I bought an electric motor on a whim and have no idea what do with it now, any thoughts?

I bought a motor for $25 because I convinced myself that it was “too good to pass up” and new in box…I’m sure many of you have been there.

1/6 Horsepower AC Motor 115 volts 1140 rpm 5/8 keyed shaft

What would you do with it?

the catch all plan is to just keep it around until “need” to motorize something.

I could try to sell it but that’s much less fun. New the motor lists for 2-300

I’ve done that before, and it’s nice to have a spare, particularly if you have machinery that it could be installed on.

Lovely, open question that spurs the imagination. Glad you asked!

A few sugestions:
- Make an Apple grinder like I did
- Perhaps an Air raid siren
- Or a Box fan
- If the motor can be reversed to run as a genereator building a windmill could be fun – and the blades makes for a great ww project
1/6 horspower is not super much in the shop but it could probably easily run a disc sander, a slot morticer Festool-style or a small lathe. Or a smallish dust collector
With a worm drive reduction gear it could make for a garge-door opener or a crane or perhaps run the bed of a log sawmill or a slow speed wet grinder. It could power a motorcycle/moped/atv lift or a pump for the garden. Or 1000 other tings…

Let us know how it ends!

I had to chuckle at your post as I bought a 1 HP motor at the flea market because it was $15.00.
It laid around and mostly in the way, so I built a drum sander to fit the motor to … well the bottom line is that it cost a bit over $200 to use the $15.00 motor.

1/6th HP, 1140 RPM seems like an odd size … Hmmm, I’m drawing a blank here … Maybe buy a mandrel and make a …. thingey …

I have been think about making a 16 inch disc sander, a spare motor found on the cheap would do the trick, not sure about what HP or RPM I would need, but one can always change some pulley sizes and such to get the speed and torque needed.

I am not sure 1/6 HP is enough for a sander with more than a 6” disc. That motor is used for primarily air movers, cooling fans ans such. Sell it and get yourself a 3/4 to 1-1/2 hp motor for a solid 12” dia disc sander.

Or sell it and keep an eye out for a kaput washer or dryer. They typically have 1/2-HP motors. And it’ll have a pulley. Though, not always a V-pulley. If you score 2 motors of the same HP and RPMs, you could connect them to the load with a belt in triangular formation, and have double HP. Will that work? Anyone tried it?

1/6 hp is no where NEAR enough for a sanding disc. Here’s where I tried and found out I needed more power.

Not enough hp to do much.
With the right size impeller would move about 500 CFM for an air filter.
With belt reduction could drive a potter’s wheel.
Could run a scroll saw possibly or a small disk sander (under 6”)
With a bigger motor to run the drum, it could run the crank for an oscilating spindle sander or edge belt sander.
Could run feed rollers for a planer or drum sander with enough reduction.

Most useful thing would be to sell it and buy a bigger motor.

I have a 2hp motor for my 12” disc sander, where I used to work we had a 20” disc sander and it was 5hp. 1/6hp isn’t much, my air filter has a 1/4hp motor. Looking around my shop, I can’t find anything useful that could use that little power. It could be about right for a feed conveyor on a drum sander.
