I just picked up a new Delta table saw. It comes wired for 110V but says it can be re-wired to run off of 220V. I could fairly easily run a 220V wire in my garage. What are the advantages of doing this? Would it be worthwhile?
Thanks,
Ian

If you already have 220, maybe - it might be a tad stronger. If not, I don't think it's worth the expense of running 220 wire and getting couplers just to do it.
If you have aspirations of getting all bigger tools, though, you might end up doing it, anyway, and it's your choice.

A motor running at 220V will last slightly longer than one wired for 110V. Less stress when starting up on the brushes & stator.
At least, that's what I was taught.

Agree - if you already had 220V in your garage, I would use 220V. If you only have 110V, then I would wire it to use 110V.

I think the best advandtage of this is for future machinery purchases. It's not going to save you any money or run your motor that much cooler. It does allow you to have other options the next time you want to buy a different tool or upgrade what you have.
That said. If you run 220, I would do it right with a new sub panel and proper wire size to handle said sub panel.

I thought induction motors don't have brushes? Someone correct me if I'm wrong?

induction motors have no brushes You are quite correct
220 v power band does not deteriorate as quickly as 110v but there are a ton of qualifiers.
Add that the sparkies don't like the idea that theory and practical use are at odds and it creates lots of spirited disagreement..

220v tends to have lower voltage loss and better amperage flow for peak moments, so you might see faster startup and faster recovery from bogging. I converted from 110v to 220v and am glad I did. If you don't have 220v, and you don't have any issues whatsoever with your current 110v circuit, you might not want to bother unless you feel ambitious and can do it cheaply.

Sometimes the reason you hear that 220 is better is because many folks bring home a tool and plug it into an existing 110 outlet. That outlet may be one of several on the same run of a 15 amp circuit. Then, they put a dedicated 220 circuit in and it seems like 220 is a power booster. A dedicated, 20 amp circuit will make about the same amount of performance difference.
