Servo Drives: What You Need To Know

Servo drives are designed to offer among other things, exact control,

optimum torque as well as a rich set of features to complement the linear

positioning systems and rotary servomotors. When choosing these drives it pays to go with those that

provide high connectivity with advanced control technologies. The ideal drive should also be easy to

commission and it should have a very compact packaging as well.

Servo drives can be used by a machine to offer excellent quality motion control in a very dynamic application. The best drives are those that are paired with a range of servomotors and which at the same time can be run with virtually every different kind of servomotor.

It should have software that is flexible and it should also come with the following:

The ideal servo drive is also one that is able to offer support for AC induction motors as well as DC motors. You should also be able to use these drives for dynamic motion applications in which you need to enjoy exact positioning and proper speed control as well as torque efficiency. When choosing these drives you should have plenty of options including three hundred watts to fifty thousand watts of non-stop duty power output.

Servo drives are a motor control device that is capable of outputting electrical signals to servomotors in order to encourage motion. There are different types of servo drives including those that are built into the motor as well as those which are standalone devices.

The main function of the servo drive is to obtain command signals from control systems. These signals will then be amplified and then transmitted as electric current to servomotors in order to produce motion which is proportional to that of the command signal. In most cases the command signals are a certain velocity but it may also represent a certain amount of torque or even a desired position. Sensors will be connected to the servo motors and these will then report the real status of the motor to the servo drive.

Servo drives will then make a comparison of the real status of the motor with the command motor status. If there is a deviation from the command status the same will then be altered by the servo drive.
