Two years ago you inspired me to convert two wood lathes to variable speed, Daze. Then you helped fine tune them with the proper gearing, a cooling fan, a quick start bypass switch (disabled safe start), a tachometer and a reverse switch. The speed control has made a huge difference in tooling a fine wood finish instead of using 80 grit sandpaper. I rarely touched the four gang pulleys before knowing you and now speed changes are made 10-20 times each project. If you come to east coast Canada (New Brunswick), Daze, you have a place to stay. Thanks for sharing your knowledge. Salute! 👍👍

These are all great lessons and you offer the correct solution for this application (machine power conversion). Almost any application really. There is another solution for some applications, although cooling and gearing is applicable to every electric motor application. Specifically, when electric motors are used as traction motors which will require the motor to run from 0 RPM through the max RPM, using two of the smaller motors might be a better option. In the early 2000's my tiny business built high performance stand up scooters before it became the thing it has now become. We had limited resources to source our products from. To keep costs down it made sense to use the standard Chinese scooter parts, but simply installing a 300 Amp (golf cart) controller would ignite the brush housing in the first ten feet. Likewise, any attempt to modify existing controllers resulted in MOSFET fires. Now you know why we call them Metal Oxide Smoke & Fire Emitting Transistors. What did work in this application was to run 2 of the best cheap China motors available which were rated at 800 watts. Since the entire vehicle and rider only weighed 300lbs, we could dump stupid amounts of current into two motors for just a few seconds and get away with it. All we were really trying to do was teach the gasoline scooter people a lesson about electricity in a short drag race. It worked.

Have you messed around with any 3 phase AC drive motors? You can find them in almost all Life Fitness commercial treadmills. Matrix treadmills probably have the most powerful commonly seen treadmill motor(made by Johnson Controls) out for the past ten years. Cybex is owned by Life Fitness so their stuff is cross compatible sometimes. And Precor and Startrac commercial treadmills also have some of the most powerful motors out there. Most are AC motors though… there are two Precor treadmill models called the 932i or 946i that is about 20 years old now. If you come across one of those, they have Massive DC drive motors made by Leeson. Very rare to see one of those motors ever fail and the bearings are easy to service/replace.

Take the specs on the original AC motor and calculate the torque. This is a good starting number but more is better so from there you can increase torque with gearing assuming the new motor has more RPM

So uh question for the expert in the field, I just salvaged a commercial 220 volt treadmill and pulled a 3phase motor, I can tell that the VFD is on the control board but am helpless as far as figuring out what to do to get it turning.

1. I'm with you on motor cooling: kzread.info/dash/bejne/iYaoo9Sop5W7fbg.html 2. An advantage of running remote cooling through a duct or hose is that it seals up the brush end of the motor, which really does not like dirt or swarf getting into it 3. You are correct about the tradeoff between low torque/high RPM and high torque/low RPM - and you are quite right that the motor manufacturers overstate the HP numbers on these motors. However, higher speeds have a use all their own, especially on cutting tools like lathes and mills. Being able to drive the tool faster opens up the door to carbide tooling (which likes high SFM) which can often be more productive than a speed-limited, higher torque motor. Your typical hobby lathe 100mm chuck is frequently rated for 3500-4500 RPM, and spinning it that fast (with the commiserate feed speed) can generate a much higher MRR than a lower speed, even if the lower speed can take a heavier depth of cut. Within limits, RPM is king!

@dazecars

8 ай бұрын

Good info I appreciate you sharing it. The one thing I caution people when it comes to hobby lathes and RPM speed is to do one of two things. Either maintain the OEM speed max, in other words don't drive the spindle faster than its max speed from the factory OR do your due diligence and make sure the bearings are up to the task. This involves getting the bearing part numbers and then trying to find the speed specs. Unless the manufacturer is clearly marked on it you can only get a range. If I was wanting to overdrive my spindle I would simply replace the bearings so I was absolutely sure the bearings were up to the speeds I planned on running it at. Lastly the further you go from the original max speed the the higher the risk of the structural integrity of the spindle not being up to the task especially if you have upgraded to a bigger chuck with more mass. I am sure a typical import spindle with correctly rated bearings can handle quite a bit more speed but the faster you go the more cautious a person needs to be.

The other reason to gear them down aside from torque is cooling. A DC motor turning at 100 rpm isn't going to last too well. I've used these motors a lot but find they tend to vibrate too much, especially without the flywheel. I guess in things like treadmills they're built to a price.

At 1:05 and later you say the green wire is for electrical short circuit protection. That is just 1 aspect of safety that it can provide. It is also for static electric charge dissipation. A tread mill is a great Van de Graaff generator and could kill you with static electric charge buildup suddenly discharging through your body! I know you are not building tread mills in this video presentation, but talking about treadmill repair or repurposing requires additional non-traditional safety concerns to be considered. Be safe! Good luck! Wear safety glasses!
