The
nominal field current is the current that produces nominal terminal
voltage under no-load conditions. This model was developed with all
quantities viewed from the stator. The nominal field current makes it
possible to compute the transformation ratio of the machine, which
allows you to apply the field voltage viewed from the rotor, as in true
life. This also allows the field current, which is a variable in the
output vector of the model, to be viewed from the rotor. If the value of
the nominal field current is not known, you must enter zero. Since the
transformation ratio can't be determined in this case, you will have to
apply the field voltage as viewed from the stator and the field current
in the output vector will also be viewed from the stator. Stat
