Hi...as Geno says 3 phase power is good , if you need it for your equiptment.
However "these days" for somewhere around $400 you can get a 1 phase to 3 phase converter ( VVVF drive ).
For that sort of coin, you get a top name brand unit that can run stuff at whatever speed you like from virtually 0rpm to 10 times its normal speed ( should you be feeling brave). Reversing direction is easy as ,too.
If you just want a bit of 3 phase power, it can just be left set at 50 hertz ( as per what you get from the supply authority)
Like all this stuff, there is more to consider before you race out and get one, and wire it up.......however, for say, a 1.1kw 3 phase motor, you no longer actually need a 3 phase supply at all.
Think of all those big heavy sliding steel gates in industrial areas...most are supplied from no more than a power point, but have a 3 phase motor attached to their gearbox. The VVVF drive converts the supply to 3 phase.
The speed is just tweaked by a keypad / or a PC until you are happy.
