A three-phase induction motor is an electric motor that operates using three-phase alternating current (AC). It consists of a stator, which generates 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 and produce mechanical power. These motors are widely used in industrial applications due to their efficiency and reliability. They require minimal maintenance and can operate at various speeds. Common applications include driving pumps, fans, and compressors, making them essential in many manufacturing processes.
