Unisaw Voltage/Wiring Question-250v

[Model A Fan]

So a Unisaw popped up locally for pretty cheap:

What I'm wondering is what does the 250v mean? I've got 220v and 110v in my shop, but don't have "250v".

Any info you might be able to shed on the topic?

Thanks!

In the US we actually have 120/240 unless you are having a low voltage situation so I believe you would be just fine

Being from a college, it's very likely a 3 phase machine, and a typo - should read 230 or 240V.

If you can't handle 3 phase, you could swap out the motor for a 1 phase. Contact the seller to clarify.

Sounds like more hassle than its worth at this point. I was contemplating a large table saw because the price was good, but I don't have the space in my garage if I can't use it as is without swapping stuff around...

I'll wait and buy one later even if I have to pay more. I'm in a 20x20 garage with a Model A partially disassembled right in the middle...

You can run it on 115V, or 230V, single phase. It pulls 24 amps at 115 volts, or 12 amps at 230 volts. If you are uncomfortable wiring a dual voltage motor maybe you have an electrician buddy?

What's the worst that can happen? Lol

That's a nice saw. Don't forget you'll have to buy a fence for it.

Thank you, I couldn't figure out how to access them. It looks like it is missing the cover and sawdust would blow everywhere.

I didn't know the motor could be rewired as I couldn't find photos of it.

Well, search for one of my previous threads showing my garage and look at the mess. I'm in a 20x20 and have far too much stuff crammed into that size of space. I've got a saw already, so I think I will make due.

That's a nice saw. Don't forget you'll have to buy a fence for it.

And that would be another expense...

What is the approximate age and value of this type? I like it has the metal cranks. Is that standard? I should probably do some research on the unusable before I buy one...

definitely not the original motor. 34-450 is late 60's early 70's vintage. nice that it has both CI wings, the door was probably tossed when they changed the motor out. I found a NOS one for mine on ebay in the wrong color for a fair price, but before I did, I just made one out of plywood, which is fairly common to do.

I would say without a fence and only 2hp motor, it's worth around $400, and you can easily spend that on a good fence. keep in mind if it was a school or industrial use, you may be spending money on replacing the bearings/belts and such (especially if they already wore out the original motor).

In the US, single phase power is normally has a nominal value of 120/240V.
BUT it is normal to see 115/230V on motor nameplates.
AND to make matters more confusing, 125/250V is the convention when rating plugs/receptacles.

So, if someone read 250V off of something, they had to have read it off of the plug.

Details state fence comes with it. Both cast iron wings is a plus. 2HP is a bit small, but I would bet it will outrun any newer "Chinesium" 3HP motor, especially wired on 240V. Plenty of oomph, unless you're ripping 12/4 hard maple or something like that.

I'd go maybe to 5 bills, and don't forget your 15.7% "taxes/buyers fees/premiums etc"

^ ^ ^ ^ +1 to make sure to REMEMBER all those add on fees/taxes.

Recently bought item on GovLiq for $81 and after Buyer's Premium/Tax the total was $105 . . . . . which is over 25% !!!

It's because they STINKIN' TAX the Buyer's Premium so it's double whammy.

If you rewiire the motor for 115v (110/120v), you should have a dedicated 30a circuit to run the saw on. The startup amps are higher than the rating on the motor.

HOLY COW! It sold for $756! Needless to say, I didn't think it would sell for that much.

Thanks for the input guys. I will keep plugging away with my saw and keep looking for that "perfect one".

considering a new one is $3k, that's actually not a bad deal. I've seen them go cheaper occasionally (especially 3phase units), but more often than not $1500 is an average deal...
