People are using treadmill motors to replace motors and pulley belts in drill presses, lathes and other machines That makes it nice if you want to get rid of pulleys and belts to control the machine speed Changing speeds on a drill press becomes way easier and faster The speed of a DC treadmill motor can be controlled via a circuit board For good measure I added a tachometer so that I can tell what speed the lathe is running while I work. (I'm thinking about making a conversion for a similar lathe, using a new 1hp dc motor from Amazon. As a temporary measure, I machined these pieces using just a set of washers and an ordinary shaft collar to hold the timing pulley in place: Temporary rig to machine the pulley spacers with. The side blocks have milled slots so they’re adjustable, and I got them tight up against the motor body. Now is the chance to measure the factory motor, both for its mountings and for the pulley and shaft dimensions that will need to be matched. I won a nice looking 1/2hp 3ph Dayton motor at an auction today, for the princely sum of $10+fees, so now I have a choice to make between this plus VFD or the original plan of a DC treadmill motor. Check the specs to be sure they’re compatible with your motor. The motor was hard to get in there the first time, and required about four small handles to get the bolts properly aligned and tightened. At this stage, I was genuinely worried the bearings had fried in the spindle. Be sure to read their web articles too and you’ll learn a lot. Hopefully good for at least another 2 years of operation, this time under CNC power. Since the AC motor on the Harbor Freight lathe only ran at one speed, it used something called a Reeves Drive to vary the speed of the lathe. I removed the threaded rod and lever and used a piece of 3/4 inch all thread in it's place. When I got them home I started taking them apart. 2.50 HP treadmill motor for lathe, windmill, grinder or projects.

Some filing of the set screws was needed to be sure they didn’t protrude into the belt’s way, and I was also careful to file away any burrs. New, unused, with manual. 1. Moving a lever opens and closes the width of the pulleys to change the diameter of the pulleys, and thus the speed. Not sure I’ll ever take advantage of it. 1. $43.96 shipping. This was slightly touchy. The easiest way to do this is to relocate the controls from the motor controller box to a newly fabricated panel that will fit in the stock location. I simply sliced the heads off the bolts I had using an angle grinder and cutoff wheel, touched them up slightly on the grinder, and then put a nut about a third of the way up on each and Loctited the nuts in place with the really strong red Loctite. I already had a metal box laying around the shop so I decided to put it use. Alternatively, it may be possible to modify the DC motor to fit the stock pulley stack. Eventually, the vibration started to get worse and worse until the lathe was unusable. Then use a belt pulley arrangement to adjust the different speeds. You can see what it looks like (partially at least) down below. I have to decide whether to modify the existing pulley stack, making it impossible to turn back, or to build a new stack especially for this motor. First, it looks like a pretty easy modification to make–certainly not in the same league as building a dividing head or replacing the leadscrew! Most of these lathes get down close to 1:1 (usually 1:1.2) on their pulley arrangements. 2 years ago Has your config help up OK? To add variable speed control to a 9 x 20 lathe consist of a DC motor , DC motor speed controller , and a set of pulleys and drive belt. There are plenty of DC controllers available on eBay. 4.

