in synchronous machine v curve explain please
Answer (1)
Hello Aspirant,
Thanks for approaching us
V curve is a plot of the stator current versus field current for different constant loads. The Graph plotted between the armature current I
a
and field current I
f
at no load the curve is obtained known as V Curve . Since the shape of these curves is similar to the letter “V”, thus they are called V curve of synchronous motor.
The power factor of the synchronous motor can be controlled by varying the field current I
f
. As we know that the armature current I
a
changes with the change in the field current I
f
Hope this helps you
Feel free to ask any question.
All the best for your future
