Excitation system can be divided into the following five categories according to the motor performance and excitation circuit parts parameters:

1. DC excitation system: This excitation system uses DC motor or hand wheel excitation generator excitation, mainly used in high-voltage large-capacity motors, stepper motors and Marine generators, etc., with good stability, small size, easy control, low power consumption and high reliability characteristics.

2. Bad excitation system: The excitation system uses the excitation DC current extracted from the motor stator to excite, and the excitation current can be adjusted for the ratio of the motor, which can avoid the overload phenomenon due to the high ratio of the motor, and improve the ratio characteristics and stability of the motor.

3. Speed control excitation system: speed control excitation system changes the speed of the motor through the change of excitation current, it uses a constant excitation current to adjust the speed of the motor, can adjust the speed of the motor to the required speed as far as possible, can greatly improve the speed control effect of the motor.

4 synchronous excitation system: synchronous excitation system is a technology designed for the synchronous motor of the power plant to adjust the encoder input pulse and control the output excitation voltage and current. The speed of synchronous motor can be accurately controlled by the excitation current, so as to improve the speed regulation accuracy of the motor.

5. Three-phase excitation system: three-phase excitation system is composed of DC power supply and three-phase excitation transformer input, its main role is to stabilize the operating state of the motor. For example, the use of excitation current can reduce the load of the motor, improve the anti-voltage fluctuation and load capacity of the motor, effectively improve the stability of the motor, reduce the loss, thereby improving the efficiency and power factor of the motor.
