1 Explain with the help of a sketch, the constructional features of a
dc machine and briefly describe the functions of armature core,
commutator and brushes. (13)

2 (i) Briefly explain about the principle of operation of DC
generator.(6)
(ii) Arrive at an Emf equation of DC generator. (7)

3 A six-pole, lap-connected generator is driven at 600rpm. It has 100
slots with 24 conductors per slot. What is the magnitude of the
generated emf? If the number of conductors per slot is changed to
20.At what speed should the generator be run for the same voltage
to be generated? The flux per pole is 0.02Wb.(13) (BE8255 important 16 Mark questions Basic Electrical Electronics and Measurement Engineering)
