Guys   I'm sure I should know the answer to this, but just can't seem to find anything in my literature or on the web.  A friend (G7ODR, cc'd on this email) and I have scratched our heads, but the mo

I run my 3 phase 208V shop equipment on 240V single phase. A 7.5hp 3 phase motor and a compensating cap are used to achieve this. The motor is used as an idler so it isnt performing any work. There s

Carl Many cases you don't even need the motor in the phase converter The three phase transformer will problably work fine with just the capacitor to the wild leg which was already suggested. Especial

It wont work with my 5 hp 2 stage compressor, South Bend lathe, milling machine, or MIG and TIG welders. With motors they lose a lot of torque. If I ever get a surplused AM BC transmitter I'll give i

Hello, This question could not have come at a better time. I am currently trying to do the same thing with a plasma cutter I purchased this weekend. It turns out the unit I thought was 220v single ph

Multi purpose industrial xfmrs are rather easy to find at scrap dealers and surplus stores. I use a pair of 5KVA Westinghouse 240 to 480V units to feed the garage and step down again. Cuts losses in

Dave, If you parallel two of the three primary windings fed with 240V single phase, and series the two corresponding secondary windings, I believe you would get about 4376V, 8kVA (4kVA per coil). Thi

I should also clarify that this is only if the rated primary voltage is 380V, not 415V. Jim Smith, KQ6UV _______________________________________________ Amps mailing list Amps@contesting.com http://l
