Variable Speed Electric Motor / Voltage Regulator

[wesinls]

Anyone have experience with getting a large electric motor to work with a voltage regulator? I'm trying to find something that lets me throttle down the speed on this motor...i purchased a cheap one on Amazon to prove it would work, which it does, but it's cheap and not rated for enough amps. I need something a bit more industrial...MC Master has them (i think) but they are $$.
FWIW it's for a horse walker...I can go down the path of different pulleys, but that might be more $ and or more complicated to figure out, IDK. Long story as to why it's moving too fast after being "fixed".

It's running on 115 volt, 13 amps- as shown in the pic.

I think you want a variable frequency drive or VFD.

 

[wesinls]

ive looked at those too, but most seem to be 3 phase to single phase conversion -which I don't need?

Check the amp draw they way you have it set up now. It's probably not drawing 13a considering it is doing minimal work.

How about a router speed controller?

Rockler Router Speed Control

Provides the right speed to match the router bit and application.

That was what I tried - albeit a cheaper one...it was working . slowed it down, but wasn't slow smooth speed, and then tripped via its built in overload protection after a few seconds

Have a picture of the whole tag?

There is a reason why they use pulleys to control speed

Best option is get a 3 phase motor and get the single phase to 3 phase VFD. Its difficult to vary speed on single phase. I plan to get a 3 phase motor for my mill and get the conversion vfd.

Here is the setup - time to start looking for a pully i guess...what type of puller would I use to remove it? (after removing the clip) - looks like a normal automotive pulley remover will work

 

[Kraut_n_Rice]

Probably has a set screw too. Then a 2/3 jaw puller. Maybe some heat...

Or a higher ratio 3rd member in that diff. LOL

lol - ya, long story but the original failed and my wife had someone "fix" it with a new rear-end...gear ratio way off now.

I doubt you'll find a pulley much smaller than what's on there tho.

I need it bigger to slow it down...fingers crossed I can find something.

Check Johnstone supply or McMaster carr

No, you would need to go bigger on the big pulley(s), and smaller on the small ones to slow it down. You need to make the numerical ratio higher to slow it down.

So weird as my brain won't let me see that as being correct, but you're right, ty.

Adjustable Drive Pulley (Sheaves) - HVAC School

Before the fighting starts about term definitions, let's just settle on using “adjustable drive pulley” and “sheave” interchangeably to describe the belt-driven power transmission device shown above. Second, for the newer tech, you shouldn't be altering these sheaves so that the belt rides lower...

How much more are you trying to slow it? A bunch, like half? Or 10%..

Are the horses trotting and you want them to walk?

 

[wesinls]

Prob about 50% or more...it's scary how fast it is now. We havent even put the horses on it yet....maybe the VFD is the better route? I only have 120v tho.

Something like this?
