Elements and Working Principles of AC Induction Motors
Key Physical Components of the AC Induction Motor
The AC induction motor is made up of two main components: the stationary stator and the rotating rotor. The stator houses winding circuits that generate a rotating magnetic field, while the rotor responds to this field, producing motion and ultimately, mechanical power.
Explanation of the Operation and Working Principle
The core of an AC induction motor’s operation lies in the interaction between the stator’s magnetic field and the rotor. As alternating current flows through the stator, it creates a magnetic field that induces an electric current in the rotor, causing it to rotate. This continuous interplay between current and magnetic fields powers the motor.
