Good morning everyone, i recently purchased a cnc kit that includes a 2.2kw 110v vfd as well as a 2.2kw 110v spindle. Now, im not an expert, but the spindle manual states it can only take 8 amps. By my calculation thats only 880watts of power. Am I missing something here? How is the 2.2kw power rating arrived at? I know the output of the vfd is 3phase. Is it not as simple as saying 110v *8a = 880watts? Does each leg of the 3phase carry close to 8 amps? Any advice would be appreciated.
