Converting 440v mill to 220v

I've been looking at old big fe mills recently, specifically Van Norman 22L's. At least ane of these has 440v power.

What would it accept to convert a 440v electrical motor and bulldoze system to 220v? Is this at all feasible??? I take 220 single phase and 3phase available in my shop.

Might at that place be some electrical components in the mill that need 440v to operate properly- hence a bargain breaker for converting to more than manageable 220...???

Thank you for any input or advice.

I may be wrong, merely you should exist able to merely rewire the motor (internally) to operate on 220 volts. You might find instructions inside the electrical box on the motor. Many are congenital accordingly.

Most 3Ø motors of that type are either dual or triple voltage: 208, 240, 480. The motor'south proper name plate should indicate how to wire it. The rest of the mill probably is 120.

the bugabo is information technology depends??? coolant motor, control transformer( oft easy) motor overloads, it will now draw twice every bit much current. and if no control transformer, roll southward in the starter relays may need to be changed

if the motor has been rewound information technology may merely take 3 leads out, then some looking will be necessary

Some OEM motors were 440V just. I took a laissez passer on a grinder that was that style. Grinder was a good deal if not for that voltage issue, but I merely didn't feel it remained a skilful deal if I needed to add a substantial buck/boost to the solution.

If your motor is 440V 3phase only, and you have 3 phase in your shop, I'm thinking a transformer to step upwards your voltage would exist all that is needed. I don't know the nameplate data (current) for your motor then I can't say how applied this solution might or might non be.

Yep, thank you all. I call back the transformer idea is the simplest way to go. The VN 22l got away to some other heir-apparent, so I am yet looking. However, information technology seems a lot of the big iron machines are all 440 or even higher voltage, so aforementioned result with compatibility.

I am limited to 10hp on my three stage RPC (5hp on the machine side), but that will power a pretty good size mill- bigger than I need actually. So ultimately hoping to find something that is 220 from the get go, yet still gives me decent vertical clearance. Siren call is still strong from some of these old high voltage mills, when you click on their page.
