Tips: Can a 3 phase motor run on single phase power supply?
There is static phase converter that can provide a simulated three phase from single phase power supply, there is also rotary phase converter can do the job, the rotary solution seeming to be more reliable than static phase converter. Possibly the best way is to supply a Variable Frequency Drive (VFD), if you go with a VFD then you typically need to upsize the VFD (example a 10 hp VFD for a 7.5 hp application), this is because the input devices will be sized for 3 phase, and you will need 2 of them to carry 1.73 (square root of 3) more current, and your trough in the uncorrected resulting wave form will be deeper so you will need upsize the capacitance in the filter to fill this trough in.

Single phase VFD
Ah, finally find a VFD with single phase input up to 10hp, I can use it to convert my single phase power supply to drive my three phase motor now.
