Can you suggest a circuit diagram for voltage regulation of 3 phase permanent magnet alternator for a constant output 230volts?

The normal method for controlling output of an alternator is to vary the field current. In a PM alternator, there would be no field windings to control. The only way I could think of would be to vary the speed of rotation. This might work if the output was rectified (DC), but would be a problem if the output is AC, since the frequency would also change. I have not seen a PM alternator per se. Unusual.

Line regulation and load regulation of zener diode?
Line regulation defines as the output voltage of the zener to remain constant under input line variation. Load regulations defined as the load increases or decreases the zener will control this variation by keeping the voltage constant.
Why dc shunt motor known as constant speed motor?
A shunt motor isn't literally constant-speed; its speed does fall between no load and full load. If you plot a graph of speed against load, you will find that the speed falls by around 10% or so. Compared with other d.c. motors, this fall is considered to be insignificant -hence the term, 'constant speed'.We apply a similar term to transformers, when we describe them as being 'constant voltage' machines. They're not literally 'constant voltage', but their regulation (difference between full-load and no-load voltage), is considered to be insignificant.

How do you calculate the time constant for a simple series RL circuit?
The time constant of an RL series circuit is calculated using the formular: time constant=L/R
Is mutual flux in transformer constant for all loads?
The flux is set by the voltage applied to the transformer. In most applications, the voltage is constant, and therefore the flux is constant also.
Why is voltage regulation important in alternator?
because the voltage should be constant as the full transmission grid need ame voltage for synchronization of alternatos of grid
What does the homeostasis do?
Homeostasis is the regulation of internal biochemistry to maintain a constant internal environment. Without this constant regulation, living organisms would be unable to function. Therefore, homeostasis is the regulation of the internal environment of the body, and also the maintenance of this constant environment. Hope this helps!

Why is my 1984 alternator charging constant 16.3 volts?
If the battery checks out okay, you can replace just the voltage regulator inside the alternator.
C plus plus program to add a letter in a permanent letters alphabetically?
If by permanent you mean constant, you cannot change something that is constant, therefore you cannot add to it (letters or otherwise). It has to be variable. Constant and variable are mutually exclusive terms.
Why is it necessary that the speed of an alternator be mentained at a constant value at all time?
