Multi-turn electric actuators are an essential component in modern industrial systems, particularly in applications that require precise and reliable rotational motion. These actuators convert electrical energy into mechanical motion to rotate equipment, such as valves, dampers, and gates, through multiple turns. The distinct feature of multi-turn actuators is their ability to perform more than a single rotation, which is necessary for processes where precise control of large or heavy machinery is required. In this article, we will explore the functionality, advantages, and applications of multi-turn electric actuators.
