They used to make a convertor to run a three phase motor on single phase, but with reduced torque. Unbalanced current on the artificial phase. |

Now a days VFDs do the job....Full wave rectify into a BIG capacitor bank then invert the DC into 3 phase.

Larger VFD's still need three phase power. They make smaller VFD's for single phase, lower voltage, 120/208/240 volts, probably a maximum of 3 HP (2.2 KW). They work great. |
