Electric motors are devices that convert electrical energy into mechanical energy. They are widely used in various applications, from industrial machinery to household appliances. Electric motors work based on the principle of electromagnetic induction, where the interaction between electric currents and magnetic fields generates a rotational force. They consist of a stationary part called the stator and a rotating part known as the rotor. The stator contains coils of wire that produce a magnetic field when an electric current passes through them. The rotor, typically made of magnets or electromagnets, experiences a force due to the interaction with the magnetic field, resulting in rotational motion. Electric motors are available in different types, including AC (alternating current) motors and DC (direct current) motors, each suited for specific applications. They offer advantages such as high efficiency, precise control, and reliability. Electric motors are essential components in a wide range of devices, from electric vehicles and industrial machinery to fans, pumps, and household appliances, playing a significant role in modern technology and automation.
