This circuit operates like the one shown in Fig, 57-4, The only differences are that the field is placed across the rectified supply and the armature is placed in theSCRbridge. Thus the field current is unidirectional, armature current is reversible; consequently the motor`s direction of rotation is reversible.Potentiometer Rl controls the speed.
