Hello everyone
I have just bought a new lathe, (used) its on its way to me from other end of the country now.
I have only just realised i may have an issue.
The machine is 3 phase and i was intending to go down the VFD route but because its a dual speed motor im not sure i can.
See attached image of motor name plate.
It also says its 380 rather than 400v, its an old machine so maybe thats normal?
My workshop supply is split phase, 2x100a incomers on a 3 phase cutout, no 3 phase available near me.
I have the offer of a little used transwave 5.5kw static converter, but im not sure if itll work either.
Any help is much appreciated
Thanks
Robert

cheepest way of doing this would be to put a single phase motor on it.
If you need speed control, then go for a 3 phase dual voltage motor with a single phase vsd.

I have thought of that but i have heard people say that they dont last being that size and there isnt as much torque per KW, not entirely sure myself (hence the reason i am asking)
On another forum where i was asking about the lathe its self i posted this very question and they mentioned that i could use the 2 phase supply coming in, through a transformer and make the 3rd phase? is that do able?
Thanks
Robert
