Servomotorok

Servomotorok, often shortened to servos, are a type of electric motor that allows for precise control of angular or linear position, velocity, and acceleration. Unlike standard electric motors that rotate continuously when powered, servomotors have a built-in feedback mechanism. This feedback system, typically a potentiometer or encoder, reports the motor's current position to a controller. The controller then compares this actual position with the desired position and adjusts the motor's power accordingly to reach and maintain the target.

The core components of a typical servomotor system include the motor itself, a feedback sensor, and a control circuit. The motor is often a DC or AC motor, but its design is modified to be compatible with the feedback system. The control circuit receives a command signal, usually a pulse-width modulated (PWM) signal, which dictates the desired position. It then processes the feedback from the sensor and drives the motor to minimize the error between the desired and actual positions.

Servomotors are widely used in applications requiring accurate movement and positioning. This includes robotics, where they are essential for controlling the joints of robotic arms, remote-controlled vehicles, and automated manufacturing equipment. They are also found in cameras for autofocus and zoom mechanisms, in the aerospace industry for controlling control surfaces, and in various consumer electronics. Their ability to hold a specific position even under load makes them invaluable in many electromechanical systems.
