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.
