Because the spindle motor is meant to take 415V 3 phase. A 230v supply is
almost half that. Am I missing some blindingly obvious point that means a
single phase 230v inverter would work on the 415v motor? I thought the
inverter only changed the frequency of the current, not the voltage. Boston
Ficor said that most 3 phase motors that work on 460v are reconfigurable to
run on 230v 3 phase. Is this what you mean? I have to do all this wallying
because I don't have the money to make any £300 mistakes, I'm also
electrically retarded when it comes to VFD's. : )
