DC servo motors are a type of electric motor that provides precise control of angular position, velocity, and acceleration. They operate using direct current (DC) and are commonly used in applications requiring accurate movement, such as robotics and automation systems. These motors typically consist of a rotor, stator, and feedback mechanism, which allows for real-time adjustments. The feedback system helps maintain the desired position by comparing the actual position to the target position, making DC servo motors ideal for tasks that require high precision and reliability.