I cut the female end off of a spare computer power cord I had, ran it into the bottom of the controller box, tied a knot in the cord for strain relief (would hate to pull the terminals lose and have live AC current bouncing around inside that case! Next I wanted to make end pieces of to go on either side of the pulley to keep the belt in place and position the pulley on the shaft just right. It is hooked up to a wood lathe. In case I ever need to put the AC Motor back, here are the connections…. $229.95. (Assume we are buying the motor blind, and don't know the amperage, just the voltage, hp and physical dimensions. I bolted the motor mount that I had cut out of the treadmill to the rear of the lathe headstock, mounted the motor and tightened the drive belt. Great instructable thank you for putting it together. part# 128957. use to replace controller on treadmills. Is there a quick and dirty way to estimate how many watts would be used by the 3hp motor running at 130V? The picture shows how to do the wiring. Share it with us! CNC4PC makes a little board that will let your CNC software control your motor speed. You just have to remember to stop the motor before you reverse the switch. Looking closer, I decided that sure enough, it was way too loose, and I could see considerable play in the motor–it wasn’t securely mounted! Second, there is a lot of bang for the buck. To complete this project we bought the following items off of Amazon. This modification requires the following steps: 1. I did a search on “(variable, controller, controler) motor” and bid on this one. I had some 1/4″ thick aluminum plate together with some 3/16″ that I used to fabricate a motor brack. Being able to change speed at the twist of the dial is a dream come true. I put these at 90 degrees to one another. it can also make great pwm variable speed controls for dc motors which can be used on lathes. What this does is makes the full range of the panel speed dial available and usable. I have a Harbor Freight 12 X 36 Wood Lathe. I couldn't believe my luck! 4000 seemed a bit much, so I scaled that back a bit too. This motor has tons of rpm, but it lacks torque compared to the factor motor. 90-180V 10A. I also bought a bridge rectifier to change the AC from the motor controller to DC. Only 1 left! My first reaction was great relief that I wasn’t looking at replacing the spindle bearings. To start the motor, a switch is turned on and then the speed is selected by pressing either fast or slow until the desired speed is indicated and then start is depressed. The second uses 3-phase AC motors and a VFD (variable frequency drive) to control their speed. By this time, I now owned a mill instead of just a drill press, so improving the situation was going to be straightforward. Never used a 3ph motor before. It’s fair to say the latter is closer to industry practice. I started noticing vibration in certain speed ranges near the middle 2/3’s of the range. There’s a lot to clear away to get at the motor mounts very easily…. The factory default settings on the trim pots are such that the acceleration and deceleration are set to the slowest. One motor was rated at 2.0 horsepower, and the other at 1.8 horsepower.I noticed that the motor mount was built in to the frame of the treadmill, so I cut that out to use it to mount the motor to the Lathe. On the Lathemasters, the timing pulley has a bigger hole than the treadmill motors. Coincidentally most Treadmills use a 80-260 VDC motor with a suitable HP rating and a PWM motor speed controller to allow the user to change the belt speed and keep a good constant speed and torque while running on it. Icon DC Treadmill Drive Motor 2.65HP Gold's Gym 480, wind turbine, lathe, gen. Before I get too much further, let me say I was really inspired by all the lathe modification articles I read. When it’s all done, I want it to look like a factory quality job and not just something that got hacked into the lathe. It's sturdy. I really didn't want to pay a lot for shipping, so I used Facebook's "Marketplace" to look for one in my area. I think such rocking is likely how the original motor mount got broken.

DC motors are also easy to find on eBay. These drives range from 1/100 Hp. I was connected. Aha, says I! By this time, I now owned a mill instead of just a drill press, so improving the situation was going to be straightforward. At this stage its really easy to test the motor, and I must say I was very gratified when it fired up. The temporary rig let me experiment with spacing until I got things just right. Well done, and cleverly executed. Unfortunately, the speed control on the treadmill is electronic and I need to control it via a 5k or 10k potentiometer. 55 I love this idea! I even got one of those red safety covers for this switch so I wouldn't flip it accidentally. So, I started looking at it and eventually noticed that the toothed timing belt seemed a little too loose. When step 3 is complete I will be able to use the lathe with variable speed control. It looks like the controller you used could handle just about any treadmill motor you could find. Certain configurations seemed to make the belt want to walk off the end. Note: Some controls have a fancy electronically braked version of this. A little research yielded a cheap solution -- a treadmill motor. Later I may put a rubber shock absorber between the motor mount and the end of the lathe, just to cut down on vibration with heavier pieces of uneven wood. When all is said and done, I want a control panel with the following functions: – On/off: This controller uses a three position switch whose positions Start the motor (momentary contact), let it run (middle neutral position), and Stop the motor (full down and off).
