A 4-pole separately excited dc generator has 310 armature conductors and runs at 1200 rpm. The machine is
excited by a 220V d.c. source and the cmf generated is 400V. The armature and field resistances are 0.5fi and
200i2 respectively. The machine is used to supply a load of 50A . Calculate:
a) The flux per pole
—b) The terminal voltage
Cl The power delivered to the load
d ) The excitation current
e) The excitation power
