A single-phase half-controlled rectifier is driving a separately excited dc motor. The dc motor has a back emf constant of 0.20 V/rpm. The armature current is 6 A without any ripple. The armature resistance is 2 ohm. The converter is working from a 230 V, single phase ac source with a firing angle of 30°. Under this operating condition determine the speed of the motor.
