Industrial Servo Drive
Place of Origin
In the previous figure, the controlled system is a movable table for which the position or speed is controlled. The movable table is driven by a ball screw and is connected to the servomotor via gears. So, the drive system consists of:
Gears + Ball Screw
This drive system is most commonly used because the power transmission ratio (gear ratio) can be freely set to ensure high positioning accuracy. However, play in the gears must be minimized.
The following drive system is also possible when the controlled system is a movable table:
Coupling + Ball Screw
When the power transmission ratio is 1 : 1, a coupling is useful because it has no play. This drive system is widely used for machining tools. Timing Belt + Trapezoidal Screw Thread A timing belt is a coupling device that allows the power transmission ratio to be set freely and that has no play.
A trapezoidal screw thread does not provide excellent positioning accuracy, so can be treated as a minor coupling device.
To develop an excellent servo system, it is important to select a rigid drive system that has no play.
Configure the controlled system by using an appropriate drive system for the control purpose.
Also called a drive mechanism.
A drive system connects an actuator (such as a servomotor) to a controlled system and serves as a mechanical control component that transmits torque to the controlled system, orientates the controlled system, and converts motion from rotation to linear motion and vice versa.
