Anyone ever taken apart the 1960's type manual Maho MH600/700 and looked at the feed motor?
Due to a problem with the main 2 speed spindle motor I'm swapping that out for one driven by a single phase VFD outputting 220v 3 phase.
The feed motor is also two speed 415v 3 phase and is buried right in the guts of the machine. I'm curious if anyone has changed the feed motor as well, or perhaps converted it to run on delta (220v 3 phase) before I start burrowing in. I suspect that it's probably bespoke/integral with some other parts and therefore a problem to swap out. I could run the spindle via single phase & VFD and the feed via 3 phase & rotary converter but that's not very elegant. I'd prefer to replace both and wire it all in neatly.
