Man, I need some help. I am looking for an electric motor that can produce high RPM's. Needs to be at least a 1 HP, but I would go bigger no doubt if the price was near.

This is the closest thing I have found. I highly doubt I have looked at enough websites to find the right deal, and I can't write a book on electric motors. This one is 1.5HP - 3600 RPM. How high do these things go in RPM, because that is what I need.

need some more information for your application-what frame/mounting spec, what voltage you're working with, direct, chain, or belt driven, how you're controlling it, etc. most off the shelf motors are 1800 or 3600 rpm, to get the speed you want, the drive set-up may need some work rather than trying to get motor speed higher. you can get a higher speed motor, but it will probably be a special order and cost more.
 
Where did you find the belt sander attachment? Does the Delta motor not have enough ass to keep up? Have you looked into a square wheel 2x72 belt grinder like a Wilton? I've got one and love it to death. Variable speed, tons of torque, multiple attachments, and belt changes take about 30 seconds.

There are literal hundreds of designs and plans online to build your own legit belt grinder, the majority with a 72" belt. Once you get multiple different contact wheels and platens it will make that jet grinder look like a joke. That being said, there is no "cheap" way to even diy an entire grinder. Your best bet since you have three phase is to keep an eye on eBay and clist for a cheap used burr king.
 
you might want to take a look at those flap wheels and check the RPM rating, over speed one and it'll come apart quite spectacularly, possibly causing injury or worse.

had a co-worker that used a the wrong speed cut off wheel on his die grinder, cost him a testicle ( yes really ) and a lot of time off work when the disc fragged

That's essentially what we have, only ours is a DC drive, variable speed. I think we spent a grand on it, and it came with several platens, wheels, and rests. I named it "El Deburrage" and we use it daily. With a good belt, it'll remove metal quick-like. With a scotch-Brite belt, we've polished over 1000' of stainless handrail. With small contact wheels, you can cope tube all day. It's pretty much industry standard for knife makers and some fab shops. If you can find one for a reasonable price, snatch it up. You will not regret it. That Trick Tools attachment is neat, but a good square wheel will put it to shame.
 
just get a good abrasive notcher, they are super fast and you can deburr all at the same time and don't have to change to another tool to do that. Its quick and easy.
