Hi Wayne;

As you are learning servo engineering is or at least can be an
overwhelming task. It definetly helps to start out in these sorts of
adventures with someone on the team that is experienced. the reality
is that the task of implementing a servo system is logical and sometimes
simple, but the reality is that maximum performance is only obtained
with a bit of sweat.

It might help to pick up a textbook or two on motion systems. The
trick is to avoid the hard engineering texts. Also it pays to
subscribe to the trade magazines. I believe that Machine Design
publishes an annual handbook that you may find very useful. You
should be able to get the subscription for free, you may not get the
handbook for this year though.

I've worked on motion systems for years, as an automation tech, so I
can't say that an engineering degree is required to implement your
system. What I can say is that I have the highest respect for those
engineers that really understand this particular craft. There is
nothing more impressive than and engineer who can completely model his
intended system and then work with the nuances of the system in the real
world.

As far as your question of voltage goes the are many things to consider
not the least of which is the maxium RPM you wish to run the motor at.
That is if your implementing servo motors the issues with steppers is
differrent.

Thanks
Dave
