Kay Industries Rotary Phase convertor with knife blade disconnect switch. 240V, maximum individual motor 7.5hp maximum total horsepower 22.5hp. Runs great and is still connected so you can see it in operation. It is about 20 years old and is probably due for new capaciters soon. That is simple to do and costs about $120. I'm in the Park City area near the junction of I-80 and US 40. Offers considered
