An electromagnetic clutch is a device that uses electromagnetic force to engage and disengage power transmission between two rotating shafts. When electrical current flows through a coil, it generates a magnetic field that attracts a metal plate, connecting the input and output shafts. This allows for smooth operation and control of machinery. These clutches are commonly used in various applications, including automobiles, industrial machinery, and home appliances. They provide advantages such as quick response times, reduced wear, and the ability to control torque without mechanical linkages. This makes them ideal for systems requiring precise control and reliability.
