Electric motors are devices that convert electrical energy into mechanical energy. They work by using electromagnetic principles, where electric current flows through coils of wire, creating a magnetic field that causes a rotor to spin. This spinning motion can then be used to power various machines and appliances, from small gadgets to large industrial equipment. There are different types of electric motors, including AC motors and DC motors, each suited for specific applications. AC motors are commonly used in household appliances, while DC motors are often found in battery-operated devices. Overall, electric motors play a crucial role in modern technology and everyday life.
