I have a 1 1/2 hp 220 V 3 phase motor that I will be using to power the spindle on my homemade cnc mill. I now need a VFD for it.
Currently I only have 110V power in the shop so ideally a 110v single phase to 220 v 3phase drive would be best. However, the closest drive I find that meets that is only rated at 1hp. Anything bigger is 220 V single to 220 V 3 phase and thus I would have the extra expense of bringing in 220 v single phase power. Doable, but not overly appealing as we have the house up for sale and would like to move this summer.
What would be the downside of using a vfd rated for 1 hp to power a 1 1/2 hp motor?
