induction Motor is AC motor, may be three phase or single
phase,in which rotor has no direct electrical
connection,the rotor rotate by induction effect of stator
winding.

Answer / sayed asef

induction motor is electrical machine which convert
electrical power to mechanical power .same like transformer
primery and secondry winding.stator is primery and rotor is
secondry winding.when you give the electrical power to
stator it produced free rotating flux in between air gap.
