Will a single phase motor use less power than a 3 phase motor?
I am in the process of selecting a farm duty high torque 2 hp electric motor for a small "pilot mill rock "ore" crusher. At my house (garage) I only have 115v outlets. I have a friend that is a licensed electrician and he said he could come out and wire a 230v single phase outlet on a 30 amp breaker so I could use a 230v single phase motor I was interested in using. The motor has a manual overload protection circuit rated at 9.5 amps and rated at 14amps at full load @230V. It gets confusing because some websites selling motors that only show "nameplate amps". Now I also looked at 2 hp, 3 phase motors that the amps run @ 5.6 amps but I don't think that is at "full load" Anyway, if I could get my garage wired for 230v single phase and then use a VFD, is it possible to run a 3 phase motor? And would it be cheaper on my power bill compared to using the single phase motor that I have selected? Thanks for any and all help!
P.S. I cut it twice and it's still too short! LOL
