A programmable logic controller (PLC) or microcontroller sends a target position signal to the servo drive.
Processes the input signal and feedback to adjust the motor's position. Slide 4: Working Principle Closed-Loop Feedback:
A servo motor is not just a simple motor; it's a highly efficient, self-contained electrical device that rotates or pushes a part of a machine with great precision. In a servo system, the motor's output (position, velocity, or acceleration) is constantly monitored and compared to the desired command. Any error is corrected, making it a , which differs from a standard open-loop system that lacks this feedback and correction mechanism. The term "servo" originates from the Greek word for "slave," reflecting the motor's role in faithfully following the commands from a control system. servo motor ppt presentation download
: Explain the Closed-Loop System . Use a diagram showing the motor, sensor (encoder), and control circuit. Key Components : DC Motor : The power source. Gear System : To reduce speed and increase torque. Control Circuit : The "brain" that processes signals. Potentiometer/Sensor : Provides position feedback. Types of Servo Motors : AC Servo Motors : High power, used in industrial machinery.
Older brushed DC models require brush replacements. Slide 9: Real-World Applications Robotics: Joint movements in robotic arms. In a servo system, the motor's output (position,
is a precise actuator—either rotary or linear—designed for the exact control of angular or linear position, velocity, and acceleration. Unlike standard motors that rotate continuously when powered, a servo operates within a closed-loop system
