Re: Variable speed motors
Most of the ones you¡¯ll find will have a 100v-ish DC brushed motor rated for about 0.5 ¨C 1HP, which is as good as or better than what our 7x12 lathe have, especially the older ones. Very similar

Re: Variable speed motors
I see why Treadmill motors are popular. On trash day you go down the street and pickup for free Treadmills. All you need to do is remove a new motor. Dave

Re: Variable speed motors
So I'm guessin that you probably have a MC-40 up to a MC-60 motor control board ? These aren't the best TM controller to use , though folks like then because all ya need is a pot to make them work .

Re: Variable speed motors
Thanks WAM, possibly the foot speed control I swapped out with a 20k pot was a photocell and vane not the hall effect and magnet. I did not do anything with the pot other than mounting it on my lathe
