Your videos have been a huge help in setting up a dc motor conversion for my wood lathe. My MC60 controller is completely missing this resistor and I was wondering if you had any idea what the wattage of the resistor might be?
@dazecars

it's probably not more than .25 watts. good news is the wattage size is just max capacity so you can replace it with the same wattage or bigger and it will function as designed. The only down side is higher watt resistors take up more space.

Great job, thanks a lot. Can you make video how to use MC5100 board.

I con't because I have not worked with one. I have looked at pix and it look similar to the 2100 and is likely PWM driven. The trick too "hacking" it would be to get a pin out sheet that would likely be inside the treadmill.

Not seen any of these circuit diagrams to understand exactly what it is.. but my guess is the R42 is part of an "open loop derivative" or ( fast response feedforward) circuit. Every time the knob is rotated ( depending on how fast/ slow you do it) , an additional proportional voltage. is added.. to your speed setting.. This slowly decays to zero after some time. ..Other " motor/load related or dependent" control in open loop that can compensate much better & faster is known as I×R compensation.. this is ( adjustable) always active in high performance motor control systems.

Videos on speed control of DC motors I've seen focus on providing a knob that does something like an accelerator pedal. *I'm looking for cruise control.* I've seen your video on adding a tachometer to monitor RPMs. I want to set RPMs and have that control motor speed. Have you shown how to do that and I missed it? I have (2) "3.5 HP" DC treadmill motors and the associated electronics, one from a Nautilus and one from a Life Fitness. I also have a smaller "1.5 HP" DC motor from a no-name treadmill. I'm pretty sure the latter came with an SCR.

I know how it could be done but I don't know exactly how to do it. With a tach input, a digital potentiometer, and a a raspberry pi controller you could set a speed and in theory it would "cruse" not sure the lag time as far as adjustments to speed changes due to load, and I have no idea how to program the firmware to control the system. but it is totally do able... just above my pay grade

How can I tell what kind of board came in my treadmill I would like to hook up a potentiometer to adjust the speed but can't find where to wire it up

Only a few boards use the potentiometer, some require a PWM signal generator, and others can not be hacked. What is the board model number of what you have?

All the boards I have a hack for I have made videos about: MC 2, MC 60, MC 80, MC 1000, MC 2000, MC 2100, and MC 1650ls. If it’s not one of those, I don’t have a hack for it. Not all treadmill motor control boards are easily hackable.

There's a good morning. Could you send me a wiring diagram for an M60 treadmill board through a potentiometer, through, LED Tachometer and through the on-off switch, the circuit breaker that comes in the treadmill. Oh, I would like just a complete wiring diagram on how to wire up an M60 board from start to finish. Out of a treadmill, to a DC motor high. I am not an electrician. It I don't understand it, but I wish you would send a complete diagram, I've watched so many KZitem videos. I am really getting more confused. I need help. Thank you. ?

The RPM meter should have come with a wiring diagram and is on its own from everything else. As to the MC60 I can take the time to draw something up but you need to contact me through my website.

I have found if you leave the r42 clipped and just use a 5k potentiometer instead of the 100k it works fine. What is your take on that
@dazecars
Жыл бұрын
I played with that exact thing prior to shooting this video and found only a slight effect in varying the potentiometer size. The slight improvements I did see were not even close to the improvement of reconnecting the resistor.

There is not really much material there for me to do a video. this is the info I have on it: "6-8 MPH- Clipping this resistor changes the IR Compensation from a 15 KV motor constant to a 17.6 KV motor constant. This allows the use of motors of different specifications."

@@dazecarsI have 2 dc motors one that came with my MC60 it’s almost identical to the one you use for bench tests, it’s rated for 18amp and 1.5 HP cont. @ 95v dc. The one I ended up using though is 2 HP cont. @ 130v dc but no amp rating. When I have the tach that’s on the board turned all the way up and the actual tach used for speed control turned up the motor ends up cutting out when I exceed 3000rpm. Could this be because of this resistor and the board cutting power to protect itself or maybe the motor exceeding its rpm rating and trying to pull more power than the board will allow? It’s configured with a 1 to 1 gear ratio and I’m using the flywheel still, the motor shaft extends out both sides and I’m able to have the pulley wheels on one side and the fan and flywheel on the other.

Im just guessing here but I think you are drawing more amps than the power supply can put out and it is shutting off because of that. Amps go up as the motor experiences a load SO disconnect the motor from what it is driving and see if you can take it above 3000 RPM. If it goes faster than 3000 than amps was the issue. This can be resolved by getting a higher amp power supply or gearing the motor. @@FTADaddio

@@dazecars that was my first thought as well, however it was under no load when testing it. Do you happen to know how many amps an MC60 is able to output? Also I’m still using the power supply board from the treadmill as well to power the tach.

It could be just the resistance from the flywheel especially at the 1:1 ratio. have you calculated the torque specs for either motor?@@FTADaddio
