torque is defined as the residual magnetism that remains in the rotor field poles that were operating at synchronous speed and the excitation current was removed.

Synchronous motors have the unique ability to drive a load and deliver reactive power to the same feeder line that powers the machine. This is accomplished by the excitation current so that the motor has a  power factor.

Please select the most correct answer from the list provided below.

What determines when a synchronous motor is at normal excitation?

This question is based on information derived from the Wildi textbook, Electrical Machines, Drives & Power Systems, Chapter 17.

While a synchronous motor is operating, a problem occurs with the power supply feeding excitation current to the machine. The machine continues to operate at synchronous speed despite the fact that there is zero excitation current being fed into the machine.

What is the reason behind this phenomenon?

Synchronous motors that operate at no load are commonly used for power factor correction. When used in this fashion, they are not considered motors but a Synchronous .

If mechanical load is added to a synchronous motor and the magnetic coupling between the rotor and stator is broken, what would be the result to the motor's operation?

How does an electrical worker go about changing the direction of rotation of a synchronous motor?

Please select the most correct answer from the options provided below.

Why must a synchronous motor never be started with the D.C. excitation current already applied to the rotor?

A popular strategy that manufacturers will use to increase the power output of a cylindrical rotor is to build a rotor with a longer overall length as opposed to increasing the rotor's diameter.

The ratio of excitation required to feed the magnetizing current to the field coils of the rotor which will produce the rated power output of the machine is quite small by comparison. According to the Wildi text, a 25 Kilowatt exciter will provide the current necessary to excite a 1000 KVA alternator.That ratio represents percent of the alternator's rating.
