 Bought an odd looking electric motor at a yard sale i had never seen before. Someone had mounted a wire wheel on it with one of those cheap 1/2 in. hardware store mandrels.

Tag stated "Lamb Electric, kent Ohio, and "Formaly" Black and Decker Elec. Co.

Then i noticed -----RPM-9000 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 115Volts DC

No wonder people get hurt!!!

that sounds like an aircraft electric motor.  they use high volt dc current but more like 400 volts and higher

Rob , i googled the manufacturer, they are still in business, and appear to build vacumn and air pushing equipment. So i'm presuming this motor came off some type of industrial vacumn machine. The motor is heavy cast and a bit smaller in OD than a standard frame 1/2 hp motor.
Only paid a buck for it, the wire wheel is worth that, just an interesting shelf collectible.

Amazing that the 1/2 inch dia mandrel never broke off, as the wire wheel stuck out about 4 inches, and must have had severe balance issues at that RPM , and the wires appear to be all still in the wheel.

Scarey to say the least!!!!!!!!!!!!!!! Lol

If it's DC, you won't be running it at home.

 If you have a DC motor drive you will. I converted my sewing machine to a DC motor, as well as the feed on my thickness sander. The main advantage is that DC motors will give you variable speed, as well as low RPM torque.

 dc variable drives are ancient technology by todays standards, too dangerous and expensive.  i have a few machines at work with variable frequency ac drives.  sewing machine hemi?  i have some pants that need fixing, you need a few extra bucks?

 Dc drives are still used in a lot of place's that the Ac drives wont work .Ac has just become more popular because  of newer technology makes it the cheaper option similar to modern cars once you are able to close the loop and provide feedback for correction with a off the shelf item with fairly solid repeatability the more expensive method falls by the wayside. the same go's for what we had to use servo control on a few years ago can now be done proportionally. I really don't understand the dangerous part as the most common control circuit's are all low voltage dc .also dc doesn't have the inrush draw as ac dose . Once into the higher amperage there is no preferred way to fry as far as I know

Spinning a motor at 9k isnt a problem . spinning a wheel rated at 1.5k at 9k is. I dont think you can blame the wheel or the motor for this. I guess you could but neather would care. Maybe this is the reason most men are afraid of the washing machine. makes you want to clench when the spin cycle hits 18k.

My brother's been researching our family tree. We knew that my grandfather had been a Sawyer at one time, cutting huge old growth trees to size with a 5 ft. diameter saw blade run off his model T rear axle. Just heard from an old cousin of my Dad's that my grandfather and his brother-in-law were running the blade a little too fast one day. These blades had a huge extremely heavy cast iron flywheel attached to keep the blade from slowing the car engine down and this flywheel blew apart that day. They found one piece of it at the road which was at least 150 feet away from the saw and another piece a couple of hundred feet back in the woods. The piece at the road was saved and my brother now has it - it weighs over 10 pounds! Imagine if that had hit someone.
