Servo Motor

Servo motor is a type of motor that works with a specific signal or command. These motors produce high performance results in applications where precise positioning and speed control are required. For this reason, they are frequently preferred in many areas.

Servo motor works with a sensor and control mechanism. Full position and speed determination is possible in this way. The motor controller calculates the movement required to achieve the correct position by adjusting the speed and torque of the motor. Servo motors are used in conjunction with drive systems. These drives are used to control the operation of these motors.

What does a servo motor do? These motors are frequently preferred in systems with complex movements and precise positioning requirements. Therefore, they are widely used especially in robotics, automation and industrial controls. The three basic components in these motors can be listed as follows;

Motor: DC or AC servo motor types are available.
Sensor (Encoder): Used to determine the position of the motor.
Control Circuit: It is the control system that ensures the correct position.

Working Principle of Servo Motors

These motors follow a specific signal until they reach the desired position. This signal usually comes from a control device such as a microcontroller or PLC (Programmable Logic Controller). The controller uses the feedback from the encoder to determine if the motor has reached the desired position. If the motor is not in the desired position, the controller adjusts the motor until it is in the correct position.

These motors have many advantages for the user. Some of them can be listed as follows;

High precision
High torque
Speed control
Dynamic braking.

However, these motors can be more costly and have complex systems. Despite the possibility of these situations, these motors are preferred for many studies due to the advantages they bring.

Servo Motor Driver

Servo motor drives are the drives that allow the correct operation and control of these motors. The movement, speed, position and torque of the motor can be controlled with the help of these drives. For this, it usually receives control signals from a PLC, microcontroller, etc. and is realized by comparing the real-time position and speed of the motor with encoder feedback.

What are motor drives? The use of servo motors is realized in combination with drive systems. Servo type motor drive is used to control the operation of these motors. These drives adjust motor speed and torque using data from a feedback position sensor. Motor drives provide precise positioning, speed and torque control.
