Induction Motor Interview Questions: Part 1 - Blogger

Jun 04, 2014· Basic Interview Questions on Induction Motors: [Q] How does the Induction motor work? (OR) Why does the Rotor rotate? When the 3 phase stator windings are fed by 3 phase supply, a magnetic flux of constant magnitude which is rotating at synchronous speed is set up.Three Phase Induction Motor Interview Questions & Answers,,What is the Three Phase induction motor Working Principle? Like any electric motor, a 3-phase induction motor has a stator and rotor. The stator carries a 3-phase winding (called stator winding) while the rotor carries a short circuited winding (called rotor wind­ing). Only the stator winding is fed from 3-phase supply. The rotor winding derivesTop 250+ Induction Motors Interview Questions - Best,,Question 1. What Is An Induction Motor?
