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 2, 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 Q, 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.
