So the main issue is having large enough caps which should be stated.
I've been thinking some more about the possibility of a text about power supplies and the problem is that I keep running into more questions which leads me to think that it needs an entire Thread of its own.
For example does the piece I have quoted mean that it is a good idea to attach a very large capacitor to a regulated power supply as well as to an unregulated supply?
And, to confirm my understanding, I have 3 motors that each have a coil current of 0.33 A. That would mean 0.99A for all 3 - say 1.5A to give a margin. And, supposing they are powered at 20v your formula would be
80,000 * 1.5 / 20 which gives a capacitor value of 6,000 microFarads.
And without intending the least disrespect to your knowledge I have not yet got any sense of how much difference it would make to have an unregulated rather than a regulated power supply with the same voltage assuming both can deliver enough amps.
