  Several VFD's (Variable Frequency Drives) are available with single phase 
120/240 vac input and 240/480 vac 3 phase outputs. These VFD's are 
specifically designed for water pumping and have programable soft start . 3 
to 5 hp drives are not too expensive. I have used a Toshiba VFD . Works 
great! You can even change motor direction to clean out pumps.

Just a thought.
