1. A DC motor refers to delivering direct current to the DC motor, converting the electrical energy of the DC motor into mechanical energy.

Here, it is first necessary to explain how to convert the alternating current from 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. Another method is the silicon-controlled rectifier-motor system (SCR-D).

The principles of the two systems are as follows:

Emerson 5X00121G01 Controller Emerson allows increased pressure to enter the actuator diaphragm chamber, causing the valve stem to move downward. This drives the feedback lever to pivot around the fulcrum, and the feedback cam also rotates counterclockwise. Through the roller, the secondary lever 4 pivots around the fulcrum, stretching the feedback spring. When the spring's pull on the main lever 3 balances the force applied by the signal pressure on the bellows, the instrument reaches a balanced state.

The actuator's valve position is maintained at a certain opening degree, meaning a specific signal pressure corresponds to a specific valve opening degree. The above action mode is direct-acting. To change the action mode, simply flip the cam, turning direction A into direction B, etc. A direct-acting actuator means that as the signal pressure increases, the output pressure also increases; a reverse-acting actuator means that as the signal pressure increases, the output pressure decreases. A direct-acting actuator can achieve reverse action by installing a reverse-acting device; conversely, a reverse-acting actuator can achieve direct action by installing a reverse-acting device.
