Speed control of d.c. Motors:Thyristor Speed Control of Separately-excited D.C. Motor

Thyristor Speed Control of Separately-excited D.C. Motor In Fig. 30.32, the bridge rectifier converts a voltage into d.c. voltage which is then applied to the armature of the separately-excited d.c. motor M. As we know, speed of a motor is given by If F is kept constant and also if a is neglected, then, N […]
