Rotary vs Static
Rotary vs Static
(OP)
I came across a 3 phase air compressor really cheap. Only 1 problem. I was curious about the pros and cons of static vs rotary converters. I know that static will reduce hp by about 1/3. Rotary converters however are 3 fold the price. I am not interested in wiring a ghost phase for fear of ruining my motor. A 10 hp in single phase is just as expensive as a rotary converter. There seems to be no economical way around this delimma. Please advise.

Also try persuading utiltiy co. to provide you a 3 phase service.

Stay with what can be fixed easily with simple parts and meters.

The computer technology works, and it is fairly reliable. My old retired computer from early 90ties still works and runs the old software pretty fast. It is also on and off pretty quick in comparison to current windows, e.g. XP Pro.
I would look at some static converters offered on web, e.g.

and type Converters: Phase under Product or Service, which will return 62 companies to approach to

Recently we helped one of our small machining vendors with exactly same problem. Purchased machine with 10 hp 3 phase motor but they only have 1 phase. Best method that time was VFD. Decision was based on ease of purchase and installation, requirements of the machine, and space available to mount equipment.
In your case however a single phase motor might be better as long as the cost of operation is not a big deal. If you start and run a single phase motor heavily 24/7 then not a good idea.
