You can use a regular 3-phase induction motor and a big run capacitor to 
convert single-phase power to 3-phase. You feed one phase of the motor 
straight off the line and another phase via the capacitor. The motor 
generates the third one. A lot of folk who buy surplus 3-phase machine 
tools use this trick.
