What are some possible motors I can use on an x2 mill?

[chronic]

Hello, I've been trying to search for this but I haven't come up with much. I may not be searching for the right info though.

I have an x2 and I've been curious what the largest motor I can use with the stock electronics is? Have many people tried different motors? I realize it would be a shot in the dark finding something that mounted up semi easily.

350watts seems good enough, but more power wouldn't be a horrible thing. However speed would be a nice thing to increase too.
So I have been thinking maybe I could install a 3/4-1hp motor and gear the mill for some more speed while maintaining similar torque.

Thanks.

Gut feeling: A treadmill motor with the controller that was on the treadmill. Free and effective. Never tried it. I have one sitting in wait

Alright, cool that gives me some place to start looking into. I had read a little something on that.

Not too many other people have played with different motors though? I see the one guy is trying a 3hp motor in his x1, I was going to post in there but I dont want to hijack anyones thread.

So, any more ideas are welcome!
I'm a machinist by trade, not too high on the scale of electronics. Only electronics I consider my self well read in are brushless rc systems.

Well, you could also scrap the original drive and replace it with a VFD and a 3-phase motor. Variable speed, smoother operating motor, and some other spiffy features.

I got a .5 and .75hp 3ph motor for a song, the bulk of the cost is a VFD and the time spent figuring it out. My drill press will be the guinea pig for conversion, then the mill or lathe will get it next.

You can Hijack my thread were all here for one another.
I was going to use a tread mill motor but here is the problem I seen.
They have dual shafts with a fan at one end.
What happens on a hot summer day when your putting in heavy work and you over heat the motor . All that time and money went out the window.
You can figure out another way to cool the motor ,
IE a large PC fan.

I didnt go with a tread mill motor for this reason , There also only ment to turn one way.
In a little bit ill upload a picture of one of the brushes and show you why.
Between the fan and the brushes there not a good candidate.
Ide get the correct motor for the job. Ive looked at plenty if you would like I can show you all the ones I thought were good for the conversion.

Maybe like This PC fan, it really pulls the air through the motor. And how about Water cooling, I've run the he** out of this motor and it's still going like new. I looked all over for a replacement motor too and I never found one better suited than the original X2 one.

Just some ideas.

Thanks for the ideas.

Your water cooling set up is very cool! I like that. I dont run mine too hard too often, I'll use it all day some weekends. But it never seems to get that warm. Guess I gotta step it up haha.

Not sure on the terminology without looking, but I think the term is "reverse." If the treadmill motor says reverse on it, it has standard brushes for both directions and can be reversed safely.

The problem with turning some treadmill motors are that some of the brushes have a angle on them.
That why they are suppose to go in one direction.They will go in both but the bush will burn out quickly.
I snapped a pic but it came out horrible.

That's interesting.

Well something I neglected to say, another reason I was scouting out other motor options is because my stock motor has a defect.

It took a while to figure out. Its like every revolution the motor lurchs, and when the mill is cold. This will draw a bunch of power in high gear and trip the overload circuit.
After some investigating, I realized the motors commutator? The bundle of brass pads soldered to the windings the brushes make contact with, is that right?

Well it was installed off center. I can get it warrantied, but It does run fine when its warm. And I use it so much I dont want to be down my mill. So I've been thinking about buying another motor (stock or not) then sending this one off for warranty.

I just didn't realize I may need to look into new controllers for different brushed motors, and being such a noob with this stuff. Maybe I should stick with the stock 350w motor and just machine my self parts for a two speed belt conversion to get my additional rpms for those 1/16" end mills.

Well you can get a new one from LMS while the old ones being fixed.

Probably takes ages to get the old one back, but then you could sell it on Ebay or here.

That would be the easiest way.
Grizzly sells the motor cheaper though chances are it will be back ordered,
but it's worth a shot.
