A magnetic clutch is a device that uses magnetic fields to engage and disengage power transmission between two components, typically in machinery. When an electric current flows through a coil, it generates a magnetic field that attracts a rotor, allowing it to connect with a driven component. This mechanism enables smooth operation and precise control of power transfer. These clutches are commonly used in various applications, including automotive systems and industrial machinery. They offer advantages such as quick response times and reduced wear compared to traditional mechanical clutches. Overall, magnetic clutches enhance efficiency and reliability in power transmission systems.
