A servo motor can be rightly described as a rotary actuator or a linear actuator which allows precise control on the angular and linear position, the velocity as well as the acceleration. It usually consists of a proper motor which is coupled with a sensor for providing position feedback. It sometimes also requires a relative top-notch controller which is majorly a dedicated module which is specifically designed for efficient use with the servo motors.
As per the Ac Servo Motor Supplier, the servo motors do not fall under the class of generalised motor. The name servo motor is used for referring to a motor type which is used in a completely closed looping control system. These motors are used in several applications including projects of robotics, the CNC machinery and find special usage.
Mechanism of Servo Motors
A servo motor follows a closed-loop servo mechanism which uses a fixed position of feedback for controlling the motion and the final position of the machine in which it is used. The input of the control is directly linked with a signal, which is either analogue or digital, depending entirely on the position which is commanded for the output shaft.
The AC servo motor is usually paired with a few types of encoders which helps in providing a position along with speed-related feedback. In most cases, only the position angle is measured. The position of the output is generally compared with the command position or through the external input of the controller.
If the position of the output differs from the required, the signal gets automatically generated, which makes the motor to rotate in either of the two directions for bringing the output shaft to an appropriate position. When the position approaches, the error signal gets reduced to zero, and the motor automatically gets stopped.
Are Servo Motors AC or DC?
There is a vast difference between an AC servo motor and a DC servo motor. The prime aspect is to how electricity works. AC servo motors are advantageous over DC as this type of electrical current changes voltage of power easily. A transformer helps in doing this.
Usage of Servo Motors
The servo motors which make use of a simple operating process make use of only the ‘position only' sensing ability through a potentiometer or a bang-bang controller. Such motors either rotate at full speed or stay completely in the stop position. However, these types of servo motors are not widely used in the field of industrial motion control. Some of the simple servo motors are used for serving various radio-based requirements.
The servo motors designed meeting the requirements of modern technology are sold by several AC servo motor supplier in your city. You can also go in for an online platform to get hold of the quality motor suiting to your needs. These motors have a dedicated controller module which is sometimes developed based on the microcontroller.
Why Use Servo Motors?
It helps in cutting down the cost for the large volume-based applications. Apart from that, you can even get hold of integrated servomotors which are specially designed in which you can easily add up the motor, drivers, encoder, and all the required electronics catering to your needs.
