Answer / ganesh kumar mynampati
when number of rotor poles and stator are equal there
exists interlocking which meansstatot teeth and rotor poles
get attached to each other which eventually brings the
motor to rest.

Answer / sujoy roy
On the above case the speed of rotating magnetic field
is "synchronous speed".And the speed of the rotor is less
the synchronous speed,which depends upon slip.

Answer / mahesh
if the no. of stator poles are equal to the no. of rotor
poles, torque will be zero. because stator poles attract the
rotor poles since there is no RMF in DC.. In case of AC
motors this problem is not present
