The goal of this project is to intro All motors have three wires coming out of them. Servo motors have three terminals - power, ground, and signal. A servo is a special type of motor that is designed to rotate to a particular position and hold that position until told to rotate to a different position. It is a different story when the motor is powered, even a small torque motor when powered and positioned in a degree (say 90*) then we will not be able to rotate it because the motor is constantly trying to keep the motor in that position 90* so when you rotate the motor by hand it will push it back to the previous position, Also it is not recommended to rotate the motors by hand because it will damage the gears inside. If you want to rotate an object at some specific angles or distance, then you use a servo motor. At this condition, there will be no output signal from the amplifier to the motor input as there is no difference between external applied signal and the signal generated at potentiometer, and in this situation motor stops rotating. The servo drive is a kind of controller to control the servo system. In them they ensure that your machines and equipment run trouble-free at the high quality level you have come to … So the main task of servomechanism is to maintain the output of a system at the desired value at presence of noises. Now motor shaft is connected with the potentiometer and as the motor rotates so the potentiometer and it will generate a signal.
