Hi guys, I have a Sheldon shaper and a Nichols mill, both will run on my VFD. I do have to change settings on the Freq Drive, because the shaper runs a 1-1/2 horse motor, while the mill has a 1 hp motor. Part of the info plate on the mill has been scratched, but the only part really affected is the voltage listing. Theamps for the 1 hp motor clearly shows it being 1.28 amps, and clearly shows 1 hp. If I calculate 1.28 X 220, / 746, it equals .37 hp. With 3 phase, do I realy need to multiply the amperage reading by 3 to get actual amperage for the VFD setting. The 1-1/2 hp motor has a much higher amperage of 4.8 for 220 volts equaling 1.41 hp.
I hope my question is clear enough, it just seems as though one motor is rated one way the other another way. #.84 seems a lot closer to me than 1.28 for setting the ratings.
Thanks for looking, and especially thanks for replying.
