• Exciter • Automatic Voltage Regulator Essentially the process of generating voltage goes in the following order. The exciter provides DC current to the rotor windings. DC current through these wires creates magnetic flux. Magnetic flux generates an AC voltage in the nearby stator windings when there is relative motion between the two.
A circular vibrating screen operates using a motor to drive an eccentric shaft, which creates a circular motion of the screen. This motion causes the materials on the screen to move in a circular path, facilitating the separation of particles based on size. Here is a step-by-step explanation of how a circular vibrating screen works.
