   I'm assuming you only have single phase. Then you will need a phase converter.With a converter you will have issuse like, Where will you place it. Turning it. For table saw work some times you work the saw along time and some times it's on/off short times, will you leave it on during the short times ? Extra noise. Onther than that there great. I have one for my drill press and recently 16" jointer.It's not so bad to work this converter since these machine are not used every day. for the space problem, I built a cart on casters for it that fits under the drill press table. the table is set at it's normal hieght. The cart holds a 7.5hp converter, 3ph sub pamel and drawers for drills an assc. Good luck Rick

   Is this converter the same thing as a VFD, as was recommended by RickL? Or is it a different beast?

   Irontoys is talking Rotary Phase converter. You can run multiple horse power machines on one. More expensive than a VFD unless you cobble up your own. There's a lot to this phase conversion thing but the VFD is the simplest and cheapest for a single machine to give full power. The staic is cheaper and simpler but only yields 2/3 hp.

   Thanks for all the info...I think I can now make a "fairly" intelligent decision on the purchase.

   You are talking about only one of several ways to get three phase power when only single phase is available. The other options, a VFD or a static converter are much smaller and lighter in weight and can be installed directly on the machine or wall mounted.John White

   Hardly an obstacle. For one machine a VFD from http://www.factorymation is the cheapest way to go. Takes care of motor and switch issues in one purchase. Don't go by the chart. Have a tech size the proper VFD. Some of the ones on the chart are pre-derated for single phase input while others are not. Typically someone starts making uneducated comments on the units because the don't really understand. Of course the company adds to the confusion by not having an explanation of derating.
