I would like to design a variable frequency drive (VFD) to control
a small wind tunnnel exhibit for a science museum. The reason I think
this needs to be a (semi)custom design, is because of some of the
requirements in the user interface.
1. variable speed can be adjusted with a dial/pot.
2. specific speeds can be "remembered", i.e. setpoints
with buttons (3).
The motor is likely to be in the neighborhood of 1HP and 115VAC (1 or
3 phase), so relatively small. I know very little about the "art" of
VFD designs. I need help with the actual synthesis and driver electronics
(i.e. dealing back EMF,etc). I can handle the control part of it, if
I know what the parameters are.
Are there any good books or application notes about VFDs ?
Of course, if there are reasonably priced VFD that will do what I need
or is hackeable, that might be good too.
Thanks, -ingo
