Dear phase converter owner: I have used a phase converter in my shop for the last 18 years. I also built a phase converter ( 5HP) for an aquantence of mine. Running single phase power to a 3 phase motor ( correct HP) & change it to a converter then 3 phase power comes
out of the 3 phase motor. This set up works very well. The start circuit consists of starting capacitors across 2 legs. This arangemest
is controlled by a contactor of which it is controlled by a 0-2 second timer..
The 5 HP converter I built I was able to get all 3 legs within 2 volts of each other. Balancing all three legs results in the lowest amp draw and motor will not heat up very much. Some time later I will send a schematic of how to do this project. Once one understands the function it is quite an easy project. The balance procedure is to get all 3 legs in the closest volt balance. This is done by adding AC Capacitors across the
legs in a particular fashion I realize that this may be hard to understand at this time but in the next week or so I will put a schematic in the "forum" area.
