Answer / naresh chandra jha

For any rotating machine number of stator pole should be
same as number of rotor pole . 3-phase induction is single
exication self starting motor .Thus for 3 -phase stator
winding and 3-phase supply same number of pole will induce
in stator winding and hence motor will start run .

Answer / deepak24

If the no. Of rotor pole is not eqal to tha stator pole then it will not run. No. Of Stator pole and rotor pole must be same to run 3 phase induction motor

Answer / vijukumar

yes the statormay have many pols the rotor will have only one
pole as it act as aclose circuit
