A synchronous motor installed at the receiving end substation operates with such an excitation that it takes power at lagging power factor. Now if the applied voltage of the synchronous motor goes down, the power factor of the synchronous motor will
As the load is applied to a synchronous motor, the motor takes more armature current because
When load on an over-excited or under excited synchronous motor is increased, rate of change of its armature current as compared with that of power factor is
The armature current of the synchronous motor has higher values for
In a synchronous motor, the armature current has large values for
A synchronous motor is running with normal excitation. When the load is increased, the armature current drawn by it increases because
The minimum armature current of the synchronous motor corresponds to operation at
If excitation of a synchronous motor running with a constant load is decreased from its normal value, ignoring effects of armature reaction, it leads to
The net armature voltage of a synchronous motor is equal to the
In a synchronous motor it the back e.m.f. generated in the armature at noload is approximately equal to the applied voltage, then
