technical field

The invention relates to the technical field of permanent magnet synchronous motors, in particular to a permanent magnet synchronous motor with a protection structure.

Background technique

In order to realize the conversion of energy, a synchronous generator needs a DC magnetic field, and the DC current that generates this magnetic field is called the excitation current of the generator. According to the supply method of excitation current, any generator that obtains excitation current from other power sources is called a separately excited generator, and if it obtains excitation power from the generator itself, it is called a self-excited generator. The automatic adjustment excitation system can be regarded as a In the negative feedback control system with voltage as the adjusted quantity, the reactive load current is the main reason for the voltage drop of the generator terminal. When the excitation current remains unchanged, the terminal voltage of the generator will decrease with the increase of the reactive current. However, in order to meet the user's requirements for power quality, the terminal voltage of the generator should remain basically unchanged. The way to achieve this requirement is to adjust the excitation current of the generator with the change of the reactive current.
