WebBasic working principle of an Induction Motor. In a DC motor , supply is needed to be given for the stator winding as well as the rotor winding. But in an induction motor only the stator winding is fed with an AC supply. Alternating flux is produced around the stator winding due to AC supply. This alternating flux revolves with synchronous speed. http://educypedia.karadimov.info/library/motorfunds.pdf
