In the process of hunting when a DC generator (alternator) is subjected to a sudden change in load (in the stator) causes the rotor to hunt for a new equilibrium position (let us take the example of a pendulum when its made to oscillate with a general push it oscillate with a particular amplitude and frequency and after its oscillation, reaches the mean position, but as a certain load say 2gms is applied to the pendulum, oscillation changes and pendulum tries to attain a new amplitude and frequency as the applied load suggests) similarly in the case of alternator as the load changes rotor attains a new equilibrium position say of a particular degree(z)and the degree of rotation changes from (0 to 360 previously to 0+z to 360+z degrees with a new changed position) which refers to hunting in general sense.

Always remember in an alternator stator consists of armature windings and rotor consists of field windings and the main field flux is produced in the field windings (just opposite the case in an induction motor)...

Why is the frequency of a synchronous generator locked into its rate of shaft rotation?

By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.

Why synchronous impedance is not a constant?

Synchronous impedance is not a constant because it varies with operating conditions such as load, frequency, and machine construction. It is defined as the ratio of the voltage to the current at synchronous speed, but this relationship changes depending on the reactance and resistance of the machine as well as the power factor of the load. Additionally, factors such as saturation of magnetic materials and temperature can also influence synchronous impedance, leading to variations in its value.


Why the synchronous machine rotate at synchronous speed?

The spatial distribution of the windings in the armature is designed in a way such that it produce a rotating field when a three phase source is applied to its terminals. The field windings have a DC field applied to it and it is rotated mechanically by a prime mover. If the prime mover tried to rotate the synchronous machine at speed higher than its synchronous value then the power output of the generator will increase and this causes the speed to "lock" again to the synchronous one. If the prime mover applied less torque then the machine will slow down but the power output will decrease DUE TO DECEASE in the applied torque and this cause the machine to "lock" again to synchronous speed of the grid. The same principle can be applied to synchronous motors except that torque is negative (i.e. the prime mover is applying negative torque)


Why the no of poles are less in induction machine compared to synchronous machine?

The number of poles determines the speed a machine has to turn (RPMs). The more poles, the slower the machine can turn. I don't believe your statement is true. I've seen synchronous generators, for example, that turn at 1200 RPMS, and induction motors that turn at ~1800RPMs.

Why is the synchronous machine called a reversible machine?

A synchronous machine is called a reversible machine because it can operate in both motor and generator modes. In motor mode, it converts electrical energy into mechanical energy to produce motion, while in generator mode, it converts mechanical energy into electrical energy. This ability to switch between modes makes it reversible.


Why the synchronous motor is always a salient pole machine ie why don't we use a cylindrical pole machine as a synchronous motor?

The speed of the machine is tied to the power supply frequency and the number of poles the machine has. It becomes impractical to make a round rotor machine with many poles, so machines that spin at low revolutions will typically be salient designs. A two or four pole machine could be round rotor designs.
