of the motor. Compared with the electric excitation system, the advantages of the permanent magnet excitation system are: the resistance to external interference is relatively stronger, and the maintenance cost is lower.

At the same time, the permanent magnet excitation system does not require additional power or voltage, and only needs an exciting magnet to complete the excitation, which is generally welcomed by design engineers.

Excitation system can improve the mechanical and motor performance and work efficiency, but also can reduce the risk of failure, protect the stability of motor operation. The classification of excitation system has electrical excitation system and permanent magnet excitation system, they have their own advantages and disadvantages, but also have their own characteristics.

The characteristic of the electric excitation system is that the performance optimization is convenient and economical. The permanent magnet excitation system is known for its low degree of external interference, easy maintenance, and higher practicability.
