Servo Motors

Definition: A servo motor is a closed-loop control system that precisely controls angular or linear position, velocity, and acceleration.

Key Components:

• DC/AC Motor
• Gear System
• Potentiometer (for position feedback)
• Control Circuit

Working Principle: Receives PWM signal; pulse width determines shaft position (e.g., 1.5ms = center).

Voltage: Typically 4.8V to 6V.

Common Types:

• Positional Rotation (0° to 180°)
• Continuous Rotation
• Linear Servo

Applications: Robotics, RC vehicles, automation, camera focus systems.

Note: Always check torque, speed, and operating voltage before integration.
