I have a chance to by a 10”’ Delta Unisaw with a Vega fence for 300$ but needs a new motor. Can I get a new 110V motor for it that will work?
Here is the description.
Older very heavy Cast iron 10” Delta table saw They don’t make them like this any more the saw itself is in great shape but needs a motor. Has a Vega 50” fence with extension table that attaches but not shown it is to big to set-up. The Vega fence is listed $375 new. This one is used but still worked awesome. Selling cause I need to de-clutter and have been intending to repair this over a year. So if you have the time you will end up with a great tablesaw.

You can get a motor lots of places, but they use a Unisaw specific mount, and are different depending on if it’s left or right tilt, so they are a bit pricey. Also, older Unisaws used a repulsion/induction ‘bullet’ motor, while newer ones switched to TEFC. The newer motors won’t fit in the older cabinets without modification. You may also need to change/modify the starter on the saw to allow the use of the new motor. For 120v, you will be limited to a 1.5hp motor, possibly 2hp if you find one that will work on a 20A circuit.

I’d use the lack of a motor to significantly lower the price. That is of course dependent upon the condition and completeness of the saw. Without seeing it in person, it’s hard to tell if $300 is reasonable or not. If it was in great shape otherwise, you are looking at spending $600-$700 or more total to get a working machine. Used, complete Unisaws can be found frequently in that price range or less, so it might be better to just keep looking.

Cheers,
Brad

Thanks Brad the pics dont give an age but pics look like it is in great condition on the out side. I would think it would be under powered with that 1.5-2HP. What HP typically came from Delta on it?

Older ones with the bullet motor were typically either 1 or 1.5hp, although you could get smaller ones (nothing larger though). Newer saws with the TEFC motors were usually either 1.5hp or 3hp (single and three phase). IIRC, they also offered a 5hp option at some point. There are lots of 1.5hp Unisaws out there. I don’t believe they ever offered 2hp from the factory, but I’ve seen aftermarket replacements that size.

Cheers,
Brad

Bill,

Don’t know your level of mechanical skills. No motor means a lot of work on a used saw. There is a rebuild YouTube video on a delta unisaw. You might want to do a search with the model number to get some info to make the decision.

You say needs a new motor. As in, the old motor is present but not functional? Or motor is missing?

Grizzly has a 3 hp motor that will fit that saw (has the correct mount). Also a 5 hp. But it has a 7/8” shaft, so you have to get their 3 groove pulley, too, with the 7/8” bore. Price isn’t too bad. I went this route myself recently when my old (Delta) motor crapped out. No doubt fixable, but by the time the wiring problem would have been taken care of, and new capacitors, and new bearings, all at $70 per hour shop time, I was half way to a new motor.

Oh, I also got a new magnetic switch to go along with everything else.

You’ll like the Unisaw. A great machine.

Just went to Grizzleys site for the motor, saw there Hybrid, G0771 is on sale for $695, that may be the way to go, whada say?

Depends on what you will be doing? Not as heavy duty as the cabinet saw and more heavy duty than a contractors saw.

Haven’t used one. It would give you the 110 v. option that you need. Otherwise, DocSavage is correct.

$300 + 700 = 1000…...not such a great deal…got mine with unifence and 3hp for 800. Also guy showed me it worked before I layed down the cash. You don’t know what else is wrong….but seems parts are readily available. Good luck.

Doc, now I have a Delta 1HP basically a contractor saw with a fair fence/original fence, it serves me well with good blades I have. It is wide enough, I wish at times I had more front to rear table, but I do have an out feed table extension. The saw does not deserve the cost of a better fence to the tune of 300$+.
Right now I have more money then time in the shop, my moms care giver. So just shopping, I will wait for the right thing to come along and decide if I really need it. At this time I have no serious issues with the one I have.

It would be sacrilige to put a Grizzly motor in that Unisaw! The cheapest route would be to find the same size/phase motor that was in it on e-bay, which would just be a plug in deal. Another inexpensive route would be finding a nice 3 phase motor on e-bay and using a VFD. You could then sell the starter on the machine (which wouldn’t be needed) to recover some of the cost. You can find 3-phase unisaw motors on e-bay pretty cheap. If you are limited to 120v, anything up to 1.5hp can be used with a TECO FM50-101-c, which you can get for about $140 shipped. That would give you some huge advantages you could never get with a single phase machine.

Cheers,
Brad

Brad, I am not real familiar with 3 phase conversion from single phase, I always thought you needed a mechanical device for that, are you telling me what you posted will do that for me? Take me there in baby steps. Looked on Ebay lots of Emerson motors for the Unisaws and few originals, but dont give a hoot of info on there condition.
I am in uncharted waters here, and dont want to sink the ship. So guide me please.

A VFD will take single phase input and run a 3-phase motor, and it couldn’t be any easier. Two wires in + ground from your wall outlet, 3 wires + ground out to the 3-phase motor. Done. And a three phase motor is more robust, more efficient, and with the VFD you get all sorts of extra benefits (slow start, over-torquing, electronic braking, variable speed up to 2x times rated, overload protection, and much more).

Cheers,
Brad
