1. A separately-excited DC generator runs at 1500 rpm, supplying 240 V to a certain load. The ?ux per pole Φf is 20 mWb and the constant kNa equals 85. The armature copper losses are 600 W and the total brush-contact drop is 2 V. Calculate:

(a) the electromotive force
(b) the armature current
(c) the armature resistance
(d) the electric power provided to the load
(e) the torque required to move the generator

2. A 200-V separately-excited DC machine has an armature resistance of 0.3 Ω. If the armature current is 24 A, calculate the electromotive force:

(a) for generator operation
(b) for motor operation.
