Working Principle of Servo Motors
A servo motor is a type of DC motor that uses a feedback mechanism to control its position, velocity, and acceleration. The working principle of a servo motor can be broken down into three main stages:
- The motor receives a signal from a controller, which instructs the motor to rotate to a specific angle or position.
- The motor’s shaft then moves to the desired position, and when it reaches the target angle, the motor’s position is verified by a feedback mechanism.
- The controller then adjusts the motor’s output to maintain the desired position, ensuring that the motor stays within a small margin of error.
This closed-loop feedback system allows servo motors to achieve high levels of accuracy, speed, and repeatability.
