Lifelong India Production Engineer Interview Questions and Answers

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
