The model engineering people  running 3 phase motors  use either
capacitive splits (so not true 3 phase) or inverters, or (a very few), motor
generators.

My inverter (for the mill and the lathe) can be bought for about $250 over here,
and 
will provide variable frequency drive (thus variable speed) for a 1hp machine -
it's 
about 850 watts continuous output. It's in a box about 6 inches by 5 inches by 
3 inches. Output powers up to abt 3kW are available from large units.
