If your load is fairly constant, you can use passive components to make a 'fooler box'.
Small single-phase to 3-phase inverters are readily available and inexpensive on ebay.

They are called VFD's and are a low cost commodity item. There is no possible way you could build one for the selling prive.

A Scott-T transformer can convert 2-phase to three phase, not single phase to 3-phase, and no, the line voltage in US/Canada homes is not two phase, it's single phase with a centertap.
There are a few approaches:
- static phase converter
- rotary phase converter
- synthesize the three phases with electronics (inverter)
As Don L. says the three phase inverters are low-cost commodity items (okay, also extremely costly military and aerospace items!) and you can purchase them off-the-shelf, in high and low power and high and low voltage versions.
