This totally worked for me. I went with the 120v speed controller because I don't need 220, and it works great. I spent around $30 because I didn't want to wait, but I could have spent much less if I was patient. I also got 2 bridge rectifiers and 2 potientiometers for that price, so I have backups. Everything came from Amazon. Thanks!!

Caution: a brushed a/c motor such as in a drill is intended to be variable speed. An induction motor such as the band saw example is dependent on the 60 hz frequency for it's speed. Reducing the voltage to an induction motor lowers it's torque but not it's speed. Brushed motors using this setup should work ok, but notice the band saw (induction motor) lost power and only slowed when torque fell so low it could no longer turn. D/c motors do need the rectifier as shown to produce pulsed d/c. Excellent video, I have 2 treadmill motors and 4 power chair motors to experiment with.

Thanks Mike, worked great! I used a different controller (P/N 090456) and the potentiometer that is already installed on that unit works great. The first 1/3 turn does nothing but after that I get full variable control from very slow to top speed and everything in between. I also mounted the rectifier on a heat sink from an old dell PC, not sure if necessary but using on a lathe and just want to keep everything cool. Excellent video Mike!!

You should be able to get that full range back by adding a resistor to one of the leads going to the pot. Just use your dmm to get resistance ohms just before it starts spinning. Lets say its 200 ohms. Just add a 200 ohm or maybe 180 in series with one of the wires going to the pot and you should have mostly full range back.

Mike, you did a great job on the videos showing how to use the DC motor, you showed me that I remember more of my electronics I learned but never used in the USAF. Aircraft maintenance was a case of drag it out of the rack and shove another one in it's place and send it back to the factory to be repaired. That 22 weeks of basic electronics school was a waste of time! An idea for another video, figure out how to get the stepper motor from the tilt unit on the treadmill to work. I would like to put casters under my wood lathe and use the tilt unit to lift the lathe off the floor. I have a bad back and can use some help.

Hi Mike, finally got all the parts together and it works a treat👍👍👍. The potentiometer that came with the controller seems to work quite well so I probably won’t change it. I couldn’t for the life of me remember where I put the bridge rectifiers I bought so I used the one I found on the circuit board. Next job is to mount it in all control box. I will also use the iron ring on the wires as well as the power filter that came with the treadmill. I don’t know if the filter is necessary or not but as I have it I figure I may as well use it. When ordering the bits and pieces I took the opportunity to also order a tacho so that will also go in the control box as well as an illuminated master on / off switch. Thank heaps for your very informative video. Cheers Stuart 🇦🇺

Thanks for this demo. I would suggest adding one or two fixed resistance resistors (about 10k ohms) in series with the potentiometer. If placed on the correct side of the potentiometer it will allow you to use the full range of the potentiometer instead of 3/4. (Trial and error). The ramp up time may be important. I am fitting a similar motor to a Boxford engineers lathe. It is 2.5 HP and its resistance when stationary is only 2.2 ohms. That means that when you apply 180 volts without the ramp up, it could draw 82 amps and blow out your circuit or a fuse. Once it is spinning it acts like a generator causing a voltage opposing the supply voltage. This means that the effective voltage is decreased to supply voltage minus the reversed generated voltage and once up to speed it limits the current. For this motor it draws 8.5 amps at 4700 RPM. There is a better method now available with units from China HQ-SXPWM-X for about $US57 plus tax and free shipping. This is specifically designed for controlling DC motors of various voltages. Different models for different voltages. This is being discussed on the Boxford users group.

I have a variable speed controller with a 500K potentiometer driving a DC 180v motor. The motor has an RPM of 4000 but I really only want to use a range of 50-400RPM. When using the potentiometer I'm finding it is overly sensitive and isn't giving me the control over the lower RPM that I need. Would adding a fixed resistor across the Pot reduce the range of RPM? If so what value resistor should I start experimenting with and which wires does it need to intersect?
@Evan-e-cent
@Evan-e-cent 3 жыл бұрын
​@@danielrogerson6635 Hi I see you are having fun with this. I think what you need is a fixed resistor in series with the potentiometer. This is how I think about it: You appear to have a two wire connection for the potentiometer rather than three. So the circuit is being regulated by reading the resistance. You check all this with a multimeter. I have the HQ-SXPWM-X controller and it uses a three wire connection. A reference voltage of 5 volts is connected to one end of the resistor inside the potentiometer and the other end of the resistor is connected to ground. This creates voltage gradient along the length of its internal resistor. Then the wiper moves along the internal resistor and picks up the voltage at its current position. If turned to half way it reads 2.5 volts. At 20% of the way along it reads 1 volt etc. So the controller circuit is being regulated by the voltage. Your SCR circuit appears to be different. (I have one of these $15 SCR AC speed controllers and it runs a sewing machine motor really well, straight out of the box.) Yours only has two wires connected to the potentiometer as far as I can see. One wire would be connected to one end of the internal resistor and the other wire must be connected to the moving wiper. If you have an old potentiometer pull it to bits to see how it works! The circuit must be controlled by the resistance it sees. I imagine that it goes fastest with zero resistance. If so, when it is turned fully clockwise to maximum speed the wiper is connecting almost directly to the other wire. That is one wire is connected to the wiper and the other wire connects to the clockwise end of the internal resistor. Lets say the potentiometer has an internal resistor rated at 100,000 ohms and it is a linear scale rather than logarithmic. Now if you discover that you have to turn the knob 75% of the way before the motor begins to turn, the resistance the circuit is seeing is 25% of 100,000 = 25,000 ohms. It is only using the top (clockwise) end of the resistor. Then you need a 25,000 ohm variable resistor to give you full range. The RPM should vary from 0 to 4000 as you rotate the knob of the 25,000 ohm potentiometer. However you only wanted 400 RPM, that is 10% so you only need the first 10% of this 25,000 ohm range. So you would need a 2,500 ohm variable resistor followed by a fixed resistor to make up the total of 25,000. Ideally a fixed resistor of 22,500 ohms. You may be able to get 22 kOhms, but if not any where from 20,000 to 25,000 would probably be good enough. This should give you a speed range from 0 to 400 RPM. If you put a 'shunt' resistor in parallel with the potentiometer you can calculate what happens to the overall resistance R from the formula: 1/R = 1/R1 + 1/R2 Where R1 and R2 are the two resistors wired in parallel. In your case one would have a variable resistance. If you had a shunt resistance that is lower resistance than the variable resistance you could increase the variable resistance towards infinity (1/R=0) and the shunt resistor is what the SRC circuit would see. You would not be able to turn the motor down to 0 RPM. My video about how pulse width modulation and variable frequency drives work is on my lathe channel evan-e-cent. Look for the blue square wave image. I am not an electrical or electronics engineer but have studied science and engineering all my life while working in medicine.

