In synchronous motor, minimum armature
current occurs at
Zero power factor
Leading power factor
Lagging power factor
Unity power factor
Unity power factor
The V curves of a synchronous motor are shown below,
The
point at which the unity power factor occurs is at the point where the armature
current is minimum.
Hence, the correct option is (D).
&Key Points:-
V
curve is a plot of the stator current verses field current for different loads.
