| I've got just a system, rather old, and added to piece at a time. With a 400 amp service I can run about 50 hp of motors at any one time. If I was starting over I'd seriously considered 3 phase either from the power company or from an inverter. One down side is the higher cost of single phase motors and the occassional problem with capacitors. Another problem is while you can get a 15 hp 3600 rpm fan motor you're limited to 10 hp on 1750 rpm auger motors. I've got an 8" sweep/truck loading auger that I can't run to full capacity with only 10 hp. I did see where Baldor (very good motors) now has a 15 hp 1750 rpm single phase motor but the list price was $4800. | |