@@danielrogerson6635 I know this is old, however try this. Measure Pot resistance at lower/far left setting as R1. Get your motor at the 50rpm low end you want, then remove power and measure resistance of pot as R2. Now do R2 - R1 = R3. Now get an appropriately sized resistor that is around R3 - 10%, and add that to one of the leads to the Pot. Now when your pot is at Low the motor should not spin, but just a tick above low it will start spinning at close to your 50rpm. Without getting a new pot its going to be harder to get full range between your desired settings. Doing it this way will at least get your control at the low end much closer to where you expect it to be by knob position.

Question: Will this hold the motor to rpm under a small to medium amount of load? I assume that a treadmill controller has some kind of feedback from the motor, so that it increases power if the motor is bogged down a bit, so that it will maintain the speed of the big treadmill belt. Heavy person would then get the same walking pace as a child...?? Or maybe the treadmill controller doesn't do anything but send x amount of voltage for a given setting?
@boots7859
@boots7859 3 жыл бұрын
Obviously this won't as there is now feedback mechanism. The first complicated idea I think would solve this would be to paint the shaft black, draw a small stripe in white paint on it, put a photo-diode across from it so it can get send an interrupt back to a small microcontroller that will increase or decrease the voltage to the motor to increase or decrease torque. Unless there is an easier way to control current, which would also be stymied as the current would increase also as you are pushing the workpiece into the tool..... All in all, a bit more involved and probably can be avoided by just supplying power and maybe running it at a slightly higher speed before starting cutting/grinding.

Not quite enough power for the 20" bandsaw I'm restoring - it came with a pretty dated 5 hp, 3 phase motor. Still looking for that one....

Everyone doing this needs to bear in mind that when you rectify wall power, if you put on a smoothing capacitor then you will be WAY overdriving your motor. The treadmill motors I've pulled are usually rated 90-100 VDC. When you rectify and smooth wall power, you're getting over 160VDC. So bear in mind that your full speed in that case is actually 60% over speed.

@fisharmor

Right. The higher voltage comes from the fact that there are voltage spikes in your line power - it actually can spike that high, and the cap will even it out at the maximum voltage. But if you don't put a cap on it you'll get spikes and also lows, and it'll average out to 120vac. And yeah, if you have a 160vdc motor it won't be a problem, but I haven't seen one in a treadmill. Lastly, you CAN overdrive a permanent magnet DC motor. I drove mine long enough to get a read on how many RPMs it ran at 160vdc and there was no problem, but I wouldn't put it under load or run it for a long time when that high. SOME overdriving is fine, but I don't know how much. I think if you have a 100vdc motor and you're driving it at 120vdc rectified, un-smoothed power, you can probably do that for extended periods.

Thanks for the reply, that was really helpful! I have a few treadmill motors, some 90VDC and at least one 130VDC. I plan on restoring a bandsaw that was rescued from the trash and I think it will work out. Thanks again for the explanation.

I tried this yesterday and got it working. I used a BR5010 bridge rectifier, and 110v 4000w controller, and a 1HP treadmill motor. (My controller is the two inputs- two outputs variety.) Ive had no trouble so far, but it pays to be skeptical about the wattage ratings on these cheap imported parts. Eventually I intend to control a larger motor with the 10,000W type, hoping that the rating is realistic. I have yet to try the proposed solution to the problem of not being able to power on at a set speed, but rather having to zero it out first, but that would be a welcome change for the people that find this annoying. I'd also love to be able to add a board with a electronic tachometer with RPM readout. If anyone can offer information on this, please let us know, much appreciated.

Awesome! Would there be any benefit to running this setup with 220V instead of 110V? I have it available in my garage, I'm running the 1hp AC motor for my belt grinder on it with a VFD before I knew better, and I'm going to use a treadmill motor for the mini-lathe I'm building. Also, it might be worth mentioning, I think that GFI circuits have a really hard time with the soft starts. I have a relatively new home, and all the 110 outlets in my garage are connected to a GFI outlet, which is a pain...

Hi great video and thank you. One quick question and I would appreciate an early reply. Can this motor controller be used to replace the original speed controller board on my treadmill and can I use my treadmill thereafter? Rephrasing that question, will this speed controller be able to handle the load of a man running on the treadmill?

Hi- Love the video. I plan on using this to power a few machines, but have a question... How did you run 220v out of a single wire? I have several 220v outlets in my shop, but they have 2 120v lines and a neutral in them. I was told splicing the 2 120v wires together would cause a literal melt down, so I'm curious how you managed it. Did you use a US to European voltage converter? A transformer? Something else?
