Induction motor we are giving three phase ac power supply to statar windings so magnetic field induced on statar windings this magnetic field cut the rotor winding its single winding with shorted. So emf induced on rotor winding rotor is closed winding so current is produced on rotor winding this current make more magnetic field so there is interaction between both magnetic field.so easy to rotate construction of rotor rotate force of stator magticfield.when rotor rotate there is produce the end is called back emf.there is any position called resistance but it's AC machine so it's called impedance

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
