Re: Motor calculations? Help!

Yeah I ordered those rutex drives on Thursday :) I also figured out
that the original power supply transformer is a 2.5 KVA. From
talking with Marris at geck I pretty much concluded I could go with
a 100 VDC 15 Amp power supply. The total rated output of all 3
motors combined is 2000W. In realty when are you ever going to move
the machine in a way that will need all that torque. If your cutting
something with that much force something is going to be broken. Heck
70 watts would probobly work one motor hard enough to cut.
