Electromagnetic actuators are devices that convert electrical energy into mechanical motion using electromagnetic principles. They typically consist of a coil, a magnetic core, and a movable armature. When an electric current flows through the coil, it generates a magnetic field that moves the armature, creating linear or rotational motion. These actuators are widely used in various applications, including electric motors, solenoids, and relays. They are valued for their precision, speed, and reliability, making them essential components in industries such as automotive, aerospace, and robotics. Their ability to control movement with electrical signals enhances automation and efficiency in many systems.
