Question: A 4 - pole, 3 2 conductor, lap - wound de shunt generator with terminal voltage of 2 0 0 volts delivering 1 2 amps

A 4-pole, 32 conductor, lap-wound de shunt generator with terminal voltage of 200 volts delivering 12 amps to the load, has armature resistance of Ra=2 and field circuit resistance of Rf=200. It is driven at 1000 rpm .
(a) Draw the equivalent circuit as generator.
(b)(i) Determine the field current, If as a generator.
(ii) Determine the armature current, Ia as a generator.
(iii)Determine the induced emf, Ea as a generator.
(c) Determine the flux per pole.
(d) The machine has to be run as a motor with the same terminal voltage and drawing 5 amps from the mains, and maintaining the same magnetic field.
(i) Draw the equivalent circuit as motor.
(ii) Determine the armature current, Ia as a motor.
(iii)Determine the induced emf, Ea as a motor.
(iv) Determine the speed of the motor.
