  • Cheap AltTernative VFD motor ?

    So you have to run a VFD controller anyways right? and im thinking if this thing has enough power to propel a go-kart with person it would do fine on a small mill would it not?

    Perfect if you need to power your mill with 48VDC system on a rambulance.

    Speed controller is 99 usd and you still need also high power 48V power supply. Can be expensive and needs more hacking than just buying a ordinary VFD.

    "Normal" VFD also cant run "alternator motor" even if the motor voltage would match, you would need synchronous-motor capable VFD(preferrably sensorless)

        Just buy a VFD and 3 Phase Motor, then when one of them dies you won't have to spend a month in dumpsters hoping for the right bit of trash to repair yours.
        If you benefit from the Dunning-Kruger Effect you may not even know it ;-)

            That was a really neat hack. Don't know about the machine aspect, but it's a heck of a nice go-kart.
            John Titor, when are you.
