Considering the use of motor controls in the industrial sector for various needs can be essential for the industries. Especially when servo motor (มอเตอร์ เซอร์ โว, which is the term in Thai) is being considered, they offer great assistance making the industrial work a lot simpler.
These motors are essentially a part of a closed-loop system and it consists of several parts essentially the control circuit, potentiometer, drive gears, amplifiers as well as a resolver or an encoder. Thus, it is necessary to have a good idea of what a servo motor works before going into depths about it.
What is A Servo Motor?
To understand the basics of the motor, it can be stated that the servo motor is essentially an electrical device that is self-controlled and it is responsible for rotating parts of a machine with the highest efficiency and definite precision.
It is possible to move the shaft of the motor to a definite angle, position as well as a defined velocity that cannot be done with a regular motor. This is possible because, in this motor system, a regular motor is used which is in turn coupled with a sensor that helps in receiving possible feedback.
How Does A Servo Motor Function?
Concerning the other components of the motor, the controller is the most important part of it which is designed and utilized specifically for this purpose. The motor works in a closed-loop mechanism that involves the possible feedbacks received from the sensor and uses it to control the linear or rotational speed as well as the position of the machine. The controlling of the motor is done with the help of electric signals which can be both digitals as well as analog.
These electrical signals define the amount of movement which in turn characterizes the final command spot for the shaft. For the function of sensors, a type of encoder helps provide speed, position as well as feedback of the shaft.
The circuitry of the system is set up right inside the motor which is usually fitted along with the gear system. Thus, the total operation of the system can be read precisely with the help of the feedback reports.
What Are The Different Classifications of Servo Motors?
Essentially there are only two classifications of the servo motor which are dependent upon how they are being applied and their current type namely, DC servo motor and AC servo motor. While on the other hand, communication used that is if the motor uses any brush or what type of motion is exhibited by the rotor that is, asynchronous or synchronous; these factors also define the type of the motor. Thus, depending entirely on the type of operation as exhibited by the motors, the type of it is defined.
