RE: three phase motots
If more than one or two kW, three phase is usually preferred. Starting torque for a single phase motor is usually low, fans need low starting torque. Single phase motors are not available for high kW applications. Price starts getting high in comparison when kW gets above a few kW.

Don't considerate the transformer availability or the size of the cable in your answer.
