Hello All,
I am looking at a used lathe in great shape, but would surely want to convert it to VS rather quickly if I get it.
From my search on this and other sites, it seems that going to VFD with a 3phase AC motor is the preferred way of doing this. Treadmill motor is a much cheaper option, but I don't seem to get as much positive vibe from that.
Anyway, when looking at my options, it seems there is a huge range of prices for 1HP 3Phase motors. Is there something I'm missing, do I need anything particular? Some motors (on ebay) are around $65-$100, while others, seemingly simlar are well over $200. Why the differnece??
Does anyone know of a good source for a motor?
Also, I found a VFD for just over $100 at dealerselectric.com/mfg-subcat-item.asp?cID=28&scID=164&mID=-1. Anyone ever buy from them, seems like a good deal?
Finally, those really are the only 2 items I need, correct? It sounds like I might need someone much better versed in electronics to set it up for me, but as long as I know the components necessary to get VS.
Thanks for the insight. All of this will have to be considered before I pull the trigger on this lathe.
thanks!
