What is Synchronization and Why Would You Need It?
What is synchronization? The concept is in the name: motion control devices being actuated in a ‘synchronized’ manner, and running at the exact same speed. The linear motion of multiple actuators are matched with each other to achieve complete synchronization. On the surface, synchronization can seem like an easy task. However, it can be entirely the opposite. Synchronization isn’t just achieved by wiring multiple actuators to the same switch, as many might presume – in an ideal world or a very simple setting, this might work. However, usually, it will result in multiple linear actuators moving at different speeds. Even if two linear actuators of the same make and model are connected to the same power supply, a significant speed difference can occur if both are subjected to unequal loads, have experienced different wear and tear patterns, or are at different operating temperatures even, to mention a few problems.
To achieve synchronized linear actuator movement, some form of motion control is a must. For an open-loop control system, the most popular synchronization option is a speed controller. A more sophisticated form of synchronized motion control is with a closed-loop system, which utilizes feedback from actuators to ascertain the individual needs of each device, making real-time adjustments. This form of synchronization is remarkably accurate, with no chance of error. There are multiple applications where linear actuator synchronization is a core requirement.
