A three-phase induction motor is an electric motor that operates using three alternating currents, which create a rotating magnetic field. This design allows for efficient energy conversion and is commonly used in industrial applications due to its reliability and simplicity. The motor consists of a stator, which generates the magnetic field, and a rotor, which turns in response to this field. The rotor in a three-phase induction motor can be of two types: squirrel cage or wound. The squirrel cage rotor is more common due to its robustness and low maintenance requirements. These motors are widely used in various applications, including pumps, fans, and conveyors, making them essential in modern industry.
