A d.c. shunt generator has 6 pole, 34 conductors, lap-wound, with terminal voltage of 210 volts delivering 11 amps to the load, has armature and field circuit resistance of 2 0, 200 ohms respectively. It is driven at 1000 r.p.m. Calculate the flux per pole in the machine. If the machine has to be run as a motor with the same terminal voltage and drawing 5 amps from the mains, maintaining the same magnetic field, find the speed of the machine.

Question
A d.c. shunt generator has 6 pole,
34 conductors, lap-wound, with
terminal voltage of 210 volts
delivering 11 amps to the load,
has armature and field circuit
resistance of 2 0, 200 ohms
respectively. It is driven at 1000
r.p.m. Calculate the flux per pole
in the machine. If the machine
has to be run as a motor with the
same terminal voltage and
drawing 5 amps from the mains,
maintaining the same magnetic
field, find the speed of the
machine.
