Hi All,
I'd love some help getting an English lathe (a Britan repetition) up and running. My shop has 220v 3 phase power. The electrical information on the machine tool says 380/440 volts 50 cycles 4-8 amps. The machine has a high and low speed, hence the two different amp draws. My power is 60 cycles. I believe that a VFD could make the change in cycles but I don't know if I really need to do that. It is expensive and I still would need to step up the voltage. There are no electronic components and I found a transformer on eBay that is: 7.5 KVA 3 phase primary 200/230 volts and secondary 346/415 50/60 hertz.
Could I run the lathe on this transformer? Would it hurt the motor or leave it underpowered. Perhaps I could take the motor in for rewinding to allow it to run on 220 v, but I'm afraid that I need the higher voltage to keep the motor's compact size. I'm sorry that all this is way beyond my knowledge base so I really appreciate any help you can offer. Many thanks,
David
