Question

In synchronous motor, minimum armature current occurs at

A.

Zero power factor

B.

Leading power factor

C.

Lagging power factor

D.

Unity power factor

Answer ( Option D)

Unity power factor

Solution

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.
