Looking for VAX6000 items

A number of the large disk drives use 3 phase motors; RP04/5/6 are examples as well. Three phase motors won't run on single phase power without help from run capacitors. (There is no such thing as "two phase power" -- 220 volts is single phase, balanced.) If the issue is motors, a "variable frequency converter" will do the job easily. I have suggested in the past that three phase power supplies could run from those, but others have pointed out I overlooked some issues. So that's probably not a good idea. If you need three phase power to feed power supplies or other non-motor power consumers, the best answer is probably a "rotary converter". You can find those in machine tool supply catalogs. Basically they are a three phase motor equipped with run capacitors so they can be fed single phase power; the three phase power needed is then taken off the three motor terminals. You can think of these as rotary transformers -- dynamotors in a sense, for those of you who remember electronics that old. :-) Don't look at "static converters" -- those are only for motors, it seems they aren't much more than run capacitors in a box. They won't help you for anything other than a motor, and even for motors they aren't very good. paul
