2.25 HP motor... what to do?
 

So I happend to "accidentally" carefully extract the motor and Its supporting electrical equipment from my moms treadmill. It is rated for 2.25 HP (1.3 continuous) and though it doesn't say, from reasurching I have deduced its free speed to be about 6,500-7,000rpm (I will measure this empirically soon). 95vdc 18A. What should I do with it?

Options:
Put it back in
Sell it on eBay
Build something

The whole 95VDC doesn't make it super easy to use.

The treadmill must have the appropriate converter with it.

Hasn't she noticed that the walking takes a bit more effort?

Build a boat motor for the upcoming water game.

90 volt variable speed DC drives are common. Sort of the standard voltage for industrial DC drive. Comes from the supply voltage being 110 AC. (At least in the states) The 18 amps is at rated power which will be at some speed between free speed & stall.

Lots of people use motors out of tread mills for mini lathes & tools like that.

Hide it in a CIM casing and try to get it through inspection next year.

The motor has a controller that inputs 120VAC, 12V pwm, and outputs the 95volts. I think the best option is to see what the pwm the control panel sends to the controller looks like and replicate it.

I ended up throwing the treadmill motor I had onto the scrap trailer....

Well here's a little info on it:

It woulddd be fun to put on a GoKart :D
95v at 18amps is 1710 watts which is like almost 3HP...

But I am a bit biased.

That is some loose chain! Try using a half-link or 3 :p

Tensioners were built in soon afterwards. That chain was way to loose lol, i was skipping teeth when flooring it.

Going to Gt2 timing belt soon.

Re: 2.25 HP motor... what to do?
 

Sell it on eBay, there are indeed many folks looking for exactly a motor like that so they can have a variable-speed lathe or mill. It's worth quite a few dollars.

After returning to this thread I now realized a very good question...

WHY/HOW COULD YOU TAKE OUT THE MOTOR FROM THE TREADMILL?

Sorry for the caps but I find it necessary.
