1、直流电机是指将直流电送到直流电机，把直流电机的电能转换成机械能。这里首先要介绍如何将市电的交流电转换成需要的直流电。

六十年代以前采用的是发电机--电机系统(F-D)，这种方法只有在电机由专用的发电机供电时才有可能。

2、另—种是可控硅--电机系统(SCR-D)。
两种系统的原理如下:

执行机构的阀位维持在一定的开度上，一定的信号压力就对应于一定的阀位开度。以上作用方式为正作用，若要改变作用方式，只要将凸轮翻转，A向变成B向等，即可。所谓正作用器，就是信号压力增加，输出压力亦增加:所谓反作用器，就是信号压力增加，输出压力则减少。一台正作用执行机构只要装上反作用器，就能实现反作用执行机构的动作;相反，一台反作用执行机构只要装上反作用器。

1, DC motor refers to the direct current to the DC motor, the DC motor electrical energy into mechanical energy. Here we first introduce how to convert the alternating current of the mains into the required direct current.

Before the 1960s, the generator-motor system (F-D) was used, which was only possible when the motor was powered by a dedicated generator.

2, the other is thyristor - motor system (SCR-D).
The two systems work as follows:
emerson 5X00121G01 Controller Emerson Pressure into the actuator film chamber increases, causing the stem to move downward. And drive the feedback rod to rotate around the fulcrum, the feedback CAM also rotates counterclockwise, the auxiliary lever 4 rotates around the fulcrum through the roller, and the feedback spring is stretched, the spring on the main lever 3 tension and signal pressure used on the bellows force to achieve torque balance, the instrument reaches a balanced state.

SAMSON 3731-3 Electropneumatic declaration form
The valve position of the actuator is maintained at a certain opening, and a certain signal pressure corresponds to a certain opening of the valve position. The above mode of action is positive, if you want to change the mode of action, just turn the CAM, A direction into B direction, etc., you can. The so-called positive actor is that the signal pressure increases and the output pressure also increases: the so-called reaction actor is that the signal pressure increases and the output pressure decreases. As long as a positive acting actuator is installed with a reaction actuator, the action of the reaction actuator can be realized. In contrast, a reaction actuator only needs to be equipped with a reaction device.
