What is the working principle of an induction motor?
Understand the Problem
The question is asking for an explanation of how an induction motor operates, which includes the principles behind its functioning, such as electromagnetic induction and rotor motion.
Answer
An induction motor works on electromagnetic induction, where a rotating magnetic field created in the stator induces current in the rotor, producing torque and causing the rotor to spin.
The working principle of an induction motor is based on electromagnetic induction. When an AC current is supplied to the stator winding, it creates a rotating magnetic field which induces a current in the rotor. The interaction of the magnetic field and rotor current produces torque, causing the rotor to turn.

More Information
Induction motors are popular due to their simplicity, rugged construction, and relatively low cost. They are widely used in industrial and domestic applications.
Tips
A common mistake is confusing the synchronous speed with the rotor speed. The rotor always rotates at a speed slightly less than the synchronous speed due to slip.
