Electric motors are electromechanical devices that convert electrical energy into mechanical energy. They operate based on the principles of electromagnetism, using the interaction of magnetic fields and conductors to generate motion. At their core, electric motors consist of a stationary component (stator) and a rotating component (rotor). The stator typically contains coils of wire that carry an electrical current, creating a magnetic field, while the rotor is designed to interact with this field and produce mechanical rotation.

Electric motors come in various sizes and configurations, catering to the specific needs of different industries. Whether it’s a small motor powering a household appliance or a massive motor propelling a train, these versatile devices serve as the workhorses of the industrial world.
