This may be a bit off topic, but I would guess it is applicable for someone wanting to re-motor their lathe.
Have one of those 80s Taiwanese drill presses (Cummins Mack).? Motor HP isn't listed but it's probably 1/2 or 3/4HP.? 100vac single phase.
?
Kind of sick of changing belts and thought one of those variable speed motor conversions would be helpful.? I read a lot about how inexpensive these are, but I'm just not seeing it.
?
I probably have 10 motors lying around the shop, all 110VAC single phase of various sizes and RPMs.? Looked around for something in the 3/4-1hp range in a 3phase motor on Craigslist, Marketplace, ebay, surplus dealers - they don't seem cheap to me.? To get something in the right RPM range (~1700) and standard voltage is at least $100 if not closer to $200.? Add another $100-200 for a VFD and that's not my definition of inexpensive.? New motors are double that.
?
Read about using a treadmill motor, but word seems to have gotten around about those.? They're in the same price range as the 3phase motors, although the controllers seem cheaper.? Buying a couple of random treadmills to hope and get the right size motor that's useable seems like a big PITA and here in rural America, getting rid of the rest of the treadmill without the motor isn't exactly easy or cheap.
Am I looking at the wrong things, or am I just a cheapskate?? Maybe both.
I've read it's possible to use a VFD on a single phase motor by bypassing the start capacitor using a start switch to energize it.? Having trouble finding good info on what VFD to use.? I don't really think I need the drill press to reverse, which is one of the downsides of single phase.? Would this be a solution to use the original motor or one of the spares I have lying around?

You might want to consider using a 110 volt?.
I use them on my 8520 mill and on my 16" Delta band saw. I also had one on 12x36 lathe.
There are other brushless? explore.

Dealers Electric sells motor VFD packages but rite now looks like
teh cheaper ones are only @ 3rd hp .
When I look for treadmills I ask for the model # of the treadmill
, than a google tells me what motor controller & motor the
unit has , If it's the right controller that I'm lookin for &
tell them that I will take it . My issue is that due to my current
disability I have to either bring someone with me or tall them I
will need help loading .

Was also thinking it wouldn't be a terrible idea to get a foot pedal speed controller and rig that up as an alternate way to control the machine.? Would be kind of cool to be able to vary the speed without having to reach up to a knob.

I agree with others here.
I would look at brushless with the correct control.?
The lathe right has a DC motor but the dat I need new one I will look at brushless as a replacement.??
Doing other type is great if look to tinker with motors.
Myself I just get replacement and get back to running my tools and only replace as need.

The other part is if replacing a 1725 rpm with new motors turning 6,000 rpm.
You look at doing new belting too.?
There keeping the cost of motors down by turning the motor at high rpm. Great for new equipment saves us money.??

Things would probably be different if I actually had to buy a treadmill ;-)
Around here (VA beach, VA) they frequently show up at Curb-Mart on trash pick up day. In addition to the motor & controller, there's usually quite a bit of usable steel tubing & other hardware. The seat & seat post from a discarded exercise bike makes the beginning of a nice shop seat for bench work.

If ya haven't salvaged one before? aside from the motor &
motor controller make sure ya keep the choke ( transformer lookin

Went down the rabbit hole on these sewing machine motors.
I'm liking them.
I found some sites that show how to add a potentiometer to create a speed control dial to replace the hall effect sensor used in the treadle control.? Some conflicting info, but I think I have a couple of combinations of pots and resistors that should work - it's pushing the limits of my electronic competence.
Also found a couple of ways around the clunky reverse control, not that I expect to need it on the drill press, but if I can get the RPMs down low enough, it might be nice to have it as an option for tapping, although I've always preferred being able to feel with a hand tap, even if chucked in the drill press to hold vertical.? Since the motor is three-phase, just swapping two phases and one associated hall effect sensor in the motor will reverse, and there are inexpensive 4-pole drum switches on ebay that are rated to the voltage/current without spending too much cash.? I even found an emergency switch with three poles that would cut the three phases to the motor.
Think I'm going to pick one up in a few weeks and give it a try.? May get another for the 7x lathe - I'm guessing I could sell the original controller board and motor on ebay to close to what the sewing machine motor would cost and gain a little extra power and not have to worry about the control board losing it's smoke sometime down the road.

If the motor doesn't get to the low speeds yer after maybe ya can
get them if ya keep the multi pulley setup available for threading
. Folks have been using these Consew motors for years on the
lathes & other shop machines & I can't say I have ever
heard a bad review on them for this purpose , One guy had a issue
but the vendor made it right & sent him a new motor , but
that's about it for bad press that I have seen .

I have a 3/4 hp sewing machine motor on my Logan 820. (10 x 24)
It is fantastic. Infinite speed control, small, 10 years ago it was $105 and was complete.
I rigged a rod and wingnut on the foot control.
It also has a speed selector and reverse.
Between the Logans gears and its speed control, I can get lots of torque or speed or both.
Sometimes a motor that can stall is a feature, sometimes it's not.
You can choose.
Sewing machines come in all sizes, like lathes.
EDIT, this looks like the motor I have, but not the same vendor.

You can get those sewing machine motors on Amazon for quite a bit
less than that ebay listing.
(Note: Not Prime... shipping is $25 on the one listed but you can
find them for less shipping - they always land around $100 total
though)
I have one now that I am fitting on one of my X2 mini-mills - if
it works as well as I expect the 2nd mill will get one too :)
I don't know others, but the one I linked uses standard Molex
5557 (Computer PCIe power) connectors if you want to make custom
wiring or use attachments not included in the kit.
Earlier in this thread someone mentioned the RPM ratings of this
motor and claimed the higher RPM is due to losing power at lower
RPM, implying these are not a good choice for many applications -
that is not true with these motors. These are basically 3-phase
motors and the way they change speed is *not* by changing/pulsing
voltage. These phase-shift to change speed so that you can keep
almost constant torque independent of rotational speed.
Just my $0.02 ;)

The Consew motor off ebay is a sewing machine motor. In Fact unless you are a certified?sewing machine repair shop there is no factory support. The brushless DC motor is essentially a three phase motor. I have thought about switching it for reverse as the factory?method is a pain . A switch would be great.. As I said I have one on my Clausing 8520 mill and my 16" bandsaw. I had one on my 12x36 lathe for a couple of years. Something started happening on the lathe ( I was getting error codes) so now I have a direct drive servo motor on the spindle.
I still have two of the motors. I might put one on my mini lathe and the other possible on a grinder.
With the pot for speed control I was able to get 5 rpm.
When wiring the pot you do not need any resistors at least I did not use anything but the pot.
If you want to discuss this outside the Lathe forum you can join the AtomicELS forum?it is my group and you can discuss any shop project.

these are way different motors than yer average sewing machine
motors . The ones in this thread are servo motors & probably
2-3 times the size of a standard sewing machine motor . I've
seen these motors up to 1 hp they may have some that go higher ?
here's a tube of a guy that put one on his mini lathe , it's not
the best vid , but it's the first one that poped up .
