Question

what happens If "C1,C2"slip rings are not rotate along which coil in an electric motor

Answer 1

if the c1 and c2 rings aren't used...first of all there won't be any mechanical energy produced in the motor as the electrical energy is not being transmitted to the armature. secondly, if the slip ring commutator aren't used then the reversal ofdirection of the armature on rotating after 90 degrees won't be counterbalanced by changing connections of the terminals and hence the armature won't rotate in a single direction.

Answer 2

So the current be cant supply to the coil and after half revolution the coil stops moving
