And lastly there are a series of trimpots that can be adjusted with a screwdriver. Tips, techniques, modification and use of these machines is topical. Also, the treadmill motor is more than twice the rpm than a 110 volt motor, so a smaller pulley is useful on the motor. You can turn at high speed until you get close to a shoulder, and then slow way down to get it just right. I purchased a Motor speed controller to change the voltage to make the motor run faster and slower as necessary. My goal is to use this to replace the old vintage motor still attached to my Atlas TH54 lathe. I don't think your going to find that in any treadmill motor. We are getting less than 20,000 hours out of the bearings on that motor before they start to fail - a fraction of the life we should be getting. Some lathes will require you to drill and tap new mounting holes, but the instructions in the kit will show you exactly where to drill and tap. 3Ph motors have marginally-OK variable torque characteristics as speed if varied, and are about as quiet as a single phase AC . Do some research on that front before deciding. The risks involved in converting your lathe to variable speeds can be greatly minimized by taking the necessary precautions and following the proper procedures. I'm not familiar with either the treadmill controller or the the e-bike but speed/load regulation is a concern - if you set the lathe for a speed and then apply a cutting load, how does it handle that? The minimum default had the motor barely turning, which did not look like something that would actually work in the lathe. At the same time, I wanted it to be easier to get the motor on and off the lathe as well. Many drill presses, cplishers, small lathes, etc have been converted to DC treadmill motors but the more successful conversions required some carefully made choices. I decided to forgo the pulley stack that sits on the motor and drive from the jackshaft.

Those failures are due to the way the manufacturer treated that poor motor during the design - just to get the desired performance at a lower rated Hp. Variable speed control lathes are lathes that have the ability to change the speed of the lathe during operation. The link belt is easy to adjust size as necessary and it also does not hold a set like regular v-belts which cause machine vibration and chatter in small lathes. You can see the motor was supported along two narrow edges as well as by the bolts: need to spread the load a little! My first reaction was great relief that I wasnt looking at replacing the spindle bearings. Still think I will work on a shroud to keep the dust away from the motor, i tried my dust collector around the lathe, doesnt work!! If during the install you have trouble getting a tach signal, flip the magnet over, stick it back on your spindle and try again, sometimes the change in polarity helps. The maximum current on the motor rating plate will give you full power. owner informed me that the motor running the treadmill was a $300 motor. Well.. Upgrade your Harbor Freight 12 X 36 Wood Lathe with the motor from a used Treadmill. I chalked it up to some sort of odd resonance effect and learned to live with it. Another risk is damaging the gears inside the lathe. Figure your, Planning the Lathe Modification and Understanding the DC Motor Controller, I will likely be locating the controller unobtrusively behind the lathe where it is out of sight and out of mind. First, unscrew the mounting bolts that hold the old motor in place. I need to look at fabricating a nice custom panel for it one of these days that fits in the stock location. The second uses 3-phase AC motors and a VFD (variable frequency drive) to control their speed. Reverse: A switch to reverse the contacts so the motor runs in reverse. This way I can use the lathe to machine the pulley to fit the motor. ix. Certain configurations seemed to make the belt want to walk off the end. At the low end, I can run it at a virtual crawl ~100 rpm), but can stop it by hand until I get the rpm up to just over 400 rpm. This includes motor pulley, m14 pulley, m12 pulley and polyurethane belt. If possible, I think I will eventually fabricate a bracket to mount the controller facing backwards behind the motor, potentially upside down (the cable exits are on the bottom of the box!). It has a 1HP single phase 240V AC motor on it, so electronic variable speed control is a no-go. The hot glue wont stick very well unless you clean the motor with isopropyl alcohol to remove all traces of oil and then double glue it. True Treadmill 2.5 hp DC Pacific Scientific 450 500 Motor Lathe Dark Grey USA . Spindle bearings - $96.

Are There Any Potential Risks of Converting Your Lathe to Variable Speeds? I also fiddled with the minimum and maximum speeds. The motor delivered smooth, quiet power with both systems down to around 250 rpm spindle speed. Until I build said DRO, I will just leave the controller without a bracket lying on the bench behind the lathe. I was looking at KBMM-125 controller. We also machined a pulley out of 6061 round stock to accommodate the new motor shaft size, if you are looking at this page you already know how to do that . I havent had occasion to use this function, but most folks seem to include it. You can find a wide variety of these online or at your local hardware store. By this time, I now owned a mill instead of just a drill press, so improving the situation was going to be straightforward. This conversion is absolutely awesome and highly recommended and should have been done by us a long time ago. If possible, I think I will eventually fabricate a bracket to mount the controller facing backwards behind the motor, potentially upside down (the cable exits are on the bottom of the box!). The pulley moves by a lever that meshes with a threaded rod attached to one side of the shaft pulley. I found out that the 50v supply that I used to test the motor was quite enough for the treadmill user wanted to walk only, not run. The switch spec sheet is attached for reference. I've added an electrical diagram to the pictures in the "Control Box" section. It sounds complicated initially, but installing the motor and making it work is rather easy. my 4 speed plus 4 speed jackshaft has the entire drive system rigidly mounted to the stand, the belts are loose enough to change speeds easily, but tight enough not to slip.

Treadmill motor with KBIC drive, not vfd, but you must leave the pulleys and belts to allow the motor to run at enough speed to provide the horsepower needed for slow speed deep cuts and drilling operations. Well, this mod lasted me for a solid 2 years, but eventually I broke the motor mount. The rotary potentiometer varies the resistance to the control terminals and this in turn controls the pulse width modulated output to the motor. You are using an out of date browser. "Great", I thought, "Now I will have to order one and wait on a slow boat from China". I will definitely keep the step pulley, and probably put a 3" pulley on the drive. Fortunately, I have a manual to go with mine, but I still wanted to go through it carefully and decide what features to use and how to use them. Once the belt is removed, you can begin working on the conversion. Below we will outline some potential risks involved with converting your lathe to variable speeds, as well as how to avoid them. What Will a 3000 Watt Inverter Generator Run? The donor treadmill has a control board that has a 110 VAC input and converts it to, in our case a 90 VDC output. For slow speeds/ back gear the lathe uses a toothed belt of 1.5mm pitch. It's also very fast at 4900rpm your old motor was 1440, other that it should work OK. Black is not a colour ! Different speeds were achieved by stopping the machine and changing the position of the belts on the different sized pulleys. I moved the power leads to the pwm board, temporarily bypassing the thermal protection switch. That's much easier for me than trying to figure it out from the pictures. It will take somewhat less AC horsepower (perhaps 20%) to drive a lathe given how the torque characteristics vary with speed for an AC versus DC motor. "But", I hear you say, "I thought you said it had to be DC voltage?" Lets review the internal connections on the DC-2. 37129558 supply of ventilation fan motor ( foot mounted induction . Can You Build Your Own Lathe? Share it with us! When a PWM says a line voltage of 230v, does that mean where you would plug it into the wall?
