Skeet,
I do not have my equipment installed yet, as my shop building at the farm is not built yet. But my plans are completed and my selected contractor has left the area and I am looking for a new builder. The converter came with the mill, a used setup. It is probably a rotary, being an older unit and I did not know enough to even know the difference, frankly. I am learning though. My main power line, goes across my property, is ¼ mile from the driveway and the shop will be over 500 feet from the drive/road intersection. No doubt our co-op will charge for a 3 phase and may not install it to start with. The part for concern is they have a very poor history of dropping power at various times of the day and I plan a full house 25KW generator on natural gas just for that exact reason. This site has an explanation of the different types of converters. I would take a light duty motor (.5 hp) explanation to be a lot different than a heavy duty motor like a 7.5 to 10 hp that is used as an example for their product. So I would simply use the data for info. http://www.phaseperfect.com/phasewhitepaper.htm This is a site that allows you to put in data that will search for your specific converter need: http://www.driveswarehouse.com/Drive...verter+VFD.htm
