IF this Machine is being purchased from the Manufacturer. I will be wired for single phase if requested. The only 3 phase motor on a Fadal with out spindle thru coolant is the spindle motor. How ever it is powered by an Inverter which when wired correctly (done at factory if purchased that way) can run a three phase motor from a single phase sorce. It will also have a single phase transformer with it to step down your line voltage to the 110vac to run the solenoids and relays as well as 5vdc powersupply for the control. As for power a 65 amp circuit running off your 240volt 200 amp box should be adequate expensive but adequate. As some else mentioned Horse Power is Horse Power so once at speed there will be no noticable difference what you will see is in rush problems. When you turn on the spindle, and rapid two or three axis simultainiously. And the load on your line at your main panel is up there (your doing laundry and using an eletric dry, water heater, have all the televisions in the house on and someone is blow drying their hair, you'll see a dip in voltage or a brown out occurance. IF this is a normal 200 amp main, you shouldn't see any of this if your miserly in the use of other electricals around the home.  |
