There is also Power Electronics Technology magazine - powerelectronics.com
I would be more inclined to repair the old drive. Unless it has suffered
really extreme damage, this would probably be much easier than designing and
building a new one. No manual? - reverse engineering it would teach you a lot
about drive design. Start by finding data sheets and app notes for whatever
power semiconductors the drive uses.
