In a synchronous motor the back e.m.f. generated in the armature at no-load is approximately equal to the applied voltage, then A) The motor is said to be fully loaded B) The torque generated is maximum C) The excitation is said to be zero percent D) The excitation is said to be hundred percent Related MCQs: When the voltage applied to a synchronous motor is increased, which of the following will reduce If in a synchronous motor, driving mechanical load and drawing current at lagging power factor from the constant voltage supply, its field excitation is increased, then its power factor Which of the following losses in a synchronous motor does not vary with load One D.C. motor drives another D.C. motor. The second D.C. motor when excited and driven
