V curve is a plot of the armature current versus field current for different constant loads. The armature current changes with the change in the field current. When the motor is running under no load, if the field current is increased, the armature current decreases until the armature current becomes minimum. At this point, the motor operates at unity power factor. The motor operates at lagging power factor until it reaches up to this point of operation. If now, the field current is increased further, the armature current increases and the motor starts operating as a leading power factor.
