发电机励磁系统定义

发电机由两大部分组成。

（1） 转子 —— 转子绕组通以直流，用以产生发电机的磁场；

（2）定子—— 定子绕组被磁场之磁力线切割，在定子绕组中产生（发出）电流。对于交流发电机，发电机转子被原动机（水轮机、汽轮机、柴油机等）拖动转动，因而转子绕组产生的磁场是旋转的，静止的定子绕组相对运动切割磁力线。

UNS4881b,V4 excitation is a device that provides stator power to the stator of a generator or synchronous motor.

UNS4881b,V4 according to the different excitation mode of DC motor, can be divided into separate excitation, parallel excitation, series excitation, complex excitation and other modes, DC motor rotation process, excitation is to control the stator voltage to generate its magnetic field

Change, change the speed of the DC motor, change the excitation also plays a role in changing the speed.

Excitation is the device that provides stator power to the stator of a generator or synchronous motor.

According to the different excitation mode of DC motor, it can be divided into separate excitation, and excitation, series excitation, complex excitation, etc., during the rotation process of DC motor, excitation is to control the voltage of the stator so that the magnetic field generated by it changes, changing the speed of the DC motor, changing the excitation also plays the role of changing the speed.

Generator excitation system definition

The generator consists of two parts.

(1) Rotor - rotor winding through DC, to generate the generator's magnetic field;

(2) Stator - The stator winding is cut by the magnetic line of the magnetic field, and the current is generated (emitted) in the stator winding. For the alternator, the generator rotor is dragged by the prime mover (water turbine, steam turbine, diesel engine, etc.), so the magnetic field generated by the rotor winding is rotating, and the static stator winding relative motion cuts the magnetic field line.
