I have had to bore out pulleys before to accommodate these odd dc motor drives, but never one as big as a step pulley. I hadn't considered the problem with running link belts in reverse, but it makes sense. 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. Also note the speed range on the motor youre looking at. Visual Explanations: https://www.youtube.com/watch?v=FSMGOP01ulw.

Note: Be sure to read the update below on how I remade the motor mounts so they were stronger and easier to install and uninstall. Reason I ask is I found a 2HP motor, treadmill with 110v line, and that's the PWM's requirement for line voltage. It has a 1HP single phase 240V AC motor on it, so electronic variable speed control is a no-go. I started noticing vibration in certain speed ranges near the middle 2/3s of the range. If you google images of 9" South Bend, you'll see what I mean. He is great. Step 1: Types of Treadmill Motors I have seen 3 types of motors.

Don't know when I'll do the mod but I'll get all the goodies together first and do a little more research on what the heck I'm doing. I dialed it up to 30 or 40 rpm at the minimum. Save my name, email, and website in this browser for the next time I comment. Different speeds were achieved by stopping the machine and changing the position of the belts on the different sized pulleys. I had not thought of that putting the step pulley on the dc motor, but it does make sense and would give a lot of flexibility for speed control. I took the electronics, wiring, and, of course, the motors. 9920 Painter Ave. Eurton Electric Co., Inc. 1.5 HP 3100 RPM. I couldn't believe my luck! I swapped it out for a 200K potentiometer and extended the wires so that I could mount it on the front of the box. This will allow you to adjust the speed of the motor by rotating the potentiometer. I unplugged the small red/black/white jumper wires between the boards. You can also see the mounting plates. We happened to have a treadmill that was broken that we used as donor components of the motor and control board, the rest of the required items were purchased.

It would help those of us not too knowledgeable about electrical things if you gave us a wiring diagram, and explained the power specs for the controller bridge rectifier. by LX Kid Tue Apr 28, 2015 8:47 am, Post If I had it to do a second time, I think I would make either the top or the bottom holes over sized to make the alignment less finicky to get started. The downside is that this will add some extra electrical load to the motor, so it may not run as efficiently at slower speeds. Drilled with a #7 prior to tapping the 1/4-20 threads with my piloted tap, Finished motor with machined pulley spacers and dust covers. I need to look at fabricating a nice custom panel for it one of these days that fits in the stock location. 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 may not display this or other websites correctly. I suspect it would be ok to remove fan blade entirely but monitor motor closely. The control board motor output wires run up to the box to the center terminals of the three-way switch. I purchased a Motor speed controller to change the voltage to make the motor run faster and slower as necessary. This was slightly touchy. I think such rocking is likely how the original motor mount got broken. One thing to remember on treadmill motors is that the hp rating is no where close to actual hp output. Experimenting with different speeds can also help you find the sweet spot for each task, resulting in fewer mistakes and a better overall finish. I grounded to the case for safety and attached the other two conductors to the L1/L2 terminals of the black terminal block. The first factor is the cost of the lathe. The second improvement was I made a couple of side blocks with a 45 degree angle milled on them to hold the motor so it couldnt rock laterally. Fast & Free shipping on many . The motor is only half the battle. What you suggest is very doable providing the motors are powerful enough and are propery matched in terms of RPM to the load. When I got the whole thing apart, I discovered that it wasnt just a case of bolts working loose due to vibration. The switch spec sheet is attached for reference. Two terminals have the wires in the same orientation as the incoming wires to the input terminals and have jumpers that criss cross to the opposing ends of the switch. 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. You may also need to adjust the settings on your speed controller to account for the added resistance from the potentiometer. Visual Explanations: https://www.youtube.com/watch?v=ZFVuJ0hwNnw&t=194s. Theres a lot to clear away to get at the motor mounts very easily. Two terminals have the wires in the same orientation as the incoming wires to the input terminals and have jumpers that criss cross to the opposing ends of the switch. 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 ran perfectly once I stuck a paint stick into the plastic key slot. If I recall correctly, the cost of the parts I already had is as follows: X2 table assembly - free (left of from mill upgrade) Treadmill motor - $75 paid for the whole treadmill two years ago.

Because no matter who you are, you deserve to experience the very best. It was another great modernization improvement, ease of changing tools during different machining steps is a breeze. Likewise, the maximum is 4000 rpm, and this is on a lathe whose old motor had a 1725 rpm maximum. #1. 7x12MiniLathe@groups.io | Converting 7x12 Lathe to Power from Treadmill Motor Note: groups.io will be down for maintenance on Monday, September 26th, starting at 9AM Pacific Time (4PM Monday September 26, 2022 UTC), for approximately one hour. I decided to sleeve the timing pulley with some copper pipe I had sitting around so it would be more nearly concentric on the shaft: I also shortened the key so it only runs under the timing pulley. Also, use proper personal protective equipment (PPE), including gloves, goggles, and a dust mask, when working with power tools. How cool is that? The control board has a seven connections you will need to make, three terminal connections that a 10,000 OHM rotary potentiometer is connected to. Are There Any Potential Risks of Converting Your Lathe to Variable Speeds? 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. Thanks Don and ninefinger for your replies. There are different techniques for you to get this done. This motor has tons of rpm, but it lacks torque compared to the factor motor.

Register today and take advantage of membership benefits. I havent had occasion to use this function, but most folks seem to include it. Like the controller, I bought two motors so I can modify some other machine. To me "line voltage" in house wall plug in! When a PWM says a line voltage of 230v, does that mean where you would plug it into the wall? Here is the assembly as removed from the treadmill, Leeson 1.62hp motor, plenty of power. Also note the speed range on the motor youre looking at. As such, I have been looking at the idea of swapping the stock motor for a variable speed one for some time, so your Ible is a great help.Then it's off to the drill press.THANKS. why does it do that to me? A variable frequency drive is essential for this project. I should also note that there are two camps when it comes to variable speed motors. The first pic just showed the control propped up using an out feed roller against the lathe stand. Southbend Lathe Power Crossfeed Conversion and other Ideas. "Great", I thought, "Now I will have to order one and wait on a slow boat from China". Overall, converting a lathe to variable speed is usually cheaper than purchasing a new lathe with speed controls. Where I work in Iowa, we've got an "845"Hp motor on a large air compressor. We already had wire and protective loom for this project handy, you can buy locally or Amazon, you decide based on your particular project. I was looking at KBMM-125 controller. Figure your max desired spindle rpm and divide it by 1.2 for a decent estimate of what maximum speed youll need from your motor.
