Synchronous control of electric linear acutator


Actuator Synchronization

News and Articles


An electric linear actuator can be an ideal solution for an application across various different industries. However, what if the application requires two or more actuators to move a load when one won’t suffice? In this case, the actuators must be designed to have a synchronous movement.


Actuator synchronization is important to keep the actuators moving at the same speed to maintain precise control and equal load distribution. If there is unequal load distribution, you run the risk of introducing moment loads that can be detrimental to both the actuator and application.


Synchronous control will output variable voltage to each actuator using feedback devices, typically in the form of Hall sensors or potentiometers.


Hall sensors output a square wave pulse signal that can allow a user to determine both how fast and the direction a motor is spinning. A control can then be used to compare pulse outputs/counts between multiple actuators to keep actuator speed and position in the alignment.


A potentiometer provides an analog signal output in the form of voltage/resistance which can be compared by a controller across all connected actuators to determine stroke.

When either of these two methods is used to ensure actuator synchronization, your application should function smoothly and efficiently, reducing the risk of actuator failure from unequal load distribution and torque.
