A three-phase induction motor is an electric motor that operates using three-phase alternating current (AC) to generate rotational motion. It consists of a stator, which produces a rotating magnetic field, and a rotor, which is placed inside the stator. The interaction between the magnetic field and the rotor induces current, causing the rotor to turn. These motors are widely used in industrial applications due to their efficiency and reliability. They require minimal maintenance and can handle heavy loads, making them ideal for driving machinery, pumps, and fans. Their design allows for smooth operation and consistent performance in various environments.
