Q6. (a) Describe the basic principles of self-excited generators. (6)
(b) The armature resistance of a 200 V, shunt motor is 0.4 ohms. The no-load (this is the term used when the motor is running light, i.e. not loaded) armature current is 2A. When loaded and taking an armature current of 50 A, the speed is 1200 rev/min. Find the approximate no load speed. (10)

(b) The armature resistance of a 200 V, shunt motor is 0.4 ohms and the no-load armature current is 2A. When fully loaded and taking an armature current of 50 A, the speed is 1200 rev/min. Find the no-load speed and state the assumption made in the calculation. (10)
