Q1. What is working principle of induction motor
Ans. 
Induction motor works on the principle of electromagnetic induction to generate rotating magnetic field.
• Induction motor has a stator with a set of windings that are connected to an AC power supply.

• When AC current flows through the stator windings, it creates a rotating magnetic field.

• This rotating magnetic field induces currents in the rotor windings, causing the rotor to rotate.

• The rotor never reaches the synchronous ...read more
